Rubies of true red carried on certified diamonds — from a single drop to suites of a hundred carats. Each piece documented, each price stated plainly.












Of the three great coloured stones, the ruby argues loudest against the diamond — a saturated red that gives no ground to the white fire beside it. A necklace is where the argument becomes a composition: calibré-cut rubies traced in brilliant diamonds, heart-shaped and oval stones carried on graduated lines, cabochon rubies of retro suites, and chokers where ruby and diamond alternate the whole way round. Every piece in this collection is held in the House's own vault, documented, and priced at one transparent figure.
From focused single-drop pendants to important suites priced in the millions — rubies carry the highest per-carat prices of any coloured stone, and the necklace form multiplies the count. Colour is the whole game: the saturated red the trade calls pigeon's blood commands multiples over lighter or browner stones of the same weight, and an unheated ruby of fine colour is rarer than a comparable sapphire or emerald. Each listing carries the single, honest price, and an advisor will explain exactly what colour, origin and treatment mean for any stone's figure.
Colour before everything: a pure to slightly purplish red, saturated without going dark, alive in daylight and lamplight both. Then treatment — heating is traditional and disclosed on the certificate; an unheated stone of comparable colour carries a serious premium. Then origin, which the laboratory can generally determine and the certificate states. The diamonds around the ruby are graded exactly as our white stones are, and every certificate is shown before any commitment.
