Re: Re: natural ruby value

I'm new to lapidary but I have had an interest in gems and the gem trade since I was a kid. Your Franklin find could be worth, as David said, a few dollars to thousands. The problem with colored gemstones is that color and clarity differences, even subtle ones, can make geometric differences in value. For example, the ruby found in some African (green) zoisite, the parent mineral of Tanzanite, is usually beautifully colored but so opaque that it is of very low value and used most often in the parent rock for larger ornamental carvings/turnings, etc. On the other end of the scale, fine Burmese pidgeon-blood red ruby can go for phenomenal sums. Some years ago, an 8 carat oval cut stone with obvious large inclusions but of exceptionally rare color went at auction for $1oo,ooo- per CARAT. One of the best ways to get a feel and appreciation for the value of a stone is to browse in high end jewelry stores where you can see for yourself what top grade stones should look like. The slaespeople are often certified gemologists, and are happy to contribute to your education. You might also seek out a master cutter's opinion. High-end jewelers can help you there, too, and perhaps the mine operators can recommend a reputable cutter. Good luck!
