Henri Moissan found the first crystals in 1893, inside a meteorite crater in Arizona. Natural moissanite is rarer than diamond, which is why today's stone is grown in laboratory conditions, to the same crystal structure, with greater consistency than anything pulled from the earth. Refractive index 2.65. Mohs hardness 9.25. It does not dull or cloud over time. We chose it because it is the finest stone available for the price we charge.

No. Our pieces are 925 sterling silver sealed with a rhodium finish, or gold vermeil: a thick layer of gold over sterling silver. The finish keeps the metal underneath away from your skin.

Warm water, mild soap, a soft brush. Rinse well and dry with a lint-free cloth. Store in its pouch when not worn. Remove before exercise, swimming or contact with chemicals. Moissanite itself does not degrade: with basic care, the stone will look the same in twenty years.

We make it for you. Every piece is produced in limited quantities; if your size is not immediately available, it is made to order and reaches you within 21 days.

Some pieces can be adapted: a different stone size, a specific metal, a detail that is yours alone. Write to us with what you have in mind.

Use the Ring Size Guide: measure on screen with a bank card and a ring you own, or measure your finger with a strip of paper and compare it to the chart. If you are between sizes, we recommend the larger one.
