WHAT MAKES A BLUE SAPPHIRE BLUE?
Blue sapphires get their color from trace amounts of iron and titanium within the corundum crystal structure. The interaction between these elements absorbs certain wavelengths of light, leaving the blue we see.
The finest blue sapphires show a pure, vivid blue without secondary green or gray tones. Color saturation should be strong but not so dark that it appears black.
Royal Blue — Intense, vivid blue with excellent saturation. The benchmark for fine blue sapphires.
Cornflower Blue — A softer, velvety blue with a slight violet modifier. Associated with Kashmir sapphires.
Padparadscha — Not blue! A rare pink-orange variety. View padparadscha →
BLUE SAPPHIRE ORIGINS
KASHMIR
The holy grail. Velvety cornflower blue with a unique "sleepy" quality. Virtually no new production since the 1880s. The most valuable blue sapphires in the world.
CEYLON
Classic medium-toned blues with excellent brilliance. The most consistent source for fine blue sapphires. Strong market liquidity.
BURMA (MYANMAR)
Rich, saturated royal blues. Often compared to Kashmir for color intensity. Increasingly rare and valuable.
Royal Blue Grade
The GRS "Royal Blue" designation is the most commercially significant colour grade in sapphires. Only ~5% qualify — unheated royal blue commands 3–8× the price of heated equivalents.
Cornflower Blue Grade
The GRS "Cornflower Blue" designation is the benchmark colour for Ceylon sapphires — medium-toned, vivid blue with slight violet. Unheated cornflower blue Ceylon stones trade at $3,000–$25,000/ct.

Blue sapphires have been prized for millennia. Unlike fashion-driven markets, demand for fine blue sapphires is consistent across cultures and generations. Top-quality stones have appreciated 5-10% annually over the past decades.
Rarity Increasing
Historic deposits in Kashmir are depleted. Burma faces political instability. Even Ceylon's production of top-quality material is declining. Supply constraints support long-term value.
