Gemstone Varieties: A Spectrum of Beauty
Your comprehensive guide to gemstone identification, properties, origins, and varieties — from the common to the extraordinarily rare.
Precious & Semi-Precious Gemstones
Gemfame is a prominent provider of genuine quality precious and semi-precious gemstones, offering an extensive multinational collection sourced from the world's finest mines. Our collection emphasizes natural, untreated stones at honest and transparent prices.
Gemstones are broadly divided into two categories — precious and semi-precious — though this distinction is largely traditional and commercial rather than mineralogical. All gemstones are minerals (or occasionally organic materials) that have been cut and polished for use in jewellery and ornamentation.
The Four Classical Precious Gemstones
Ruby (Manik)
The King of Gemstones. A red variety of corundum coloured by chromium. Mined primarily in Myanmar, Sri Lanka, and Thailand.
Sapphire (Neelam / Pukhraj)
A corundum variety occurring in blue, yellow, pink, and many other colours. Sri Lanka and Kashmir produce the finest specimens.
Emerald (Panna)
A green variety of beryl coloured by chromium and vanadium. Colombia's Muzo, Chivor, and Coscuez mines are legendary sources.
Diamond
Pure carbon crystallised in the isometric system. The hardest natural substance (Mohs 10), prized for brilliance and fire.
