Description from the seller
This highly exclusive pendant features a round-shaped opal. Crafted with exceptional skill, the opal is widely admired for its dynamic color play that changes with every movement. The stone's remarkable transparency is immediately noticeable. It is set in a handcrafted 18k gold-plated silver setting, discreetly engraved with our logo as a testament to its craftsmanship. A matching 18k gold-plated chain is included, allowing the pendant to be worn immediately.
At Heart of Gemstone, we distinguish ourselves by offering only flawless gemstones. This piece has been meticulously inspected to ensure it is completely free of imperfections before being presented in the auctions.
What further sets us apart is the addition of an ALGT certificate, provided by an internationally renowned laboratory headquartered in Antwerp. ALGT is globally recognized for its advanced technology and highly accurate analyses. The included certificate not only enhances the value of the item but also provides you with the assurance that you are receiving an authentic and high-quality piece, independently tested and verified by experienced gemologists.
