A word about gemological labs. Many if not most people know only GIA and think they are the best in the world. Actually they are barely forth. Even in US when it comes to color stones AGL (American Gemological Laboratories) has a higher status and high-end auctions require AGL reports. Both are no match to Swiss labs; Gubelin being the best (and its report costs $2,000). But when it comes to corundum (rubies and sapphires) GIA is not as good as not only Swiss and as good Thai labs such as AIGS and BGL. After all it was AIGS that identified Mong Hsue Rubies, GIA fails. But BGL is not only special, it is unique. Their requirements are extremely strict. Two gemologists – one from AIGS, another from GIA – have to independently certify each stone and their conclusion must be identical.

But about the stone. As for clarity, it has… I cannot even call it inclusion… some dot of lighter color on the border of table and crown. Stone is very transparent but it is also dark (even though not THAT dark) so you need a good light to see it. Other than that - bright, rich, extremely brilliant big unheated stone.

This stone is close to the top of Upper Good grade and according to Gem World International (Bible of every jeweler, gem dealer and serious buyer and the only realistic price list in the world. Their values, expertise and materials were used in countless legal cases around the world) price for this stone would be around $1,250 per ct ($3,500 for heated according to International Gem Society, $9,000-$12,000 per ct according to born in narcotic hallucinations values of various industry price lists). At gem shows I sell similar stones for $900-$950/ct. As virtually all Fixed Price listings on eBay and Gemrock this one is promotional and the price per ct is ridiculously low - $650 per ct.
