Everyone jewelry box must have a collar necklace. Whether you are fancy-ing up a plain sweater or accessorizing a little black dress, a chunky necklace is a great go-to piece. Irene Neuwirth is certainly an expert in her craft, her designs have a timeless feel and glamorous esthetic, the lines are clean, the stones are gorgeous and her way in combining textures is amazing. This particular design sets irregular pieces of boulder opals on 18K gold and pave diamond links. Her timeless and elegant designs have been used in red carpets all over, and they’ll set you back over $50,000 which means we have to look for pieces that achieve the same classy look without breaking the bank. I went to BaubleBar and found several designs that would match up to what we are looking for.
