The first Saguaro emerges from predawn darkness, looming above me like a giant being from another planet. The sun rises over Gates Pass. Last night we sat on the porch of our adobe, deep in the Sonoran Desert, with Orion twinkling overhead, listening to a coyote chorus. Today the show opens at the old Pueblo Inn, the traditional first day of jumpstart at the 2009 Tucson Gem Show. (image left; through the front window)
Gem Ruby From Winza
For a Saturday opening, traffic was disappointing, it was brisk enough, but the fact that we found parking without a half mile walk told me that attendance was down significantly from last few years. Sales were few and far between. In one room a dealer motioned me outside into the parking lot and handed me a gem paper. Inside a beautiful 4+ carat ruby from the new strike at Winza, Tanzania. I thanked the dealer. “This is the first one I have seen” I told him. “This is the only one I have seen” he said with a significant look. It is a beautifully cut cushion, with an extremely clean interior and no sign of the long needle like inclusions that that are reputed to be characteristic of the best Winza gems. The stone shows excellent crystal and the color is a unique red hue, lacking both the classic purple secondary of the Burmese or the orangey hue of the best of the old Thai stones and reminiscent of neither. Is it better than Burma? Winza ruby is iron rich, which means that it lacks the UV fluorescence and thus the supercharged saturation of the finest gems from Burma, but the color holds up well, almost no change as I move back into the yellow light of the room’s interior. Winza is located in central Tanzania. Travel addicted gemologist Vincent Pardeau has posted a video showing the Winza gem fields:
Fine Aquamarine from Mozambique:
Moving on to another dealer I am shown a tray of 1-3 carat fine aquamarine, 65% tone with a bit of gray, reputed to be from Mozambique, at another booth I find two fine 5+ carat aquamarine, the first I have seen from India. The darker hue always comes with a certain amount of gray mask. Visually the best of the two shows about 10%. Aquamarine is extraordinarily rare, much rarer than its cousin emerald. In front of me is more fine aqua than I have seen in one place in several years. Stay tuned!
