My love, she comes in colors.
— Arthur Lee, Love
business of judging precious stones is an eclectic one, not for
the timid or shameless. The appraisal of precious stones involves
decisions both conscious and unconscious. Try as we may to slice,
dice and pigeon-hole the elements of quality, in the end an analysis
of their features requires more than just a formula, just as
fine cooking involves not simply ingredients and a recipe. It
is about reaching for factors beyond the immediate senses, and
in that respect is quite like enjoyment of fine art, food and
While one man’s Miles Davis might be another’s Kenny G, there are certain things that the discerning among us look for. Thus, what I will try to convey to you in the following passages is educated emotion, something to help separate the long, languid lines of artistic truth from aimless noodling. Here you will find the ingredients, the recipe, the score. But without the passion that only the viewer himself can bring, both these gems and our time on this precious planet are a waste.
With that introduction, let us now examine blue sapphires. Here I have a confession to make. Blue is my favorite color. I love blue. Thus the following essay is one of love.

Kashmir Blue Velvet
This fair dame is placed upon a higher pedestal than all others, only to have it ripped out by every Tom, Dick and Malagasy. First, let me let you in on a base little secret. The Kashmir mine has produced jack-doodle since the 1930’s. And the lion’s share of production came out during a half-breath period of just seven short years from 18811887.
But these were the halcyon days! If one factors in the brief three-month summer mining periods, within less than thirty months, this tiny land slip high in the Indian Himalaya attained a reputation that has left the world mumbling ever since about having seen the light.
What is it about the Kashmir stone that I find most attractive? I suppose it is staying power. Plenty of sapphires look magnificent under one light, but when brought into another, shed their beauty faster than a K-Mart daisy. Not so for these gems from the mighty Himalaya. The finest Kashmir stones shine the blue fantastic in all lights, be it candles in that romantic little downtown French bistro, or beneath the garish fluorescents in a suburban supermarket’s meat department.
What else do I like? I like their texture, that softness that envelopes all like a sticky blue blanket, banishing darkness with that bluest of blues. To get hypertechnical, we can call it a removal of extinction, a scattering of light off the extremely fine silk, which is just enough to exile the night, but not enough to materially affect transparency. Note that here we have a direct contradiction of the laws of diamond grading here we have inclusions contributing in a major way to the beauty of a gem.
And what don’t I like? Do you take me for a fool? A good lover accepts the defects as the price of admission. They are nothing but the flaws in a fine leather, a blown note betwixt the sweet sheets of a Coltrane sonic masterpiece.
Mogok Round about midnight
Blue midnight. The blue of the finest Mogok stone is something beyond vivid, beyond intense, into a realm where blue, black and lust intermingle. But black is perhaps too strong a word, for there is nothing black about a Mogok blue. To visualize this, think of the color of a desert sky about 15 minutes after the sun has set, with stars rising in the distance. This is the color an intense azure hue matched in the world of gems only by the finest tanzanites (ten carats plus here).
Does all of the Mogok stone display this color? Of course not. There are Mogok blues that entirely resemble the lightest of Ceylon sapphires. So understand that we are talking about ideals here.
What don’t I like? Cracks, fractures, fissures, faults, label them as you may, Many Mogok stones are cursed by these destabilizing distractions. Pox on cracks, and the horse they rode in on.
What else? Some Mogok blues are so very intense that they suffocate. But even these are still interesting in the proper light. Oh, Mogok, how I love you let me count the ways sorry, I can’t, there are just too many.

Dame Ceylon, what you have been through, how your fair name has been besmirched. So many look down upon you. But fear not. The nay-sayers are nothing but novices, those still waiting to have their minds blown by your unique take on the blues. For when you are in your prime, you are the equal of any. Let me say it again the finest stones from Serendib can blow with any blues on the bandstand.
Top-shelf Ceylon (today, Sri Lanka) sapphires have something I will hereafter refer to as snap. Like the pointed slap of a stick against a taut snare’s skin, the color of certain Ceylon blues has an ocular attack unlike any other in the sapphire world. It slashes the eye like a razor, similar to a cobaltian blue of the finest Lanka spinels. Such stones have that which makes electric blue electric, and in the Island of Gems are often compared to the blue portion of a peacock’s feather. Incidentally, this is also true for gems from Kashmir, which bear a far greater resemblance to those from Ceylon than to Mogok blues.
Both Sri Lankan and Kashmir stones suffer from a tendency towards depth down below. Due to the shape of the rough, fashioning the biggest stones is often an exercise in butt padding. Zoning is also a problem. When you are examining these gems, don’t forget to rotate them through a full 360 degrees. This is, of course, apropos in the evaluation of any gem, but of utmost importance where zoning is a problem. Pay particular attention to areas where the color might wash out.

