Certification

At Star Diamond NYC, we pride ourselves on offering diamonds and fine jewellery of the highest quality. To ensure that every diamond and piece of jewellery meets global standards, we partner with the International Gemological Institute (IGI), one of the most trusted and recognized certification lab in the world.

Cut Grade: An assessment of how well the diamond has been cut, including proportions, polish, and symmetry.

Shape & Measurements: The exact shape and dimensions of the diamond.
