Home » Loose Stones » Colored Gemstone
For your consideration is a stunning natural solid white opal from my mother’s private collection, purchased in 1982 in Honolulu, Hawaii. This stone has been verified by Graduate Gemologist Paul Cassarino (The Gem Lab, Rochester, NY). Included is a photo of the original ring. The Opal "swelled" and fell out of it's original custom framing in 2008. This is a high-quality collector's stone with a very desirable color profile. While the body tone is a clean N8 white, the play-of-color is dominated by rare Red and Orange pinfire and broad flashes that are visible from multiple angles, including the profile. Weight: 3.14 carats Dimensions: 14.2mm x 11.1mm x 5.2mm Shape: Oval Cabochon (Excellent dome height) Body Tone: N8 (Light/White) Brightness: B3-B4 (Bright and visible in natural daylight) Pattern: Pinfire / Rolling Flash with significant Red/Orange fire. Condition: Excellent. No crazing, cracks, or surface pits. High professional polish. Price: $500 (Or best reasonable offer) Shipping: $15 (USPS Priority Mail, Insured, with Signature Confirmation required). Payment: PayPal Goods & Services only. Note: As this is a private sale of an estate item, all sales are final. Please feel free to reach out to me directly at keva.crpa@gmail.com

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.

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
