Why choose a custom oval cut diamond engagement ring?
Created in the late 1950s by Lazare Kaplan, the oval cut diamond delivers brilliant light reflection while offering a visually larger surface area per carat compared to round brilliants. Its smooth curved shape resists chipping and creates an elegant, elongated profile on the finger.
Our master goldsmiths in Surat hand-select oval diamonds with ideal length-to-width ratios (typically 1.35 to 1.50) to minimize bow-tie shadow effects while maximizing fire. Whether set with a delicate hidden halo, a classic solitaire band, or a 3-stone trilogy layout, your oval ring is custom-engineered to your exact style preferences.
All Riolls custom oval diamond rings are crafted in solid 14k, 18k gold or platinum and delivered worldwide with independent gemological certification and lifetime care.
Everything you need to know about custom oval diamond rings
What is the ideal length-to-width ratio for an oval cut diamond?
The classic elongated ratio for an oval diamond is between 1.35 and 1.50. A ratio of 1.35–1.40 yields a slightly fuller oval shape, while 1.45–1.50 produces a slender, finger-elongating profile. At Riolls, our gemologists inspect every stone to ensure balanced proportions without an overpowering bow-tie shadow.
What is the bow-tie effect in oval cut diamonds?
A bow-tie effect is a dark shadow shaped like a bow-tie across the central facets of fancy cut stones (oval, pear, marquise). While almost all oval diamonds exhibit a slight bow-tie due to facet geometry, expert cutting minimizes its appearance. Our gemologists inspect all oval stones in 360-degree high definition to select stones with minimal bow-tie contrast.
Why do oval diamonds appear larger than round diamonds of the same carat weight?
Oval diamonds have an elongated surface area with shallow pavilion proportions compared to round brilliant cuts. This spread means a 1.50-carat oval diamond covers noticeably more surface area on the finger than a 1.50-carat round diamond, giving superior visual value for your investment.
What are the best setting styles for a custom oval diamond ring?
Solitaires with hidden halos, 4-claw compass prongs (north-south-east-west), and ultra-thin pave bands are the most sought-after settings for oval cut diamonds. A hidden halo adds subtle sparkle beneath the stone while keeping the oval silhouette front and center.
