Our stones and metals are sourced only from suppliers who guarantee they are conflict-free.

Matte Gold: Use a very soft 100% cotton cloth and/or a soft toothbrush with warm water and a gentle soap.

We stand by our work and have taken great care to make a solid, long lasting beautiful piece of jewelry. That said, jewelry is not indestructible and extra care should be taken to ensure that your cherished piece remains in great condition for years to come. Stones and metal can become loose, chip, or crack through prolonged heat/cold exposure, contact with harsh chemicals, certain perfumes/lotions, chlorine, or knocking up against another hard surface (e.g. don't wear it while sledding or in the hot tub...); basically, when in doubt, remove your jewelry.
