Making the Cut Our stones are carefully cut and polished by skilled craftsmen to ensure that they meet our procurement standards and shine a different kind of brilliance. Quality Control We carefully check each stone to make sure it meets Blocaci's high standards of cut, clarity, carat and color. If anything takes away from the beauty of the stone, we won’t accept it. Refined Designs We map the unique design for each stone, prioritizing beauty above all else to ensure all Blocaci jewelry are of the highest quality (and that our engagement rings have that mesmerizing sparkle). 5A Cubic Zirconia We use gem-quality AAAAA Cubic Zirconia Simulated Diamonds in our jewelry. Cubic Zirconia, or CZ, is a stone so optically close to Diamond that most jewelers cannot tell the difference between a CZ and a Diamond with the naked eye. It resembles the same optical characteristics, radiance and beauty as Diamonds. CZ is much less expensive than Diamond, optically flawless, and can be created in a variety of different colors. The biggest difference is that CZ is 70% heavier than Diamond. CZ is extremely durable with a hardness rating of 8.5 compared to 10 for Diamond.
