it seemed the rusian material is very sought after, but it also
seems that most of the fake or lab grown stuff is coming out of
russia. is that correct?
Price of alexandrite almost entirely depends on color change. The
closer you come to emerald by day and ruby by night, the more you
will have to pay. We talking about $10,000 and more per carat. Much
higher prices per carat have been paid as well. Color is everything.
Any shades of brown or grey and price plummets down.
Alexandrite of that quality used to come from Russia. I believe that
deposit had been worked out, however, from time to time, a stone or
two makes it to the market.
From practical point of view, it may take a few years to locate
stone in top quality. The choice is either lab-grown, or accept
My personal view is that all the beauty of alexandrite is in color
change. I would rather have lab-grown, than yellow and brown stones
from other locations.
Do not be surprised that even lab-grown material is not cheap. Most
of lab-grown alexandrite is actually lab-grown corundum with color
change. High quality lab-grown alexandrite can be in price range of
natural diffusion treated sapphire.
