Blue diamond ring

The blue diamond comes as a solitaire on the Andrea Ring, as a pear on the Loop, as an Asscher cut on the Faubourg 1925, as a marquise on the Mme La Marquise or on the Christine. The Baby and Baby One rings from the Faubourg 1925 collection make it a slender ring, worn alone or stacked.

Blue diamond engagement ring

A blue diamond changes the engagement ring without changing its promise: it is a real diamond, as hard and as brilliant as a white one. On white gold, it makes a cool, luminous ring; on yellow gold, an older, almost royal contrast.

Blue diamond jewellery

Our earrings, necklaces and bracelets are set with the same stones, to build a matching set or add a touch of colour to a piece you already wear.

Lab grown blue diamond: what you are buying

The Hope diamond, on display in Washington, made the blue diamond a legendary stone. A lab grown blue diamond is crystallised carbon, just like a mined diamond: same composition, same hardness, same sparkle. Only its origin changes, and with it, its price.

Gold, silver or vermeil

Every piece comes in the same design in recycled 18k yellow or white gold, rhodium-plated 925 silver and vermeil. Blue diamond rings from €190, free delivery across Europe. Discover our pink, green and yellow diamonds too.

Blue, without the mine

A diamond's blue comes from boron trapped in its crystal structure. One atom in a million. That is all that separates a colourless diamond from the Bleu de France, stolen during the Revolution, recut, and known today as the Hope.

Those stones sit behind glass. Ours sit on hands. Grown in a laboratory, never mined, our blue diamond keeps the hardness of 10 and the refractive index of a diamond.

Three metals: solid 925 silver, vermeil, recycled 18 carat gold. From 190 € to 5,990 €.

Introducing

Blue diamond or sapphire: light does not behave the same way

A sapphire is a corundum: hardness 9, refractive index 1.77. It absorbs. A deep, velvet blue that keeps the light to itself.

A blue diamond is pure carbon: hardness 10, index 2.42. It gives the light back. Lighter, more mobile, it shifts with the angle.

On a ring worn every day, ten years is long enough to see the difference.

Introducing

Three cuts, three ways to wear blue

Faubourg 1925 is the house's Art Deco line: brilliant cut on the Baby One, 0.70 carat Asscher on the statement pieces. The blue stacks up in layers.

Mme La Marquise takes the marquise cut, stretched along the finger. The blue runs out towards the points.

Loop works the pear, a drop held in the curve of the band.

Solid 925 silver is the metal of blue: same family of cold, the stone melts into it. Recycled 18 carat gold creates the warm and cold contrast of classic haute joaillerie.
