VARIETIES
What We Can Source
Through our custom sourcing service, we access a broad spectrum of coloured gemstones from trusted suppliers across the world's major gem-producing regions.

Emeralds
Colombia · Zambia
Vivid green to deep bluish-green. Colombian stones are prized for pure green saturation; Zambian emeralds offer a distinctive blue-green depth. Minor to moderate jardin inclusions are industry-standard and expected. Untreated and minor-oiled options available on request.

Tourmaline
Brazil · Mozambique
One of the most colour-diverse gemstone families. Paraiba tourmaline from Brazil commands premium pricing for its neon blue-green. Rubellite (vivid red-pink), indicolite (blue), and chrome green are also available. Mozambique Paraiba offers an accessible alternative.

Spinel
Myanmar · Tanzania
A rising star in the fine gemstone market — naturally untreated, no heat treatment needed or applied. Available in red, hot pink, cobalt blue, lavender, and grey. Mahenge hot pink and Burmese red spinel are particularly sought-after by collectors.

Alexandrite
Rare · Color-Change
The ultimate colour-change gemstone — vivid green in daylight, red-purple under incandescent light. Genuinely rare; fine alexandrite above 1 carat commands exceptional pricing. Available on a sourcing basis with independent laboratory certification confirming the colour-change effect.
Additional gemstones available on request: tsavorite garnet, tanzanite, aquamarine, morganite, rhodolite garnet, and more.
