This 14k Gold-filled/Vermeil Green Chalcedony Triangle Necklace is striking! It can be ordered in any length up to 21". You can wear it up near your collar bone and layer it with another necklace, or you can wear it in a standard 16, 17" or 18" length. The 14k gold-filled chain comes with a spring clasp. Please specify in checkout comments what length you prefer. If you don't have a preference, I will send a 17" length.
