A look at our selection will reveal that we are not gem dealers. The items we include for sale here come from our own private collection, with some lots used for setting our own jewelry. What we mean to say is, these are all high quality pieces that have passed through a selective eye, rather than readily available gems for sale. None of these are for sale like available "stock" in a store. Which explains why the prices may look too good to be true - we use these gems ourselves! We are artists/craftsmen/jewellers with plans to use the gems you see here some day. But until then (and for cash flow reasons), these are available to similar minds. We have a store in Singapore called the Singapore Island Jewellery Store. We work with commissioned fine jewellery pieces, gemstones, and antique jewellery. We specialize in unheated and high carat gemstones. We do not accept returns at our store. There is just too much processing involved for a small business like ours. We would rather have no sale than to have an uncertain sale. However, because Gem Rock implements a 14-day return policy for all sellers, we will accept returns and charge a 10% restocking fee. Shipping and insurance charges are not refundable. Exchanges may be considered on a case-by-case basis.
