Opalized Turkish Colla Wood gem 9/8/2017 01 - 48 x 26 x 6.2
mm - 51 carats - This beautiful opalized wood comes from
Turkey and has copper secondary inclusions of chrysocolla,
azurite, malachite and more. They called this material "colla"
from the sky blue chrysocolla present in the early digs.
Today, very little of this wood has the gorgeous light blues
present in this rare and world class piece. This gem was an
absolute pleasure to cut and I couldn't be more happy with
the finished stone. This cab also has shiny metallic
hematite inclusions in the brown areas that look like wood.
Cut to a designer drop shape, this cabochon has a
beautifully rounded dome, generously girdled sides and a
flat beveled back all with liquid high gloss luster. A world
class, unique and very rare gem. Here is a video clip to see
the stone in motion: https://youtu.be/EFN8P9tHV7E $300.00
