When a custom order runs late, the instinct is to assume the bench is behind schedule — that casting, setting, or polishing is taking longer than quoted. In practice, that’s rarely where the time actually goes. Once a design is CAD-approved and the stone and metal specs are locked, in-house production of a finished piece typically moves in 4-6 business days. The delays that blow up delivery windows almost always happen before that clock starts: slow CAD sign-off from the retailer’s own customer, incomplete stone specs at order entry, mid-build change requests, and unresolved metal or finish details. All four of those sit substantially on the retailer’s side of the process — which means most of the fix is also on the retailer’s side, not something to chase the manufacturer over.
This isn’t a defense of manufacturers who miss dates. It’s a map of where the days actually go, so retailers can close the gaps they control instead of pushing on the one stage that’s usually already moving fast.
Where the Time Actually Goes
Every custom order has two owners: the retailer, who manages the relationship with the end customer and defines the piece, and the manufacturer, who executes the build once the design and specs are final. Delays get misattributed constantly because the retailer only sees “the order is late” — not which side of the handoff is holding it.
| Delay Point | Primarily Controlled By | What Actually Causes It |
|---|---|---|
| CAD approval turnaround | Retailer | Render sent to the end customer, no internal follow-up SLA, revision rounds |
| Stone spec completeness at order entry | Retailer | Shape/size/color/clarity not fully defined, especially on antique or fancy-shape stones |
| Melee QC baseline for accent stones | Retailer | “Match the center stone” given as a spec instead of a color/clarity baseline |
| Mid-build change requests | Retailer | Customer changes their mind after CAD is already locked and approved |
| Metal karat, finish, and plating | Retailer | “White gold” or “yellow gold” given without karat, finish, or plating detail |
| Casting, setting, and polishing | Manufacturer | Bench queue and finishing sequence once specs are locked |
| Sourcing a stone outside standard stock | Manufacturer, triggered by retailer-side ambiguity | Unusual size/shape combination not caught until after CAD |
The first four rows are where most “why is my order late” conversations should actually start. The last two are where they usually do start — and where there’s typically the least slack to find.
The Four Delay Sources That Aren’t the Manufacturer’s Fault
Slow CAD Approval Turnaround
This is the single biggest lever in the entire timeline. Once a CAD render goes out, production is effectively paused until someone signs off on it — and that sign-off usually has to travel through the retailer to their own customer before it comes back. A render sitting in an inbox for four days costs four days, no matter how fast the bench downstream is running. Manufacturers get blamed for a delay that occurred entirely before the build slot was even opened.
The fix isn’t complicated: set an internal SLA for how long a CAD sits before someone follows up with the customer. Don’t let a build slot go idle waiting on a decision that was never in the manufacturer’s hands to begin with. See how the CAD-to-production handoff works if you’re mapping this into your own intake process.
Incomplete or Ambiguous Stone Specs at Order Time
Round brilliant is a commodity cut with tightly standardized proportions, so “round, 1.00ct, VS1, G” is close to unambiguous on its own. That’s not true across the rest of the catalog. Antique and premium-tier cuts — Old Mine, Old European, Hexagonal, Moval, Lozenge, Kite, Trillion, Criss-Cut, Padparadscha — and the regular fancy-shape tier — Emerald, Asscher, Cushion, Oval, Pear, Marquise, Radiant, Princess, Heart — don’t share a single universal proportion standard the way round brilliant does. A “cushion” spec that doesn’t nail down length-to-width ratio or crown height can bounce back and forth for days before cutting or setting ever begins, because the manufacturer is guessing at what the retailer’s customer actually pictured.
Two more spec gaps show up constantly:
- Melee accents. If the design calls for pavé or accent melee, the order needs a stated color/clarity QC baseline up front. Melee moves as uncertified parcel goods checked against that baseline — it isn’t individually or parcel certified — so “match the center stone” isn’t a usable spec, it’s a guess that has to get resolved before the setting stage.
- Certification lab. For any center stone 0.30ct and up that needs to ship with paperwork, decide IGI or GIA at order entry. Both are available, but deciding after CAD is already done adds a sourcing loop that didn’t need to exist.
The fix is a locked stone-spec field before CAD submission, not before casting. Browse certified diamonds or the exotic and antique shape range to confirm exact proportions before the spec goes in, rather than after.
Mid-Build Change Requests
Once CAD is approved, a change to ring size, stone count, or shape forces a partial or full restart. This isn’t the manufacturer being rigid — a cast piece already has that design’s geometry set into the metal. Reworking it after the fact isn’t a quick fix, it’s a new build wearing the old order number.
