scintillation. At 1 carat, a well-cut round diamond will typically outshine most other shapes due to
precise, symmetrical faceting.
Does a 1 carat round cut diamond look bigger or smaller than other shapes at the same weight? +

carry more weight in depth. However, their superior brilliance and perfect symmetry create a bright,
full visual impact that balances the difference.
What cut quality is ideal for a 1 carat round lab grown diamond? +
Cut is the most important factor for round diamonds. For the best brilliance, choose

growth method (CVD or HPHT), and precise proportions that influence brilliance.

corners. In a secure prong or bezel setting, they are ideal for everyday wear in engagement rings,
pendants, and earrings.
Which settings look best with a 1 carat round cut lab grown diamond? +
Round diamonds shine in all settings, including solitaires, halos, pavé bands, vintage designs,

diamond cut for jewellery design.