The perfect sapphire
A fine gem has an unmistakable sexual quality to it. This should come as no surprise. Both subjects involve a good measure of passion. But the finest gems are like the finest people. Their beauty grows with time.
Some sapphires drive you crazy the moment their azure legs slither from a stone paper, leaping onto the cocktail table and saying: Baby, let me walk on your back with my high-healed pumps! These have a fast rise time. But there is a difference between love and lust, the subtle versus animal desire. Each has its moments. But in lovers, as with gems, I look for staying power, those which combine the cerebral with the physical. For the physical alone is not enough.
The beauty of love is its sublime, understated nature. It offers you a glass of wine and conversation, before suggesting at the end of the evening that the two of you retire to the boudoir (just for friendship, of course). In my experience, such attraction is an emotion that develops with time. Exceptional gems grow on you. They are experts at hiding, more interesting with every listen, more exciting with each glimpse. When you gaze at their beauty for hours, days, weeks, years on end without tiring you know you have a fine gem. That, my friends, is what I call love. This takes distance, the kind that only time provides.
So the next time you are taken aback by a gem, stop yourself. You may be looking at infatuation. Stand back and judge. Take your time. What you want is balance Buddha’s middle path pure animal sexuality and love a fashion model/pornstar lover who left the business to pursue a dual doctorate in physics and fine arts.
And just what, pray tell, would the perfect sapphire look like? My dear friends, that would be akin to finding the perfect woman or man. Leave D-Flawless to the gem of the common man it doesn’t exist in sapphire. Don’t seek perfection, just look for something you can spend the rest of your life with.
First, let me say that there is a definite market ranking for sapphire according to origin. It unfolds as follows:
That said, I would like to be allowed to burst
all your bubbles. Origin is not what’s important quality
Permit me to relate the following story. A number of years ago, a pit was discovered near Elahera on the Island of Gems Sri Lanka. The stones from this mine bore such a resemblance to those of Kashmir that many labs actually issued papers certifying Kashmir as the source.
In light of the above, if the major domo of a lab is not able to promise you his/her first-born child in trade when, at some later date, he or she is proved wrong, then do not accept the paper offered. For what good is it?
Back in the good old days, origin was based not on where a stone came out of the ground, for there was no sure way of proving the geography of a stone, but on the appearance of a stone relative to the typical appearance of stones from certain classic sources. Thus a Ceylon sapphire that looked like a Kashmir stone, became, de facto, a Kashmir sapphire in the market. Similarly, the Mogok stone that resembled a Ceylon, became a Ceylon.

origin is today determined largely by invisible scientific criteria,
as opposed to obvious physical attributes. Rather than biting the
bullet and devising the means of judging aesthetic beauty (or admitting
that it is beyond reach), laboratories are today handing us the
ultimate silliness, a forehead-angle measurement of intelligence.
If asked to judge a Miss Universe pageant, such gemologists would
probably make the determination based on a DNA signature.
But what can I say? We are often confronted with ridiculous laws. In West Virginia, it is legal to beat your wife so long as it is done in public on Sunday on the courthouse steps, while in Denver, it is against the law to lend your neighbor a vacuum cleaner. And lest we neglect our neighbors to the north, in Canada it is against the law to board a plane while it’s in flight. Yes, these are the laws of the land but there are clearly cases that call for a little civil disobedience. Thus one may make use of origin reports, but use them only as a guide, not for a final determination of the merits of a fine gem. Dare to disagree when common sense dictates it. Don’t blindly trust the machine. Personally examine the ballots when necessary.
A short time ago I had the opportunity to view a particularly fine sapphire. Its actual origin, I will not say for that prejudice would simply detract from its magnificent beauty, manifest to all which view gems with heart, rather than microscope, in hand.
Ilke Bahn, our goldsmith at Pala International, had just finished placing this jewel in a handmade mounting. And this mounting only served to enhance the beauty of an already stunning gem. Like the Vietnamese ao di, a diaphanous garment one observer described as covering everything but hiding nothing, this sapphire’s beauty shone to greatest distraction. Ilke handed the azure beauty to me to with a gleam in her eye the secret of the night sky palmed to an innocent. It was impossible to take my eyes off it.
will never forget a night several years ago when a close friend
and I were camped out in the desert at Joshua Tree. Sometime after
midnight, as we wandered the boulder-strewn stillness, our gaze
was drawn to the heavens. Stars carpeted the night from horizon
to shining horizon, the Milky Way cutting a swath through all of
everything and nothing. As the night wore on and the sky
rotated, my consciousness shifted as well. I realized for the first
time my place on this spinning ball. The words of my friend still
echo obvious, yes but a truth that had eluded me
for so much of my life: This is out here every night, he
said. All we need is to raise our eyes up above the horizon.
Up above. So simple, so elegant. And down below. I had a similar experience while I gazed down upon the ring Ilke had created. As I squinted and peered, a silken world spun by powers beyond my imagination twinkled within a secret whispered just for me. Here was such a special stone, beautiful at all angles, from above and below, at all and any magnification.

