**Montana Sapphire – 2.9 Carat Pale Blue Unheated Cabochon** This natural **Montana sapphire** weighs 2.9 carats and features a soft, pale blue color that highlights the stone’s organic beauty and subtle elegance. Cut as a smooth cabochon with a high-polish finish, this gemstone displays a gentle glow and natural translucency that enhances its character. Sourced directly from the mine in Montana, USA, this sapphire is **unheated and untreated**, preserving its completely natural state. The presence of natural inclusions further confirms its authenticity and makes each stone truly one-of-a-kind, ideal for collectors and custom jewelry. By sourcing the rough material directly from the mine and cutting each stone in-house, this allows for **wholesale pricing without sacrificing quality**, offering exceptional value on a genuine, natural Montana sapphire. Montana sapphires are highly sought after for their ethical sourcing, American origin, and unique range of colors. Their softer, earthy tones are especially prized among collectors and designers seeking something distinct from traditional commercial sapphires. Sapphire is one of the most valuable gemstones in the world, second only to diamond in hardness (9 on the Mohs scale). Its combination of durability, rarity, and natural beauty makes high-quality sapphire increasingly desirable. Fine sapphires form over millions of years under specific geological conditions, making well-colored, untreated stones particularly rare and valuable. This 2.9 carat cabochon is perfect for collectors, jewelers, or anyone seeking a natural, untreated gemstone with authenticity, character, and direct-from-source value. ---

Rare Untreated Montana Rose Cut Sapphire - 4+ Carats, Color-Shifting Glow Experience the magic of this hand-cut, untreated Montana blue and yellow sapphire, fashioned into a stunning rose cut straight from the mine. Over 4 carats with a captivating moonstone-like glow that dances with light. Unique Optical Effects Tilt by axis: Shifts from cool blue to warm yellow. Interference rainbows add ethereal fire. Rose cut facets amplify vintage sparkle and depth. Why Sapphires Are So Rare and Valuable Sapphires demand rarity from their corundum origins—only specific global deposits (like Montana's alluvial gravels) yield untreated gems with pure, vibrant color. Natural color-change and interference effects like this are exceptionally scarce, formed over millions of years under precise geological pressures. No heat or treatments means unmatched authenticity; top untreated Montana sapphires rival fine rubies in collector value. I sourced the rough myself and meticulously cut this rose cut sapphire, preserving its wild character. Perfect for collectors, jewelers, or statement jewelry. Minor natural inclusions enhance authenticity

Video: https://imgur.com/a/VbpB3wd This is an antique rose cut diamond ring from France. It feautures a large 7.5mm x 6.4mm rose cut diamond that is set in a double bezel-prong setting. Genuine antique rose cuts of this size are very hard to find. Originally the stone was set in a closed back silver setting, however, there was some dirt, so the setting was re-done using a platinum backing, which will never tarnish. The shank is 18k rose gold. There is a faded hallmark on the back of the band, but it is likely the French eagle hallmark. The weight is 2.2 grams and the size is 5; it can be easily resized however. For payment, I use Square invoices. Venmo & Zelle is fine as well.
