brilliance, timeless shape, and balanced proportions. A 1 carat round cut stone offers strong presence
on the finger while maintaining classic elegance suitable for all styles.
Does a 1 carat round diamond sparkle more than other shapes like oval or princess? +
Yes. Round cut diamonds are engineered for maximum light performance with optimal brilliance, fire, and
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? +
Round diamonds sometimes appear slightly smaller than elongated shapes like oval or pear because they
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
Excellent cut, Excellent polish, and Excellent symmetry (3EX) when possible.
This ensures optimal sparkle and light performance at the 1 carat size.
Which color and clarity grades look best in a 1 carat round cut lab grown diamond? +
Round cuts hide inclusions well and maintain brightness even at slightly lower clarity grades. Popular

exceptional sparkle at 1 carat.
Are 1 carat round cut lab grown diamonds certified by IGI or GIA? +
Yes. Most 1 carat round lab grown diamonds come certified by IGI or GIA. The report includes the 4Cs,
growth method (CVD or HPHT), and precise proportions that influence brilliance.
Is a 1 carat round diamond durable for daily wear, especially in rings? +
Yes. Round diamonds are one of the most durable shapes because they have no sharp edges or pointed
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,
bezel settings, and three-stone rings. Their symmetrical shape makes them the most versatile
diamond cut for jewellery design.
Does a 1 carat round cut lab grown diamond offer good value compared to mined diamonds? +

or cut grade at the same budget. A 1 carat round lab grown diamond provides premium brilliance at a
more accessible price point than mined options.
Do 1 carat round cut lab grown diamonds come in different proportions and brilliance levels? +
Yes. Round diamonds vary in cut quality, table percentage, depth, crown angle, and pavilion angle.
