Buyers new to custom jewelry usually ask one question first: “How fast can you make it?” The honest answer is that a clean, well-specified custom ring takes roughly 4–6 weeks from approved CAD to doorstep, and rush orders compress that to 10–14 days only when the stone, the alloy, and the setting style are already decided. This article breaks the schedule down by day so you can see where time actually goes — and where the two most common delays live.

Week 1: CAD design and revision (Days 1–7)

After you send a reference photo or sketch, a CAD modeler builds the ring in Rhino or Matrix. The first render usually lands within 2–3 working days. This stage is where most projects stall. Every revision to finger size, shoulder width, head height, or stone seat restarts the render, and each round-trip can add 2–3 days. We recommend approving a render that includes a top, side, and 45-degree view and a scaled ring-size reference. The GIA 4Cs framework is the right language for specifying the center stone at this stage, because head height and seat diameter depend on the stone's actual measurements, not just its carat weight. We ask every buyer for the stone's measured girdle diameter before we lock the seat.

Week 2: Pattern, casting, and roughing (Days 8–14)

Once the render is approved, the model goes to pattern production — either a 3D-printed wax master or an injected wax pulled from a mold. The wax is invested, burnout, and centrifugally cast in your chosen alloy. Casting itself is a single day, but the flask needs to cool slowly to avoid cracking the casting or the alloy. After casting, the tree is sectioned, sprues are ground off, and each ring is filed to rough dimension. This is the stage where porosity in silver is most often discovered; if pores show up, the piece is re-cast, adding 2–3 days. We photograph the cast tree before cleanup so the buyer can see exactly what came out of the flask.

Week 3: Stone setting and pre-polish (Days 15–21)

Rings move to the setter bench. Prongs are pre-raised, stones are seated, and laser welding is used to close settings without heating the whole shank. For fragile stones like moissanite, the girdle must be protected during this step. After setting, the piece gets a pre-polish to clean up solder marks and tooling scratches before the final finish. This is also where the ring is sized to the target finger, within a half-size tolerance.

Week 4: Final finish, QC, and packing (Days 22–28)

The final polish is either hand polishing or mass finishing depending on the surface required. Then the order moves to our pre-ship QC checklist: fineness mark, prong tightness, symmetry, rhodium thickness (if plated), and weight check against the BOM. Approved pieces are ultrasonic-cleaned, tumbled with anti-tarnish, and packed. Shipping to most US/EU addresses adds 3–7 days by express courier; sea freight for large wholesale orders adds 3–4 weeks and should be planned into the delivery date, not added on at the end.

Where the delays actually happen

Statistically, two delays account for ~70% of late custom orders: (1) CAD revision loops that drag on for weeks, and (2) late stone decisions. If you can lock the render on the second round and send the center stone to the factory before casting begins, you shave a full week. Reorder runs — where a rubber mold already exists — drop to 10–14 days because the CAD and pattern steps disappear. The other hidden delay is alloy: if you ask for a platinum or 18K run, the alloy must be sourced and assayed, which adds 3–5 days we plan for up front.

What is the fastest a custom ring can be made?

A rush production run of a simple solitaire, with stone and size locked, can ship in 10–14 days. Add a premium rush surcharge. Complex pavé or filigree pieces cannot be rushed below 3 weeks without risking QC.

Why does a reorder take half the time of the first order?

The silicone production mold already exists, so CAD, printing, and mold-making are skipped. You go straight to casting, setting, and finishing. That is why we recommend keeping a reorder mold even for one-off-style pieces you may revisit.

Can you start casting before the stone arrives?

Yes, for most settings. We cast and polish the mounting, then set the stone when it arrives — but confirm head height against the stone's real measurements first, or the seat will not fit.

Frequently Asked Questions

What ring sizes can you supply in bulk?

US sizes 5–12 including half sizes. Send a size breakdown with your order and we cast to that curve; comfort-fit inner bands reduce resize requests.

Can I order a mixed size run instead of one size?

Yes. Mixed runs are standard for wholesale: specify quantity per size and we pack and label by size at no extra labor cost.

What is the MOQ for custom ring designs?

50 pieces per design for existing molds; 100–300 pieces when a new mold or CAD model is required.

How should I price rings for retail margin?

Most partners use a 3–4x markup on FOB cost for sterling and 2.5–3x for moissanite solos, which keeps landed cost under 30% of retail.
