GEMSTONE DISCLAIMER   **Please assume all gemstones referenced in both the titles and descriptions are lab-created or synthetic unless specifically listed as natural. If you place any bids we assume you have verified the stones yourself or have been presented enough information and are comfortable with the bid you place. We will not refund any lots for being lab-created if it is not listed "Natural" in the title. We test all gemstones with a Presidium Gem Tester II. Unfortunately, gem testers will not differentiate natural gemstones from their synthetic counterparts. Many gemstones' properties overlap and could potentially be one of many variety of gemstones. We do our best, based on the tester readings, to determine whether or not the item is a specific gemstone; however we are not GIA certified gemologists.
