Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 1.46 carat olive green sapphire in a cushion cut, from Madagascar, completely unheated. Olive green is the warmer, more golden end of the green sapphire spectrum — a hue that reads with yellow-green undertones rather than the cool mint of lighter greens. In a cushion cut, the rounded corners trap light and deepen the olive saturation, producing the characteristic warm glow that makes this color popular for vintage-inspired settings and yellow gold work.
Expert Opinion
Ahmed Shareek's Assessment
"Olive-green is one of the more overlooked colors in the sapphire family — most buyers default to blue, and that lack of demand ironically makes genuinely well-colored olive stones harder to source than the price would suggest. What I look for is warmth and evenness of tone, and this 1.46 ct stone has both, with no heat treatment involved. An unheated stone in this color and size at this clarity is not something we come across often."
Rarity Analysis
Olive-green sapphire sits well outside the mainstream of sapphire buying, and several factors combine to make this particular stone an uncommon find.
-
Color: green/olive-green sapphire is one of the least common sapphire colors in typical market supply
-
Size: at 1.46 carats, this stone is a comfortable centerpiece size for a color that is most often seen well under 1 carat
-
Treatment: the large majority of sapphires on the market are heat-treated to improve color; this stone is unheated, which is a meaningfully rarer proposition in any sapphire color
-
Clarity: eye-clean clarity in an unheated stone of this size and color adds a further point of scarcity, since untreated stones more often show visible inclusions
-
Documentation: this stone is offered without a third-party gemological laboratory report; that is disclosed transparently here so buyers can weigh it appropriately rather than assume a certification exists
-
Combined effect: an uncommon color, solid carat weight, unheated status, and eye-clean clarity together make this a genuinely distinctive stone, even without a formal lab report attached
Buying Guidance
A few practical points to weigh before purchasing this stone.
-
Color Preference: olive green reads warmest in yellow gold; if you prefer a cooler-toned green, view the stone under a few different lighting conditions before committing
-
Certification: this sapphire is not accompanied by a third-party gemological report, so the color, treatment, and clarity representations here rely on Crescent Gems' in-house assessment rather than an independent lab — factor that into your decision, and reach out with any questions before you buy
-
Setting Considerations: the cushion cut and 1.46 ct size work well across a range of ring styles, from vintage-inspired halos to simple solitaires
-
Long-Term Value: unheated stones in uncommon colors tend to hold collector interest better than heated, common-color stones of similar size
-

Why Choose this 1.46 ct Unheated Olive Green Sapphire?
Olive green sapphire is less commercially common than blue or pink, which is exactly what makes it appealing for buyers who want a distinctive stone rather than the conventional choice. Madagascar origin adds the premium of documented provenance in a color that rarely carries formal lab reports. At 1.46 carats unheated, the size-treatment combination is stronger than most olive greens available in the sub-1-carat commercial range.
