Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 0.57 carat pink sapphire in an oval cut, completely unheated, documented on AGCL Report #M262737. Pink sapphire is natural corundum colored by trace chromium — the same element responsible for red in ruby, but in lower concentrations. At 0.57 carats in an oval, this is a practical earring and small pendant scale in a warm, romantic color. Unheated status means the color is entirely natural — no thermal treatment has been used to modify or enhance this sapphire's hue.
Expert Opinion
Ahmed Shareek's Assessment
"The oval cut on this 0.57 ct stone does real work — pink sapphire can look washed out face-up in the wrong cut, but the oval's broad table keeps the color even and visible at this weight. Ceylon origin and unheated status together are the combination collectors specifically look for in pink sapphire."
Rarity Analysis
A few factors combine to make this stone worth a closer look:
-
Color: Natural pink caused by trace chromium — the same element that colors ruby, present here in lower concentration — unmodified by heat.
-
Size: 0.57 ct is a practical earring and pendant weight; unheated stones in this color-weight combination are offered less often than heated equivalents.
-
Treatment: AGCL Report #M262737 confirms no indication of heating.
-
Cut: The oval's larger face-up area relative to carat weight displays color efficiently even at sub-carat size.
-
Documentation: Independently lab-certified with weight, dimensions, and treatment status on record.
-
Combined effect: unheated Ceylon pink sapphire, certified, at an earring-ready weight, is a narrower slice of the market than heated pink sapphire generally.
