Some new amethyst gemstones to add to my gemstone stock, left to right: 10mm round 3.6ct (approx), 8mm round 1.8ct (approx), 9x7 oval 1.8ct (approx), and 6mm trillion .70ct (approx). Gem weights are given in approx measurements, as I have multiples of these, and even though the diameter size may be the same per each cut, they can still vary slightly in weight. Let me know if you would like a quote on something made with any of these.
