Diamond Details
At Blue earth Diamond, we ensure beauty, value, and authenticity by carefully selecting only high-quality diamonds. We use diamonds in the D–E–F colour range for excellent brightness and a clean white look. Our diamonds are graded VVS1, VVS2, and VS1, making them nearly flawless to the naked eye. Each diamond is IGI or GIA certified, with all details clearly listed for full transparency and confidence.
Colour
Diamond colour refers to a diamond's natural hue, graded from D to Z, with D being the most colourless and rare. D–E–F diamonds are colourless and offer the best brilliance and clarity. At Blue earth Diamond, we use only D, E, and F colour diamonds for superior shine and elegance. Lower grades show warmer or noticeable colour, while fancy yellow diamonds are valued for their rich yellow tone. All colour grades are certified by IGI or GIA for authenticity.
Clarity
Diamond clarity refers to natural inclusions formed as a diamond develops deep within the earth. These tiny features help gemologists assess a diamond's quality and are graded under 10× magnification. Common clarity grades include VVS1, VVS2, VS1, and others. VVS and VS diamonds have inclusions that are not visible to the naked eye, offering excellent clarity and brilliance. At Blue earth Diamond, we use only VVS1, VVS2, and VS1 diamonds to ensure beauty, value, and satisfaction. All clarity details are certified by IGI or GIA for full transparency.
Carats
Diamond carat measures a diamond's weight, affecting its size and appearance. Different shapes of the same carat have varying millimetre dimensions, shown in our chart. We offer a range of carat sizes to suit your style and budget. Carat choice depends on jewelry balance, design, and personal preference. Custom options are also available to tailor the carat and specifications to your needs.
