Ratnapura · Since 1982
Three generations of master gemologists sourcing ethically mined sapphires, rubies, and rare cat's eye direct from the legendary mines of Sri Lanka.
The Collection
Cornflower blue, padparadscha, yellow and pink — the spectrum that built Sri Lanka's reputation across centuries.
Pigeon-blood reds and rich raspberry hues, hand-selected and certified for clarity and natural origin.
The phenomenal stone of kings — sharp chatoyancy and golden honey tones, found nowhere finer than Sri Lanka.
Heritage
Founded in Ratnapura — the City of Gems — Gem Crown International has spent four decades building direct relationships with miners, cutters, and master lapidaries across Sri Lanka.
Every stone we offer is mined responsibly, cut in-house, and accompanied by certification from internationally recognised gemological laboratories.
