This is a sapphire necklace by HERNÁN HERDEZ. I purchased it at Shinzone. The sales certificate is included. It's a necklace with a strong presence, and it looked great paired with casual styles like a T-shirt. It's in beautiful condition, having been worn only twice, but please refrain from purchasing if you are very particular.
