Loose stone, GIA certified Available
The house
We supply the stone, not the piece.
Valmer Carat is a French trading house specialising in natural colour diamonds. We assist jewellers, workshops and private clients in acquiring the stone that will carry their project, taking into account the hue desired, the intensity, the shape, the weight and the budget available.
Our selection spans the spectrum of natural colours — yellows, pinks, oranges, and rarer hues besides. Where a stone does not appear among those we hold, we undertake to obtain it for you: you need only specify what it must be.
We offer loose stones only, to the exclusion of any mounted piece; this is the specialisation of the trade, and it allows us to devote our full attention to the stone itself. Each is certified by the Gemological Institute of America and filmed before any transaction, so that you may judge it as it is.
Valmer Carat brings together natural colour diamonds, loose and GIA certified, for jewellers and private clients alike. Our role is to assemble, for each project, the stones that suit it, and to accompany you through to the final choice.
Our storyWhat to know
On a colour diamond, hue and intensity account for most of the price. Weight comes far behind. A small, intensely coloured stone outranks a large pale one.
The GIA places every stone on seven grades, from Faint to Fancy Vivid. The laboratory report alone is authoritative.
No two colour diamonds are alike.
We come back with the list of available stones, or with questions.
Selection
Every stone is filmed. Video shows what a photograph cannot: the way the colour moves inside the stone.
This selection changes. Other hues, other shapes and other sizes can be obtained on request, under the same certification conditions.
Before the setting Loose stone
How we work
Whether you are a private client or a professional, the approach remains the same. You set out your project and the budget you are working with, then we send you the list of stones currently available, each with its hue, intensity, shape and weight; we then narrow it down with you to those that genuinely answer what you are after.
You describe the piece, the hue you have in mind and the budget you are working with.
You receive the stones currently available, with the video and GIA report for each.
If no stone on the list is right, our partners allow us to obtain the one that matches.
The stone leaves with its report. Handed over in person by appointment, or shipped insured.
The report
Every stone we present comes with its report from the Gemological Institute of America. The laboratory records the natural origin of the colour, the hue, the intensity, the weight and the cut. We present no stone without that document.
