Ethical Craftsmanship & Uncompromising Quality

Our diamonds come to life by reproducing the incredible heat and pressure that form diamonds underground.

Lab-grown diamonds are chemically, physically, and optically indistinguishable from mined diamonds, even under a 10X microscope. Their quality is assessed through the same four characteristics: color, cut, clarity, and carat (the 4C’s).

    The process of growing diamonds above ground is in large part left to chance and serendipity - one cannot choose the size, shape, and quality of the diamond that will result from pressurized heat and carbon.


    Each lab-grown diamond has its own unique fingerprint, and just like with mined stones, very few are gem-grade. The rarest of all are the flawless, completely colorless D-grade diamonds that are used in Or & Elle pieces.


    We accept 0.01% of lab-grown diamonds. By dint of our 100 years of experience in the diamond capital of the world, our Atelier has the savoir-faire to source and set a supremely rare edit of the world’s most exceptional diamonds.

About our diamonds


Carat is the unit of measurement for diamond weight. Carat weight alone does not determine how large or small a stone looks. Cut and shape influence the appearance of size as well.

Carat Carat

The rarest and most ideal diamonds are colorless, or grade D. As diamonds show increase hues of yellow, their color grade decreases. Most jewelers use grade I-J diamonds and lower. We only use D color diamonds.

Color Color

Diamonds may have imperfections called inclusions. The fewer and smaller, the clearer the diamond. Most jewelers sell SI stones; we only use IF/VVS.

Clarity Clarity

Cut is the most important determinant of sparkle and the only element determined by craftsmanship rather than by chance. Our skilled artisans guarantee ideally cut angles for maximum brilliance.

About our diamonds

A round diamond scintillates from 57 facets. This shape is as timeless as it is brilliant.

Round Round

Ovals cover a larger surface area than other cuts of comparable carat weight. The length and width of two ovals with the same carat weight can vary. Color is paramount for this shape.

Oval Oval

Pears, also known as teardrop diamonds, are among the most unique cuts. They have the brilliance of a round and the elongating effect of a marquise.

Pear Pear

Emerald is a regal, step-cut diamond, that gives the appearance of a hall of mirrors. Clarity is paramount for this shape.

Emerald Emerald

Marquise cuts are softly curved diamonds that point at both ends. They have the largest surface area per unit of carat weight.
