This is a pretty pendant set with AAA-grade Golden Imperial Topaz haloed by natural white zircon and mounted in solid sterling silver with yellow gold vermeil. The small pendant measures 0.58 of an inch in length and 0.26 of an inch in width. It is suspended from a 20-inch 925 silver chain also plated in 18K vermeil. Yellow gold vermeil is a premium jewelry finish that only uses genuine gold and precious sterling silver. The coating of vermeil prevents tarnishing, increases the metal-life, and offers a superior finish. The oval-cut yellow topaz measures 4mm x 3mm, while the sparkly white zircons (not to be confused with lab-created cubic zirconium) range in size from 0.9mm to 1.5mm round gemstones. Both chain and pendant are stamped 925 and the pendant is signed.
