Lot of 19 premium loose moissanite gems totaling 44+ carats. Mostly round brilliant cut with a few fancy shapes, in a range of colors: white, off-white, blue, green, gray, and amber. All gems are excellent cut and clarity, authentic (see photo), and were purchased for personal jewelry projects that never came to fruition. Priced well below what you’d pay sourcing these individually. At current market rates for high-quality moissanite per carat, this lot is a strong value that’s ideal for a jeweler, custom designer, or reseller looking to move them individually.

Old JTV purchase. This is a sweet little stone... very brilliant with a lovely medium periwinkle shade. The dominant hue is blue with a violet modifier. It's a super stone for this price range. Completely eye clean. Weight is 1.35ct and dimensions are 8mm. Mined in Tanzania.

Old JTV purchase. This guy weighs 3.30ct and measures 9mm. The cut is called an "emanating star." It's much more brilliant in person. The color is a vibrant apple green with excellent clarity (eye clean). Mined in China.

I bought this from JTV way back in the day. It was sold as a "pure" pyrope, which is supposedly quite rare, as most are mixed with other garnet varieties (like almandite and spessartite). It is 5.02ct and measures around 11x9mm. It's a scissor cut, which I love. The color is a deep, full-bodied blood red with the facets positively lighting up in large, electric flashes of scarlet. It's very brilliant and very fiery. Completely eye clean or better. This is not to be confused with those overly dark, dull, dead, brown-red garnets. This is probably the finest pyrope material you can buy, and it's just impossible to find in this quality and size. From Mozambique.

Swat Valley emeralds stand out as collector and cutter favorites because their vivid, natural green hue and clean translucency rival top Colombian stones without needing heavy treatments, offering unbeatable purity and investment potential as prices rise 10-20% yearly. They're brutally hard to get—formed in razor-thin high-pressure veins requiring a rare beryllium-chromium mix, mined at 8,000+ feet in avalanche-prone, unstable Pakistan borderlands accessible only by mule or foot, with most rough shattering from inclusions, leaving intact pieces like gem lottery wins. Demand stays sky-high among serious buyers chasing these scarce, undervalued treasures before artisanal veins run dry and auction values soar.

80+ carat natural ruby with a striking purplish-red body color and a unique holographic visual effect. This exceptional gemstone displays visible hexagonal crystal structure patterns, creating a rare internal geometry that shimmers under light and gives the stone an almost otherworldly depth. Cut as a smooth, polished cabochon, it highlights both the natural inclusions and crystalline growth features that make this piece truly one of a kind. Heavily included with mineral inclusions that add character and authenticity, this ruby is ideal for collectors, lapidary artists, or statement jewelry. The large size, uncommon optical effect, and visible crystal habit make it a standout specimen for those seeking rare natural rubies with distinctive visual phenomena.
