Green sapphire is corundum colored primarily by iron — the same mineral as ruby and blue sapphire, but in a cool, natural green that ranges from soft mint through vivid mid-green to deep forest. It is the most underrated color in the sapphire family: genuinely rare, strikingly beautiful, and priced well below what comparable blue or pink sapphires command. At Mohs 9, green sapphire is dramatically harder and tougher than emerald (Mohs 7.5–8), never needs oiling or retreatment, and offers eye-clean clarity as the standard — making it the most practical green gemstone for daily-wear rings.
Why our green sapphires
Our green sapphires are sourced from Sri Lanka, where iron-rich corundum produces clean, bright greens with excellent transparency. The majority are unheated — green sapphire rarely benefits from heat treatment, and many stones show their finest color in their natural state. Every stone is individually photographed under standardized lighting, and treatment status is disclosed on every product page.
Green sapphire as an emerald alternative
If you love green but want a stone that can handle daily wear without special care, green sapphire is the answer. Unlike emerald, which is fracture-prone, requires oiling, and must be re-oiled every 5–10 years, green sapphire is scratch-resistant, chip-resistant, safe for ultrasonic cleaning, and completely maintenance-free. The trade-off is color intensity — emerald's chromium green is more vivid than sapphire's iron green. But for wearability, durability, and value, green sapphire wins decisively.

How to choose a green sapphire
Hue. Green sapphire ranges from pale mint and seafoam through vivid grass green to deep forest. The most valued greens show strong saturation without going so dark that they lose transparency under indoor lighting.
Saturation. Vivid mid-tone greens command the highest prices. Stones with yellowish or brownish secondary hues are less prized; a clean, pure green reads most powerfully.
Cut. Oval and cushion are the most popular for engagement rings. Emerald cuts showcase green sapphire's clarity beautifully — and unlike actual emerald, green sapphire has the clarity to handle step facets without revealing problematic inclusions.
Carat. Green sapphires offer outstanding value. Sub-carat stones start under $200. One-carat unheated greens with vivid saturation typically range from $300 to $1,500 per carat — a fraction of what comparable blue or pink sapphires cost.
