Do you have all finger sizes?

Yes. On the site we offer you "standard" sizes but our workshops adapt to all finger sizes. From the smallest to the largest, our jewelry is made to measure, so don't worry, you will definitely find what you're looking for.

Do not hesitate to consult our teams for more information.

What metal do you use?

All of our Jewelry Collection, diamond solitaires, wedding rings, earrings, or necklaces are made of 18 karat gold 750/1000 (75% pure gold) and Platinum 950/1000 (95% pure platinum).

Pure 24 karat gold is too soft and therefore not suitable for jewelry production. That's why we use an alloy with other metals.

For example, 18K white gold is a mixture with 25% silver and palladium.

Gold is naturally yellow, that's why we use other metals like silver and palladium to make it white. Note that each of our pieces of jewelry made in white gold is coated with a layer of rhodium to give it an even whiter and brighter color. We recommend for the maintenance of your jewelry to apply a rhodium polish to restore its brightness and whiteness.

Platinum is not an alloy but a 95% raw material, that's why we use the term 950/1000 when talking about the Platinum jewelry in our CELINNI collection.
