You don't say whether you're certain it's natural. The largest known cut natural bixbite I've heard of to date is around 8 carats although larger ones may exist. A 12 carat natural stone, if nice, would be very valuable and probably a candidate for a museum collection. Have you had it evaluated by a gemologist?

Synthetic hydrothermal bixbite, on the other hand, sells for around $7 a carat in the rough. Figuring 60% cutting loss (depending on the shapes of the rough and the finished stone it could be more or less) a 30 carat rough would be needed to finish a 12 carat gem.

dear Richard,

Thank you for your reply.It has just been given to a gems institute to get its appraisal.Let me tell you that the treasury has been found in Africa in an area where there were no such (enhancing)technichs for synthetic gems 50 years ago.So if it comes that it is a natural cut gemstones of 12, what should I do?Wold you assit me?There is another stone of 8 carat not yet identified but similar to the red one.it is yellow/orange.
cheers

How interesting! A 50-year-old natural bixbite of 12 carats from Africa would be a newsworthy event. Was it found in Nigeria by any chance? By all means share the gemological report with us here and give us all important details, including the name and location of the firm. Be sure to tell us what the report says that distinguishes the stone as natural red beryl.

A yellow-orange stone could be anything: corundum, spinel, tourmaline, garnet, topaz, quartz, zircon -- and many others.

Is it pink, and rather opaque? Or, is it translucent?

Or, is it red and transparent?

Or, is it scarlet and transparent?

Have you had a positive ID made on the red cabochon cut stone yet?

I'd be surprised if it was a red beryl. Quartz (carnelian) would be my guess.
