RINGS MADE TO ORDER
Round Cut Lab Grown Diamond Engagement Rings
Our round cut engagement rings hold round brilliant lab grown diamonds, the shape with the most sparkle.
A round brilliant has 57 or 58 facets arranged to send light back up through the top of the stone, which is why it shows more sparkle than any other shape. It suits nearly every setting and every hand.
Choosing your round setting
A solitaire shows the cut most clearly and keeps the band slim. A halo frames the center with small diamonds and makes it look wider from above. A hidden halo sets those diamonds under the stone, so the sparkle shows from the side. A three stone ring pairs the round with two side stones for a fuller look.
The Ronora standard
Every stone is a real lab grown diamond, grown with CVD technology and chosen for Excellent cut and VVS-VS clarity, with white diamonds in the D-E-F colorless range. With a round brilliant, cut matters most, because it decides how bright the stone looks. Every gold ring comes with an SGL jewelry certificate and every platinum ring with an ITPL certificate, and every lab grown diamond of 1 carat or more also comes with its own IGI report.
Size and metal
A round diamond faces up a little smaller per carat than an oval or a marquise, because its weight sits evenly instead of along the finger. Our guides show how big a 1 carat diamond looks, and the diamond size chart gives the width in millimeters for each carat. Torn between two shapes? Read oval vs round. Each ring is made to order in our Surat studio. Choose 9K, 14K or 18K solid gold in white, yellow or rose gold. Platinum and 925 sterling silver are also available.
