Nallik's amazonite/quartz necklace (at left); I added it to a pinterest board months ago.Of course, at $169, it's way out of my price range. I recently finished (and mailed to a girlfriend) a simple amythest necklace inspired by Nallik's stone necklace, though I'd still like to go hunt up a pair of crystals, match them to each other, and achieve the colour-blocking effect of Nallik's original.
The top of the necklace is just a brass plate, shaped to fit the amythest crystal and adhered with an epoxy made by gorilla glue. A brass chain (Nallik's is gold-plated) and simple clasp finish off the look. I used a 24" long chain for mine.
Simple, but so pretty! I need to make more of these for my girlfriends. =)
