Why collectors buyfrom the source

  • Authentic Ceylon origin

    Every stone is bought at the source — Ratnapura, Elahera, Balangoda, Meetiyagoda — and its origin is stated on the report, not inferred.

  • Independently certified

    GIA, GRS, SSEF, Gübelin or the NGJA. Treatment status is disclosed in full, including traditional heating, without exception.

  • Ethically sourced

    Sri Lanka's gem industry is artisanal and licensed by the state. We buy from families and small syndicates we have worked with for decades.

  • Expert selection

    Stones are graded in person under standard light. Anything with a window, a bow-tie or uneven colour never reaches the collection.

  • Worldwide delivery

    Fully insured courier to over sixty countries, with export documentation and a fourteen-day return on every purchase.

  • “Rare. Authentic. Timeless. Ceylon.”

    The house standard, since the first parcel

Gemstone guide

Understanding the stones

A short, honest primer on the species Ceylon is known for — what creates the colour, what makes a stone rare, and what to ask before you buy.

Corundum · Mohs 9

Sapphire

Ceylon sapphire is the reference standard of the trade. Lower iron content than most origins gives the island's stones a brightness that survives low light, and the classic tones — royal blue, cornflower, golden yellow — are named after Ceylon material.

Corundum · The lotus colour

Padparadscha

A sapphire that holds pink and orange at the same time, named for the lotus blossom at sunrise. Laboratories apply the term narrowly, and Sri Lanka is its classical source — no other origin produces it consistently.

Corundum · Chromium red

Ruby

Ruby and sapphire are the same mineral; chromium makes the difference. Ceylon rubies run brighter and slightly pinker than Burmese stones, and unheated examples above two carats are genuinely scarce.

Chrysoberyl · Colour change

Alexandrite

Green in daylight, red under candlelight. The change is caused by chromium in a lattice that transmits two windows of the spectrum, and the value of a stone is set by how complete that change is.
