Sri Lanka & Madagascar · Est. in the vault, opening soon
Something rare
is being unearthed.
GemOasis sources, evaluates and certifies natural rubies, sapphires, spinels and colour‑change gemstones — drawn primarily from the mines of Sri Lanka and Madagascar. Every stone leaving our vault carries certification from GIA, GRS or AIGS. The showroom is still being cut. The stones are already here.
A true colour-change stone shifts hue with the light source. It's the same phenomenon a spinel or alexandrite performs on your hand — GemOasis grades and discloses it on every certificate.
Where the stones come from
Sri Lanka
The island that gave the world the Ceylon sapphire. Our stones are drawn from the traditional mining belts of Ratnapura and Elahera, evaluated a short drive from where they're pulled from the earth.
Madagascar
A newer frontier for ruby, sapphire and spinel, sourced from Ilakaka and Andilamena through partners we've vetted directly for fair and ethical practice.
GemOasis (Pvt) Ltd is engaged in the sourcing, evaluation and sale of natural, ethically sourced gemstones — rubies, sapphires, spinels and colour-change stones — primarily drawn from Sri Lanka and Madagascar. Every stone we offer is accompanied by certification from an internationally recognised gemological laboratory: GIA, GRS or AIGS.
