pink diamonds

Pinks are the only diamonds we carry with treated colour. We say so first, because it is the most important thing to know about them.

The stone is mined from the earth like any natural diamond, and receives its pink colour afterwards, with human help. The treatment is permanent: the colour stays with the stone for good.

colour without an impurity

Nitrogen gives a yellow diamond its colour, boron a blue one. A pink has no such impurity: its colour appears when the crystal, deep underground, is squeezed under pressure and its lattice shifts slightly. That is why pink often lies in the stone in bands — traces of that shift. Why some crystals turn pink from it and others brown, no one fully knows.

treatment

colour with a human hand

A treated stone is mined from the earth like any natural diamond, but it received its noble pink colour with the help of people. Very few stones come out with a beautiful colour: after treatment they often turn dark burgundy, orange or pale. Truly noble pinks among them are rare, and their shades vary — from cool, almost lilac, to warm with a hint of peach.

GIA

written on the stone itself

A GIA report states the treatment plainly: the origin of colour reads Treated. And the girdle of each of our pinks is laser-inscribed TREATED COLOR next to the report number — the truth about the colour stays on the stone itself, whoever it ends up with.

the scale

how to read the colour

GIA describes pink by two measures: hue and saturation. Hue — pink, purplish pink, orangy pink; saturation — from Faint to Fancy Vivid, and Fancy Deep and Fancy Dark for darker stones. The brighter and purer the pink, the rarer the stone.

pink is chosen with the eyes

Shade, cut, play of light, size, the way the stone looks on the hand — that is what the choice is made of. The report tells you where the colour comes from; whether the stone is yours is for your eyes to decide. A pink can only be bought in person. We hunt for them all over the world and view them at the producers' offices — and we look forward to showing you the collection in our showroom.

questions

What does a "treated" pink diamond mean?

It is a natural diamond: mined from the earth, it received its pink colour after mining, with human help. The treatment is permanent: the colour stays for good. The GIA report states it (Treated), and TREATED COLOR is laser-inscribed on the girdle.

Why do two diamonds of the same carat weight look different in size?

A carat is a unit of weight, not size. Part of the weight can sit in the depth of the stone, so it looks smaller from above. We choose stones that face up larger than the market average for their carat weight.

Can you choose a diamond by its GIA report alone?

A report describes colour, clarity and proportions honestly, but not the stone's play of light: windows, colour dead spots and uneven facets show only to the eye, and a video can hide them. That is why we view every stone in person before buying — and suggest you do the same.

Do I need to pay a deposit?

No. You decide to buy only after seeing the stone in person. This applies to the large stones we bring in to order as well.

Which stones are in stock in Moscow?

Diamonds: always in stock from 1 to 5 carats, with a choice of colour and clarity, so you can compare and see what speaks to you. Larger diamonds are rare: some are in the catalogue, others we bring in to order, and they are often sold before they arrive. Emeralds have their own scale: from stones for studs to collector stones of tens of carats; see the catalogue for what is in stock now.

Can I just have the cheapest stone of a given carat weight?

No — we will decline if all you want is the cheapest: such a stone is almost always a poor one, and we would rather not be embarrassed by our client's stone later. Nor does the best stone have to be the most expensive: the price should match the market.

Why not buy cheaper while travelling abroad?

You can. But if the stone turns out not to be what you were sold, there is no one to go back to, and you will have to explain the piece at customs. Our pieces are imported officially and registered in the Russian state precious-metals system (GIIS DMDK), our showroom has a permanent address, and we are a second-generation jewellery business.

How do I check a GIA report?

The report number is on each piece's page and links to the GIA database (gia.edu). In the showroom we will show you the report itself and, together with you, look at the number inscribed on the stone's girdle under an electronic microscope.

The price is in US dollars — how do I pay?

Within Russia, payment is made only in roubles, converted at Sberbank's dollar selling rate on the day of purchase.
