New for 2020. An art deco 1.25CT cushion cut main stone with a halo of princess cut and marquise diamonds. Classic and stunning brilliance.For the first time in history, Swarovski has applied ideal diamond-cut standards to zirconia. Swarovski’s Pure Brilliance Cut makes Swarovski Zirconia one of the finest diamond simulant on the market. The Pure Brilliance Cut offers the same brightness as a Tolkowsky ideal cut, recognized as the world’s most perfect diamond cut. Every Swarovski Zirconia is marked with a microscopic 'SWAROVSKI ZIRCONIA' laser engraving to ensure Swarovski authenticity. The laser engraving is invisible to the naked eye and does not impair the brilliance of the stone.
