Buying Guide
What should you look for when choosing a 1 carat lab grown diamond? Consider color, clarity, cut, certification, and ethical origin. IGI and GIE certifications provide independent grading and origin assurance. Color grades range from near colorless to colorless; higher color ranges typically appear brighter in sunlight and white gold or platinum settings. Clarity grades indicate how many inclusions are visible; VVS to VS are commonly preferred for jewelry that highlights stone purity. The cut quality affects brilliance, fire, and scintillation, so prioritize well-rated faceting for best sparkle.
Size versus perceived brilliance matters. Larger stones in the 1.5 CT range deliver a stronger impression but may require more precise settings. For those prioritizing sustainability and ethics, verify the lab origin and energy use credentials. Some stones include extra certificates like “Brilliant Grown” to bolster trust in authenticity.
Setting compatibility is essential. Round brilliant cuts pair well with classic prong settings, while Asscher cuts suit bezel or halo designs. When selecting a diamond for a custom piece, request a scale image to confirm actual carat dimensions and table width. If color is paramount, opt for D-E colors and a VS or VVS clarity to maximize brilliance with minimal visible inclusions.
