Other Rough

Oregon Sunstone from the high deserts of Oregon State. This was found over a 3+ day period. Total weight is 459grams; average weight is about 5-6carats; color is clear, pale yellow or some hint of color - schiller can be seen a decent number of pieces. Would recommend that this material be faceted abroad to increase the return of investment and profit. The sizes should vary, but on average, would think this should return an average of a carat or more when faceted. Sell a few pieces of this material and recoup the cost of the rough! This material is too small for us and unfortunately, we did not find anything of high color and the trip to dig was an overall loss, but the experience was worth it!

459grams - $215 including postage (Contact us for International shipping quote)

Below is a photo of 100grams of the parcel for sale.

African Garnet, mostly bright red with a few orange reds. Average weight is about 1.2 grams. Bought a number of years ago. Sold a sample to a cutter/wholesale gemstone dealer who has faceted it and sells it as Chrome; he has been getting $90/ct wholesale for it. In seeking to determine if this is Chrome or not, I have asked a local GIA Grad who does appraisals and has a gem lab which includes a spectrometer, as to whether a Chelsea Filter could be used to determine Cr content in a "red" gem. Have also checked with the GIA library and they sent some articles and information on using the Chelsea Filter with a red gemstone. It seems that red gemstones under a Chelsea Filter will be a dark or brown red if there is no Cr. If there is Cr, the color will be a bright red when viewed through the filter. This rough, when lit from the side or from behind using fiber optics and then viewed with the Chelsea, shows a bright ruby red. Whether it is true Cr containing garnet or not, the red is very nice, glows and a dealer has been selling it for $90/ct - so, like many other gemstones out there, the color and not necessarily the elemental content or location should be the reason why one makes a purchase.