Call it a signal from the Gods, a voice from the heavens, an eruption from hell epiphany describe it as you like. I put it thus: at that instant in time, the sun broke through the clouds, the planets aligned. As I held that sapphire ring in my hand, I witnessed the birth of earth and all creation. I gazed upon Pangaea, saw the continents form, then separate. Like that starlit sky in Joshua Tree, the true majesty of mother nature struck me. This sapphire was from Madagascar.
If my readers take away anything from these few lines of prose, I hope that it is that we should each make use of our own eyes in judging gems. Read the law, listen to the pros, but always rely on your own eyes. Let this be the lesson buy what looks good to you dip your own spoon into the broth and taste for yourself. Yes, let experts guide you, yes, buy quality, but in the end, your own senses are the final arbitrator, not those of the seller or of the labs. After all, it is you who will reap the benefits of ownership of this wonderful sample of nature’s beauty, not they. One of my first teachers explained it thus: An exceptional gem is like an exceptional woman they come in all colors. Yes, indeed, my love, she comes in colors.

Blue Sapphire Buying Guide
Introduction. The term sapphire alone describes the blue variety of gem corundum. Other colors have a color prefix, i.e., yellow sapphire, green sapphire, etc. The term ruby is reserved for corundums of a red color. In Asia, pink corundums are also considered rubies. Outside of Asia, such gems are generally termed pink sapphires.
Color. For sapphire, the intensity of the blue color is the primary factor in determining value. The ideal stone displays an intense, rich blue without being dark or inky. Stones which are too dark and inky, or too light in color, are less highly valued.
Lighting. Sapphires generally look best viewed with fluorescent light or daylight (particularly around just after sunrise and before sunset). Incandescent lights, whose output is tilted towards the red end of the spectrum, do not do most blue sapphires justice.

Cut. In the market, sapphires are found in a variety of shapes and cutting styles. Ovals and cushions are the most common, but rounds are also seen, as are other shapes, such as the heart or emerald cut. Slight premiums are paid for round stones. Cabochon-cut sapphires are also common. This cut is used for star stones, or those not clean enough to facet. The best cabochons are reasonably transparent, with nice smooth domes of good symmetry.
Prices. Sapphire is one of the world’s most expensive gems, with prices similar to those fetched by fine ruby or emerald. But like all gem materials, low-quality (i.e., non-gem quality) pieces may be available for a few dollars per carat. Such stones are generally not clean enough to facet. The highest price ever paid for a blue sapphire was the 22.66-ct. unnamed Kashmir sapphire once owned by James J. Hill (the “Empire Builder”), which sold in 2007 for $135,216/ct. This sale barely topped the previous record: the 62.02-ct. Rockefeller sapphire, which sold in 2001 for $48,871/ct.
Stone Sizes. Blue sapphires occur in far larger sizes than ruby, with Sri Lanka being the home of most of the faceted sapphires of quality in the 100-ct. plus range. Any untreated ruby of quality above two carats is a rare stone. Fine untreated rubies above five carats can be considered world-class pieces.
Phenomena. Sapphire may display asterism, the star effect. Fine star sapphires display sharp six-rayed stars well-centered in the middle of the cabochon. All legs of the star should be intact and smooth. Just having a good star does not make a stone valuable. The best pieces have sharp stars against an intense blue body color. Lesser stones may have sharp stars, but the body color is too light or grayish. On occasion, 12-rayed star sapphires are found.
Name. The name sapphire is believed to be derived from the Greek sappheiros, a word for blue. It is likely that the word sapphire was first applied to laps lazuli from Afghanistan. According to Oriental beliefs, sapphire is the gem of Saturn. It is also the birthstone for September.
Sources. The original locality for sapphire was most likely Sri Lanka (Ceylon). Fine stones have also been found in Kashmir (India), Mogok (Burma), Madagascar, Thailand and Cambodia. Dark, inky blue sapphires come from Australia, China, Vietnam, Laos, Nigeria and a host of other localities. Fine blues of small size have been mined at Yogo Gulch, Montana (USA), while lesser stones have been produced elsewhere in Montana. Other sapphire localities include Kenya, Tanzania, Malawi and Rwanda.
Enhancements. Today, the vast majority of blue sapphires are heat-treated to improve their appearance. The resulting stones are completely stable in color. In lower qualities, heat treated stones sell for roughly the same as untreated stones of the same quality. However, for finer qualities, untreated stones fetch a premium that is sometimes 50% or more when compared with treated stones of similar quality. Other treatments, such as oiling, dying and surface diffusion are seen on occasion. As with all precious stones, it is a good practice to have any major purchases tested by a reputable gem lab, such as the GIA or AGTA, to determine if a gem is enhanced.
Imitations. Synthetic blue sapphires have been produced by the Verneuil process since about 1908 and cost just pennies per carat. Blue sapphire has also been produced by the flux, hydrothermal, floating zone and Czochralski processes, but such stones are rarely encountered. Doublets consisting of natural sapphire crowns and synthetic sapphire pavilions are fairly common, particularly in mining areas. Synthetics are also common at the mines, in both rough and cut forms.
Lore. According to Indian astrological beliefs, sapphire is associated with the planet Saturn. Although the blue sapphire traditionally comes from Sri Lanka and Burma, it is rarely used in traditional Indian jewelry and Indian jewelers are sometimes reluctant to handle the stone associated with this powerful planet. Although no superstitions of this kind are associated with Islam, the gem was not commonly used even in the Mughal courts. No such fear exists in the West, an sapphire is one of the most popular of all gems. In the modern Western system, sapphire is the birthstone of September.
