A 16x12mm rectangular cushion peanut obsidian with 0.43 carats of round smoky quartz in 18K yellow gold over sterling silver earrings - the peanut obsidian earring where smoky quartz accents complement the stone's warm, dark character. Peanut obsidian's natural volcanic glass with distinctive lighter spotting creates a stone with individual character; smoky quartz's warm transparent brown creates a tonally harmonious accent.
