Rare Peanut Obsidian Sterling Silver Necklace

This unique Peanut Obsidian necklace has warm reddish-brown circular formations against a dark grey-black base, set in sterling silver. The stone has several well-defined spherulites, giving the piece a stronger contrast and more desirable pattern than material with faint or irregular markings - includes a hypoallergenic stainless steel chain with a jewellery pouch. Measurements - 3.3cm x 2.7cm x 0.6cm with 42cm chain. Peanut Obsidian is an uncommon lapidary material from Mexico and is prized for these distinctive rounded formations. Good-quality pieces with clear, evenly developed reddish-orange spherulites are harder to find, which is why well-patterned material is generally more sought after by collectors and jewellery makers. A Closer Look Despite its trade name, Peanut Obsidian is more accurately described as a spherulitic volcanic glass or perlitic material. Its rounded “peanut” patterns are mineral spherulites that formed during cooling and later alteration, with iron oxides contributing to their reddish-brown colour.