The fix is treating CAD approval as the actual spec lock, and communicating that to the end customer before they sign off, not after. If a change request is going to happen, it needs to happen before approval, where it costs nothing.
Metal and Finish Ambiguity
“White gold” by itself doesn’t specify karat (14K vs. 18K), finish (high polish, brushed, hammered), or plating cycle (rhodium refresh). Vague metal calls generate a clarifying-question round trip before the bench can even start — a preventable delay that has nothing to do with production speed.
The fix is standardizing the intake form so karat, finish, and plating are required fields, not a follow-up email sent two days after the order was supposedly placed.
What’s Actually the Manufacturer’s Responsibility
Once CAD is locked and specs are complete, in-house cutting, setting, and polishing is the fast, predictable part of the process — this is where the 4-6 business day turnaround applies, measured from CAD approval to finished piece. That window does not apply to loose diamond selection or delivery; those are separate steps with their own timeline, and conflating the two is one of the more common ways expectations get set wrong at the quoting stage.
The one piece of manufacturer-side time that’s genuinely variable is sourcing a stone outside standard stock — an unusual size or shape combination that wasn’t caught until after CAD. That’s a real variable, but it’s a known, quotable one once the spec is locked, not an open-ended delay.
Keeping stone sourcing, cutting, setting, and polishing under one roof also removes a category of delay entirely: the handoffs between a separate stone vendor and a separate finishing bench, where an order sits in transit or in someone else’s queue with no visibility. One vendor, one shipment, one relationship means there’s one place to look when something is running behind — not three, with the retailer stuck coordinating between them.
How to Close the Retailer-Side Gaps
Most of the fix here isn’t a process overhaul — it’s a checklist applied consistently at intake, before the order ever reaches CAD:
- Set a CAD-approval SLA with your own customer. Give them a turnaround window (48 hours is reasonable) and follow up when it lapses instead of waiting indefinitely.
- Lock stone specs before CAD submission, not after. Exact shape, size, color, clarity, and cert lab if applicable — and know which tier the shape falls into, since antique and fancy cuts need more explicit proportions than round brilliant does.
- State a melee QC baseline whenever the setting includes pavé or accent stones, rather than referencing the center stone.
- Lock metal karat, finish, and plating on the same order, not as a separate follow-up.
- Treat CAD approval as the change-request cutoff. Anything requested after approval is a new build, not a revision.
- Confirm ring size and any other fit details at intake, not at final QC.
Any retailer working through a wholesale trade account can build these fields directly into their own intake form once, and stop re-litigating them order by order. If you’re setting this up and want it reviewed against how orders actually flow through CAD and production, that’s a five-minute conversation via contact — faster to fix at the template level than to keep chasing individual orders after they’ve already slipped.
Frequently Asked Questions
What’s the average turnaround for a custom jewelry order?
Once CAD is approved and stone and metal specs are locked, in-house production of a finished custom piece typically runs 4-6 business days. That window starts at CAD approval, not at order submission, because the steps before approval — design review and spec confirmation — sit on the retailer’s side of the timeline and vary order to order.
Why does CAD approval take so long?
CAD approval depends on the retailer getting sign-off from their own end customer, not on the manufacturer’s production capacity. A render can sit unreviewed for days while the bench downstream is idle and ready to go. Setting an internal follow-up SLA on pending CADs closes most of this gap without needing any change on the manufacturing side.
Can I request a change after CAD is approved?
Yes, but it resets part of the build rather than adjusting it. A cast piece already has that design’s geometry set into the metal, so a shape, size, or stone-count change after approval is closer to a new build than a revision. Treating CAD approval as the real spec lock — and communicating that to the end customer before they sign off — prevents this from happening mid-build.
Is melee held to the same certification standard as center stones?
No. Melee moves as uncertified parcel goods checked against a stated color and clarity baseline, not individually graded stones. Loose diamonds 0.30ct and up carry individual IGI or GIA certification. If a custom piece pairs a certified center stone with melee accents, only the center stone carries paperwork — the melee needs its QC baseline specified separately at order entry.
Does the 4-6 day turnaround apply to loose diamond orders too?
No. That window applies only to finished custom jewelry, measured from CAD approval to completed piece. Loose diamond selection and delivery is a separate step with its own timeline and isn’t part of that window — quoting it as if it were is one of the more common ways delivery expectations get set incorrectly upfront.
What information should be locked in before submitting a custom order?
Stone shape, size, color, clarity, and certification lab (IGI or GIA) if applicable; a melee QC baseline if the setting includes accent stones; metal karat, finish, and plating; and ring size or other fit details. Locking these fields before the order goes to CAD — rather than resolving them through follow-up emails afterward — removes the majority of avoidable delay before production even starts.
