CAD Approval
Once you clear your design deposit, our CAD artists construct high-density digital renderings modeling your ring down to the exact millimeter. Review your structural design from multiple angles, adjusting proportions until it flawlessly aligns with your expectations.

Production
Following final CAD sign-off, your ring enters physical production in our historic Los Angeles jewelry facility. Our master setters execute casting, precise stone assembly, and rigorous hand-polishing over a detailed 2 to 4-week timeline before final quality control clearance.
Choosing Your Custom Engagement Ring Foundation
| Setting Architecture | Visual Profile & Anatomy | Optimal Stone Shapes | Design Advantage |
|---|---|---|---|
| Classic Solitaire | Single focal stone held securely by minimal, high-polished metal claws or prongs. | Round Brilliant, Oval, Cushion, Emerald Cut | Directs absolute focus to your center diamond while maintaining classic heirloom aesthetics. |
| Dainty Halo | A delicate border of micro-pavé diamonds completely encircling the main center stone. | Cushion, Round, Pear, Radiant | Significantly enhances perceived center stone dimensions while providing excellent outer edge protection. |
| Three-Stone (Trilogy) | A prominent center gem flanked harmoniously by two complementary side accent diamonds. | Emerald Center with Cadillac/Trapezoid sides; Round with Pears | Creates incredible visual span across the finger; traditionally symbolic of a couple's past, present, and future. |
| Antique & Detailed Accented | Intricate vintage elements including structural milgrain milgraining, filigree, or hidden galleries. | Asscher, Marquise, Old European Cuts | Delivers a completely custom, artistic appearance that feels like an authentic heirloom from day one. |
A Modern Legacy Built on Integrity
"An engagement ring is not merely a combination of metal and diamond—it is an elegant piece of visual storytelling. By handling the manufacturing directly under our roof in Los Angeles, we bypass classic retail markups while ensuring every prong, edge, and basket transition passes rigorous, professional oversight before it ever reaches your box."
Our Interactive 3D Renderings
Our goal is to give you the best possible idea of what your finished ring will look like prior to the arrival, which is why we include an interactive 3D rendering to help you visualize the finished piece. Once we finalize you CAD, we can generate an interactive 3D rendering and send it to you for your review.
You'll be able to use the interactive viewer on the right to inspect the 3D model. You can rotate, zoom, and view the design from every angle before giving your final approval.

Custom Engagement Ring FAQ
How long does the custom engagement ring process take from start to finish?
Our standard production lifecycle spans approximately 2 to 4 weeks from initial quote acceptance to final insured courier delivery. This timeline accommodates the detailed rendering of your initial 3D digital CAD model, your personalized review edits, structural casting, hand-setting, and final independent gemological quality control assessment.
Can I source custom lab-grown fancy colored diamonds through your diamond shoppers?
Absolutely. We specialize in sourcing rare, high-quality fancy colored lab-grown diamonds, including premium yellow, romantic pink, deep blue, and vibrant green options. Our expert diamond shoppers work in tandem with our design network to isolate ideal color saturation levels and crystal purities that pair seamlessly with your custom mounting layout.
What is a custom 3D CAD model, and can I make adjustments to it?
CAD stands for Computer-Aided Design. Before any metal is cast in our workshop, our designers construct a millimeter-accurate digital model of your custom ring. This stage allows you to preview the exact physical balance, prong placements, and profile heights of your ring. We welcome and integrate your modifications during this phase until the file accurately matches your vision.
Can I utilize my own family heirloom diamonds or existing gemstones?
Yes, we frequently design custom ring settings specifically tailored to reset client-owned ancestral stones or upgrade existing mountings. We recommend connecting directly with our Los Angeles team at 213-627-1300 to share the exact carat metrics and geometric dimensions of your stones so our artists can build safe structural frameworks around them.
Does my custom ring order come with structural protections or a sizing warranty?
Every original jewelry design manufactured by our firm includes a dedicated lifetime craftsmanship warranty protecting your piece against unexpected manufacturing defects. Additionally, to ensure absolute comfort on the hand, most custom engagement ring orders include a complimentary professional resizing adjustment within the first 30 days of client receipt.
