Please note that the facets responsible for creating the enchanting sparkle in gemstones may occasionally result in optical illusions, presenting white or dark/black spots and areas. Therefore, it is essential to carefully select your gemstone/diamond based on millimeter size rather than carat weight to ensure the perfect fit. To assist you in making the right choice, we offer a Size Chart Image for reference or recommend consulting with a local jeweler to accurately measure your setting or gemstone.
