A designer of high-end costume jewelry, we use natural stones (amethyst, turquoise, carnelian, moonstone, labradorite, aventurine, pyrite, etc.), river pearls, glass paste, old medals in common metal, brass and white metal composed of 75% pure silver and 25% brass.
Our white metal containing less than 80% pure silver, it is not solid silver, it is defined as a common metal and not as a precious metal.
This is why there is no hallmark on our jewelry and our jewelry is costume jewelry.

Some of our jewelry is made of brass gilded less than 1 micron with 999/1000 gold.

The good advice:

To preserve the shine of your jewelry, we recommend that you maintain it by regularly using a chamois and storing it in the original pouch received when you ordered. Avoid sleeping with it. Take care of your ARKEOLOGY costume jewelry by avoiding direct contact with chemicals, soap, showers, and swimming pools. Avoid spraying or wearing perfume on skin in direct contact with your jewelry.
