Nice Amethyst with good color and cut. Natural and untreated gemstone. Most gemstones bought and sold online aren't jewelry grade -- either poorly cut, have too many inclusions or are low grade color. Of the gems considered to be jewelry grade, many still have one or more issues which disqualify them from being the centerpiece of a fine ring or pendant. This gemstone is top jewelry grade, meaning that it meets all the qualifications to be used as the center stone for high end jewelry. If you take a look at our auction history, you'll see that we sell thousands of carats of gemstones per month. So when we set aside a gemstone as being top jewelry grade, that means that that gemstone has been chosen from hundreds of others as the very best 5% of the stones we bring in.
