Comment: Possibly the multi-colored tourmaline with the broadest range of hues I can remember, also hard to find in other gem-types (though titanite does that trick pretty well, too, different in character, tourmaline being calmer, titanite wilder and chaotic). This massive 10mm round piece is a true celebration of colors, a tour around the color wheel, green, red, yellow, brown, orange and all mixes there-of. A kind of gem that is such fun to photograph I need to delete half of the images again. Obviously coming from the dark realm but never without a spark, even in low light. This, BTW, is called pleochroism, not color-change or color-zoning as in watermelon pieces but tourmaline's uniquely quick change of many color-axis, red from here, turn a bit, green then, yellow next, orange to the left, golden to the right, turned some more and.... multi-color turned up to the maximum. See the close-ups with fairies, yellow butterflies, flames in splintered mirrors. We had a dark five carat alexandrite which looked similar in mixed light, green and red in flashes out of the dense earthy body (no luck finding the old images yet). 3*NOS, AIG report, near six carats, plus all WildFish-Extras included. Sparkly in sharp office light, soft rays in warmer rooms, always different though, even a 100% pine green from a direct table-view is possible (see the AIG photo, although they graded it with main-color as 'red'). The beautifully shaped pavillion, with facets mirroring or colors zapping through and through, invites a setting with an open side for extra show effect. Strictly spoken not a precision-cut but deserves to be called out for its beauty. A high-domed ring on slender columns with needle prongs for special occasions or a more solid but also thin bezel for daily use will do just fine. Let us design a bespoke piece of heirloom.
