If you love green but not the fragility, green sapphire is the answer the trade rarely advertises. It is corundum, so it reaches 9 on the Mohs scale and shrugs off daily wear, while emerald, at roughly 7.5 to 8, is almost always cracked and oiled to hide it. Our green sapphires are sourced directly in Sri Lanka and certified by an independent gem laboratory.
Emerald gets the spotlight, but it comes with caveats most shops gloss over. Per GIA, almost all emeralds contain eye-visible inclusions, and the fractures that reach the surface are routinely filled with oil or resin to hide them. Green sapphire skips all of that. It is the same species as blue sapphire and ruby, which means a hardness of 9, far better toughness, and usually nothing more than heat applied to it, if anything. You trade a touch of emerald's vivid grass-green for a stone you can actually wear without babying it.
Green sapphire owes its color to iron, mixed with a blue component caused by an iron and titanium interaction inside the crystal, per GIA. That is why green sapphire often carries teal and blue-green undertones rather than the pure green of emerald. We see this as a feature, not a flaw. A green sapphire with a teal lean is one of the most distinctive, hard-to-fake colors in the corundum family.
Green sapphire ranges from yellow-green through blue-green, in tones from light to quite dark. The trade has long called the duller stones khaki or olive, which is fair for low-saturation material with heavy zoning. The ones worth owning have even color and enough saturation to read clearly as green or teal-green in the hand. We grade for that and pass on the muddy stones, which is why the selection here is small rather than padded.
Because green sapphire never got the marketing emerald did, demand stays modest and prices stay reasonable. Fine untreated stones with vivid color can climb, but most green sapphire offers genuine sapphire durability for far less than fine emerald or fine blue sapphire. Each stone below is a single piece with its own independent laboratory report. Browse the loose green sapphires.
