Frequently asked.

Chemically, physically and optically identical to a mined diamond — the only difference is origin. A lab-grown diamond is grown in a controlled lab environment over a few weeks, rather than formed underground over millions of years.

Solid 925 sterling silver, finished with luxury-grade rhodium plating for a bright, tarnish-resistant white-metal finish. The rhodium layer is what gives the lasting shine — it's a finish, not a base metal substitute.

The rhodium plating slows tarnishing significantly, but like all fine silver jewellery, it will dull gradually with wear. Store your piece in its pouch when not worn, keep it away from perfume, chlorine and moisture, and wipe with a soft cloth after wear.

Store each piece separately in its pouch to avoid scratching. Avoid perfume, chlorine and harsh chemicals — put jewellery on last, take it off first.
