Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 1.18 carat peach sapphire in an oval cut, completely unheated and documented on AGCL Report #M260131. Peach sapphire is natural corundum in the warm blush-orange range — a tone that reads with romantic warmth in daylight and rich amber under incandescent light. Unheated peach sapphire preserves the delicate orange-pink balance that heat treatment can shift toward pure orange or pure pink.
Expert Opinion
Ahmed Shareek's Assessment
"Unheated peach sapphires are the ones that get me most excited, because heat treatment is so often used to push corundum toward a pure pink or a pure orange — finding one that kept its natural pink-orange balance without ever seeing a furnace is genuinely uncommon. This 1.18 ct oval has that soft, romantic warmth exactly where nature left it, and the AGCL documentation gives buyers real confidence in what they're getting."
Rarity Analysis
A handful of factors combine to make this particular peach sapphire meaningfully scarcer than typical peach-colored corundum on the market:
-
Color: a balanced, delicate orange-pink tone that has not been shifted or deepened by heat is genuinely scarce — most commercial peach sapphire has been heat treated to reach or stabilize this color
-
Size: at 1.18 ct, this oval sits in a wearable yet still substantial size bracket for a fine natural colored gemstone in a ring or pendant
-
Treatment: unheated peach sapphire is less common — heat treatment often disrupts peach's delicate pink-orange balance
-
Clarity: Loupe Clean is a strong grade
-
Documentation: backed by AGCL Report #M260131; origin is Sri Lanka (Ceylon) (store's own assessment; not addressed by the AGCL report)
-
Combined effect: the pairing of natural, unshifted color, no heat treatment, loupe-clean clarity, and third-party documentation places this stone well outside the range of typical commercial peach sapphire
Buying Guidance
A few things worth knowing before choosing a peach sapphire like this one:
-
Verify treatment disclosure: always confirm in writing whether a colored stone is heated or unheated — this one is documented unheated on AGCL Report #M260131
-
Compare color in different light: peach sapphire shifts subtly between daylight and incandescent light, so view the stone (or request video) in both before deciding
-
Understand what "store's own assessment" means: the AGCL report does not address origin, so the Sri Lanka (Ceylon) origin listed here reflects Crescent Gems' own evaluation rather than a lab-certified origin call
-
Match the setting to the stone: warm-toned metals such as rose or yellow gold tend to complement peach sapphire's blush-orange hue
-
Try Before You Buy: request additional photos or video in different lighting before committing to a fine colored gemstone purchase
