Holly Christian:

Sea Glass Jewelry

All my beach glass and sea glass is the real thing, tumbled smooth by waves and sand, never by machine. . Sea glass has a naturally frosty
surface. If it becomes too dry looking, rub on a bit of mineral oil to make it glow.

Sterling

Sterling jewelry can always be brightened
with a silver polishing cloth.

Copper Jewelry

Copper discolors at a different rate depending
on a variety of factors. When I wear my copper ring
and use lots of lotions or wear rubber gloves it discolors
very quickly. My skinny copper cuff bracelets darken more slowly.
Sometimes I like the darkened copper and sometimes I don't.
Copper can be cleaned with a polishing cloth or by dipping in vinegar.
