Experience exceptional brilliance with this 1.5 carat round lab-grown diamond, professionally certified by the International Gemological Institute (IGI). Featuring a D color, VS1 clarity, Excellent Cut, Excellent Polish, and Excellent Symmetry, this premium loose diamond delivers outstanding fire, brilliance, and timeless beauty. Whether you're designing a custom engagement ring or upgrading an existing piece, this diamond offers exceptional quality and value.

The round brilliant cut is the world's most popular diamond shape and is renowned for producing the highest level of sparkle. Engineered with precise facet placement, round brilliant diamonds are designed to maximize light return, creating incredible brilliance, fire, and scintillation. If you're searching for maximum sparkle, the round brilliant cut continues to be the benchmark by which all other diamond shapes are measured.

At 1.5 carats, this diamond offers the perfect balance of impressive size and everyday wearability. Its rare D color represents the highest color grade awarded by IGI, producing a bright, colorless appearance that pairs beautifully with white, yellow, or rose gold settings. Combined with VS1 clarity, this diamond appears exceptionally clean to the naked eye, allowing its brilliance to take center stage.

This laboratory-grown diamond was created using the High Pressure High Temperature (HPHT) growth process and is classified as a Type II diamond. The accompanying IGI report also notes the diamond is As Grown, meaning there is no indication of post-growth treatment. This combination of premium growth characteristics and exceptional grading makes it an outstanding choice for buyers seeking a high-quality laboratory-grown diamond.

With Excellent Cut, Excellent Polish, Excellent Symmetry, and no fluorescence, this diamond has all the characteristics that contribute to exceptional light performance. These premium grades work together to maximize sparkle, making this diamond a beautiful centerpiece for a custom engagement ring or other fine jewelry.
