We Recreated a Brilliant Earth Engagement Ring: Detailed CAD to Photoreal Render

The client didn't want an interpretation or “inspired by.” They had a specific reference — an oval-cut, three-stone ring from Brilliant Earth with a rope-twisted diamond band and a decorative gallery — and they wanted a faithful recreation so they could commission it on their own terms: their metal, natural or lab-grown diamonds, and their exact finger size.

It's one of the most common custom requests we get. Someone finds the perfect design but wants it in a different metal, with a lab-grown center stone, in their size, or at a price that works for them. A precise CAD recreation is what makes that possible — you keep the design you love and make every other choice your own.

We rebuilt the ring from the ground up in CAD (Rhino and MatrixGold), matching the reference detail for detail. This is the step that separates a true recreation from a rough lookalike — and where meticulous modeling earns its keep.

• The rope-twisted shank, fully micro-pavé set with matched stone sizes and spacing
• The openwork decorative gallery beneath the head — the scrollwork most shops simplify away
• Pear-shaped side diamonds, each in its own basket, set at the correct angle
• The oval center in a six-prong head, proportioned exactly to the reference
• Every element modeled to real casting tolerances, so it casts and sets correctly the first time

With the model confirmed for accuracy, we rendered it photorealistically — true yellow gold, real diamond fire in every facet, from every angle. The client could see the finished ring, exactly as it would look in metal, before committing to production.

Because the renders are physically accurate to the CAD model, what's approved on screen is precisely what gets cast — no surprises when the ring arrives.

“Exact” is easy to promise and hard to deliver. The character of a ring like this lives in the parts that are tempting to skip: the precise twist of the band, the scrollwork in the gallery, the size and spacing of each pavé stone, the shape of the prongs, and the exact angle the pear side stones sit at.

We model those details rather than approximate them — because a faithful recreation is only faithful if it holds up from every angle, in the metal, in real life.

Recreating a design you love isn't about settling for a copy — it's about control. You keep the exact look and make every other decision yours:

• Your metal — yellow, white or rose gold, or platinum
• Natural or lab-grown center stone, at the carat and quality you choose
• Your exact finger size, modeled in from the start
• Small, tasteful tweaks — proportions, band width, a hidden accent or engraving
• A budget that works, without giving up the design

Bring us anything: a screenshot, a photo, or a link to a ring you love — from Brilliant Earth or anywhere else. We handle the whole process end to end: detailed CAD modeling, photorealistic rendering for your approval, and manufacturing-ready files (STL · 3DM · STP · OBJ) that your jeweler or casting house can produce.

Whether it's a faithful recreation like this one or an original design of your own, it's one studio and one process — from the first reference to cast-ready files, with you approving every step.

Found the one — but want it in your metal, your stone, your size, or simply at the right price? Send us the link or a photo, and we'll recreate it in precise 3D CAD and photoreal renders, then hand you production-ready files. Tell us about your piece and get a quote.
