Unusual Starburst pin/pendant by silver master, Antonio Pineda. The center of the medallion and circular stones are black onyx. The rays of the sun are obsidian. The center medallion is 2 3/4 inches in diameter. The necklace is on a 30 inch chain by Tane. The chain does not have a defined closure but one of the necklace links is slightly open so that the pendant can be removed and worn separately as a brooch.
