Stone of the Month
Green Paraiba from Mozambique
This month we feature a stunning paraiba from Mozambique. When people hear paraiba they generally think of that classic Caribbean blue. However, just outside the more well-known blue spectrum lies a varying palette of greens—still holding that fluorescent glow for which we have come to know paraiba, but with varying levels of green, yellow, and hints of blue.
Green paraibas were uncovered in the original Brazilian find, through to the Nigerian discovery and right down to the most recent find in Mozambique. This 5.37-carat Mozambique paraiba has a strong grassy green hue with traces of yellow and blue, a beautiful mix that shifts color in different lights. Precision cut and nearly flawless, this is a top-notch collectable gem.
This is a massive 15.2-carat oval brilliant with a pleasing violet-ish blue hue. It's certified by the DSEF lab out of Idar-Oberstein in Germany as a natural, no-heat blue sapphire.
This 7.9-carat umbalite garnet has a striking color, unlike many we have seen come from the Umba valley in Tanzania. The melange of pyrope, almandine, and minor spessartite produces a striking mix of maroon, purple, and magenta in this unique gem.
This a duo has similar upbringings but very different features. Born of zinc and sulfur, these two minerals could make great ore for extracting zinc, but in this case they crystallized into fine specimens.
