 During the regular examination of the goods at the auctions of
Christie's and Sotheby's in 1995 and 1996 by one of the authors (AP) a few lots were
identified as Madagascar sapphires. The prices (best qualities without visible colour
zoning, not heat treated, different shapes of pleasing face-up appearance and not too
heavily cut) listed below are approximations based on auction results and a review (in
Bangkok):
Sapphire between
> 15-20 cts. above US $ 5000.--/ct.
10-15 cts. US $ 4500.--/ct.
below 10 cts. US $ 3000.--/ct.
around 1 ct. around US $120.-- to 200.--/ct.
These figures demonstrate that Malagasy sapphires have rightfully
established themselves on the world market.
