Emerald by day.
Ruby by night.
One stone. The light decides what you see.
So we hand you the light.
Certified stones, shown under every light, sold in private.
The house rule
A photograph is one light, chosen by the seller.
Every listing you have ever read carries the same quiet line. Colour may differ under different lighting. It is true, and the trade has been living inside that sentence for a century. A stone is photographed under the one light that flatters it, and that is the only light you are ever shown. We do the opposite. Take the light and move it yourself.
Light 6500 K
Daylight
Press and hold the button to warm the light on the stone from daylight to candlelight.
That is the same stone. Only the light changed.
Certified, not described
The one reading no light can flatter.
A certificate is the only part of a stone that does not change with the lighting. Ours travel with the stone, from the laboratory, in the laboratory's own words.

The collection
Three ways in.
How it works
Three steps, no showroom.
01
You tell us what you are looking for
A stone, a budget, a shape, or only a feeling. Nothing is listed publicly until you ask.
02
We send it under every light
Filmed under daylight, under warm indoor light, and under the laboratory's own. The certificate arrives with it.
03
You decide, in private
Insured, tracked, signed for. No part of this appears anywhere public.
Before you ask
The questions people actually ask.
How do I know the stone matches its certificate?
Every certificate carries a number you can check with the laboratory yourself, without us. GIA, IGI and GRS each publish a public verification page. We would rather you checked.
Can I see it under my own light first?
Yes. That is the whole point of this house. Every stone is filmed under daylight, under warm indoor light, and under the laboratory's standard light, and all three reach you before you commit to anything.
What if it does not look like the photographs?
Then it goes back. The stone travels insured both ways, and the decision is yours after you have held it, not before.
How is something worth this much shipped?
Fully insured, tracked, signature on delivery, value declared and covered end to end. The hesitation you feel handing something like this to a courier is rational. So we take it off your side entirely.
Will it hold its value?
A certificate from a recognised laboratory is what makes a stone insurable and resellable at all. That is the honest answer. What any stone is worth in ten years is not something anyone can promise you, and we will not.
Is any of this public?
No. No listing, no auction record, no name on anything. Discretion is not a service this house charges for. It is how it works.
The only ask on this page
