This beautiful necklace is made with a temperature sensitive color changing glass "stone" and several layers of Sterling Silver wire. The necklace has been made at 18" on a Sterling Silver chain, but length can be adjusted to fit your personal taste (just leave me a note upon purchase). The pendant hangs 1.75" from chain. Finished with a lobster clasp. Included with the necklace is a mood color chart card, printed on water resistant paper. The necklace will arrive carefully packaged in a charming box, perfect for easy gifting! All my jewelry is handmade and made with patience, care and love.
