Welcome to Alighieri's Auction House and our esteemed fine jewelry consignment auction. Here, we present an exquisite selection of natural opals, diamonds, emeralds, sapphires, rubies, and other precious gemstones, meticulously set in platinum, gold, and sterling silver. Each piece from luxury brands such as Louis Vuitton and Gucci undergoes a thorough authentication process, including detailed inspections of material quality, craftsmanship, brand-specific traits, and serial numbers to verify authenticity. To ensure the accuracy of our descriptions and the integrity of our representations, all metals have been acid tested, and all gemstones evaluated using a Presidium Gem Tester II, UV Fluorescence, a polariscope, and a trinocular stereoscope at 90x magnification.
