IGI Certified Round Brilliant Solitaire Diamond Engagement Ring | Classic 6-Prong Peg Head Setting | Lab-Grown Diamond | Gold, Silver & Platinum | Handcrafted by Excellent Jewels
Timeless. Unshakeable. Eternally hers.
There is a reason the round solitaire has been chosen more than any other ring in the history of engagement jewelry. Not because it is simple — but because it is perfect. Because when something is designed without flaw, nothing needs to be added. No halos. No side stones. No distractions. Just a diamond, held up to the world, and the light it gives back.
The IGI Certified Round Brilliant 6-Prong Solitaire Engagement Ring by Excellent Jewels is that ring — refined to its purest, most powerful form. A brilliant round center stone cradled in six precisely placed prongs, elevated on a clean, consistent band, and built to be worn every single day for the rest of a lifetime.
Six prongs, not four. Because some things are worth holding more carefully.
This is not just a ring. This is a declaration with nothing to hide and everything to say.
Why Six Prongs?
Four prongs expose more of the diamond — more face, more light, more visual openness. Six prongs do something different. They hold the stone with a security that feels almost ceremonial — each prong a quiet promise, evenly spaced, structurally sound, protecting the diamond from every angle. And visually, six prongs echo the classic Tiffany silhouette — the most recognized, most revered solitaire profile in the world.
More protection. More presence. More forever.
Why the Round Brilliant?
With 57 to 58 precision-cut facets engineered specifically for maximum light return, the round brilliant is the most scientifically optimized diamond shape ever created. It does not merely reflect light — it multiplies it. Scintillation from above. Fire from the side. Brilliance from every angle, in every room, under every light.
It is not the most popular diamond shape by coincidence. It is the most popular because nothing else comes close.

Identical chemical, physical, and optical properties to mined diamonds. The same brilliance. The same hardness. The same forever — chosen with conscience.
The Peg Head Setting — Precision That Scales
The peg-style head is the engineering backbone of this ring. Precision-crafted as a separate component and set onto the band, it allows the shank to maintain a consistent, elegant 2.0mm–2.2mm width at every carat size — while the head itself scales in height and thickness to safely and beautifully secure larger diamonds.
The result: a ring that always looks perfectly proportioned, whether it carries a 0.50 ct stone or a statement 3.00 ct center. The band never overwhelms. The diamond always leads.
Six prongs rise from the head like a crown — reaching just far enough over the girdle to hold the stone with absolute security, while leaving the pavilion open and the table fully exposed to light.
