Natural Big Blue Topaz 14.8ct 14.8mm VVS Round Cut

This remarkable blue topaz presents an extraordinary face: 14.8ct in a round brilliant cut at nearly 15mm diameter, with a vivid, deeply saturated sky blue that fills the large crown with colour and life. The stone's exceptional VVS clarity allows light to travel freely through the entire body, producing brilliant, scintillating reflections across the broad faceted surface. The colour is a clean, vibrant Swiss-sky blue with superb uniformity and a luxurious depth that is immediately striking.

Blue topaz of this size and clarity is produced through irradiation and heat treatment of natural colourless topaz from Brazil, a permanent process that develops the stone's signature vivid blue. At nearly 15ct and 14.8mm, this is a collector-grade centerpiece stone suited to bespoke cocktail rings, grand statement pendants, and custom jewellery creations where an impressive, high-clarity blue gemstone is the focal point. Blue topaz is the traditional November birthstone and a perennial favourite in fine jewellery design.
