Why choose a custom round cut diamond engagement ring?
The round cut diamond has remained the premier choice for engagement rings for over a century. Developed by Marcel Tolkowsky in 1919, the 58-facet round brilliant cut is engineered to reflect light back through the top table of the stone with unmatched scintillation and fire.
When you commission a custom round diamond ring at Riolls Jewels, you are not limited to standardized off-the-shelf settings. We craft bespoke 4-prong solitaires, cathedral settings, hidden halos, vintage milgrain borders, and pave diamond bands around your exact GIA-certified round stone.
Handcrafted in solid 14k, 18k, 22k gold or 950 platinum by master goldsmiths in Surat, your custom round diamond ring arrives with full hallmarking, gemological certification, and direct workshop value.
Everything you need to know about custom round diamond rings
Why is the round brilliant cut the most popular diamond shape?
The round brilliant cut diamond features 57 or 58 mathematically calculated facets designed specifically to maximize light reflection, fire, and brilliance. It reflects more than 90% of light entering the diamond back to the eye. Its symmetrical round shape is timeless, versatile across any setting style (solitaire, halo, three-stone), and maintains the highest resale value of all diamond shapes.
Why is GIA Cut Grade so critical for a round diamond?
Unlike fancy shape diamonds (like oval or emerald) which do not receive an official GIA cut grade, round diamonds receive a dedicated GIA Cut Grade from Excellent to Poor. A GIA "Excellent Cut" ensures ideal depth, table percentage, and crown/pavilion angles, directly dictating how intensely your diamond sparkles.
Is a 4-prong or 6-prong setting better for a custom round diamond ring?
A 4-prong setting highlights more of the diamond surface and creates a squarer silhouette, allowing maximum light entry. A 6-prong setting offers enhanced stone security and accentuates the round symmetry, giving a classic vintage appearance. Our master goldsmiths craft both styles in solid gold and platinum.
How long does a custom round cut diamond ring take to craft?
A custom round diamond ring at Riolls takes 6 to 10 weeks from initial design approval to completion. This includes GIA stone selection, custom 3D CAD modeling, hand-forging in raw gold or platinum, hand-setting, and hallmarking.
