Thank you for viewing. The infinity ∞ engraving is likely the brand name. I believe I purchased it in Hawaii. At first glance, they appear to be the same color, but perhaps due to their natural origin, one appears to be pink-purple, and the other appears to be more pink-orange. They have a beautiful luster and shine. The 14k∞ engraving is in the middle of the main bar. The clasp is in the shape of a round flower, with the ∞ engraving, and the rest is unknown. The total weight is approximately 1.28g. Please consider it if you are interested ♥ To prevent any issues, price negotiations are not possible. Thank you for viewing.
