A double-strand chain of solid 18k gold and nearly 600 carats of polished golden rutilated quartz & prasiolite (green amethyst). In the center of the necklace is a cluster of large golden rutilated quartz & prasiolite briolettes (ranging from a 20 carat polished prasiolite to a faceted rutilated quartz weighing 273.75 carats!) all hung from an antique victorian 10k gold snake belt buckle with faceted diamond eyes.
