The finest rubies are defined by a rare harmony of colour, origin, and natural beauty. Burma retains exceptional prestige, long associated with some of the world's most revered rubies, while Mozambique has also yielded rare and important gemstones of remarkable distinction. Trace amounts of chromium give ruby its unmistakable red colour and almost incandescent presence. 

A ruby's worth is shaped by colour, origin, treatment, and brilliance. Fine unheated stones remain especially prized and highly sought-after, admired for preserving the gemstone in its most natural and untouched state. Compared to other gemstones, fine rubies are exceptionally scarce, particularly within top-tier unheated categories.
