If it is generic rose quartz, it will sell for $2.00-2.50 per pound. Exceptionally dark color will get you about $3.00-4.00 per pound, and if clear (or transparent) the price will go up quickly. Check past auctions on OKorder for general prices for comparison. Unfortunately, if you sell on OKorder, you are going to get killed on shipping. Try and see if it wil fit in one of the new USPS flat rate boxes.
