Each is individually created by hand from 14 karat yellow gold fill, rose gold fill and sterling silver. "Fill" means gold- filled with an alloy of pure base metals (copper & brass). The gold is durable enough to withstand a 1400° flame, hammering and polishing. It will not degrade or rub off with wear unlike gold plate or vermeil. You never have to take these off.
If you like minimalist adornment and understated stacking rings, these are your match. Wear one or stack them all the way up.
