What to check before you say yes
Do not approve a custom ring from one attractive render. Approve a named revision only after the exact stone or placeholder, ring size and metal, dimensioned views, daily-wear and wedding-band tradeoffs, intended setting construction, and seller terms are clear.
A CAD can show intended geometry. It cannot prove the finished ring's polish, stone seating, prong contact, comfort, tolerances, or workmanship. Open the latest render and quote side by side, complete the five-gate record below, and choose approve, revise, request missing evidence, or pause.

A render is evidence, but only of what it actually shows
The words CAD, model, and render often get used as if they mean the same thing. They do not always refer to the same deliverable. A CAD model is digital geometry. A render is an image produced from that model. The customer may never receive the manufacturing file.
A written specification identifies the revision, materials, stone, measurements, finish, price, and terms. A wax or resin model, when offered, adds physical evidence about scale and general profile. The finished ring is where polish, stone seating, prong contact, surface finish, tolerances, and workmanship can be inspected.
GIA's Quality Assurance Benchmarks cover physical matters such as ring sizing, assembly, finishing, alloys, and settings. That supports an important boundary: a digital model can document what is planned, but it cannot prove that the manufactured ring meets physical workmanship benchmarks.
Model or render
- Useful for
- Planned shape, proportions, viewable clearances, detail placement, and dimensioned geometry.
- Cannot establish by itself
- Final polish, actual stone seating, prong contact, comfort, or workmanship.
Written specification
- Useful for
- Exact revision, stone identity, metal, ring size, finish, dimensions, price, timing, and policies.
- Cannot establish by itself
- Whether the finished object was made correctly.
Wax or resin model
- Useful for
- General scale, profile, and sometimes the wedding-band relationship.
- Cannot establish by itself
- Final metal behavior, stone setting, finish, or exact wearing comfort.
Finished-ring inspection
- Useful for
- Checking the delivered piece against the approved record and identifying visible workmanship concerns.
- Cannot recover
- Terms and expectations that were never documented before production.
The Render-to-Ring Approval Record
This five-gate record is a Driona editorial framework built from three evidence classes: what is visibly modeled, what is agreed in writing, and what can only be checked on the physical ring. It is not an engineering certification or a guarantee.
Approve
The named revision and written terms are complete enough for you to authorize production.
Revise
The evidence is present, but a specific design detail needs to change.
Request evidence
You cannot evaluate the design because a view, measurement, identity detail, or term is absent.
Pause
A conflict or unresolved risk makes production premature.
Confirm the exact version, stone, size, and material
Start by identifying the object you are being asked to approve. “The latest version” is not precise enough if several images and messages exist.
Record the revision name or number and date, ring size, metal and purity, finish and color, center-stone shape and actual length × width × depth when known, exact-stone or placeholder status, grading-report identity where applicable, and every detail that must survive later revisions.
If the center stone has a laboratory report, match the model and written specification to the fields that report actually provides. IGI explains that its laboratory-grown diamond reports can include the description, shape and cutting style, measurements, and grading results. Report formats vary by issuer, service, and date. GIA, for example, changed its D-to-Z laboratory-grown diamond service in October 2025, so do not assume every current document uses older terminology.
A report identifies and describes the stone within the scope of that service. It does not prove the mounting's workmanship, seller performance, or whether the stone looks the way you expect in the setting. Driona's separate guide explains how to verify the grading report and exact stone.
When a placeholder is acceptable
A placeholder can be useful early in design, but it must be labelled. If the final stone is not selected, approval should remain conditional on updating the model or written specification with the actual stone measurements and confirming any affected proportions.
“Oval, 2 carats” is not the same as the exact length, width, and depth of a particular oval stone. Two stones with the same shape and carat label can occupy the setting differently.
If the design direction itself is unsettled, step back and turn the idea into a clear ring brief. If an old ring or family stone is involved, first decide whether the heirloom should be changed and confirm custody, insurance, removal risk, and material handling in writing.
Request views with measurements, not only glamour angles
An enlarged top view can make a ring look clear and impressive while hiding height, underside construction, and scale. Ask for the information, not a particular software format.
- Top view. Check overall outline, center-stone orientation, side-stone layout, halo or pavé placement, and band taper.
- Side view. Check profile height, basket or bezel projection, gallery or bridge, prong direction, and setting-to-shank relationship.
- Through-finger or underside view. Check the interior opening, supports, hidden halo, under-gallery, and details that may affect cleaning, fit, or resizing.
- Three-quarter view. Check how the top, side, and setting details meet as one form.
Measurements worth recording
The exact list depends on the design, but a useful approval set normally identifies:
- Center-stone length, width, and depth when the exact stone is known.
- Overall setting or profile height.
- Band width and thickness at meaningful points, including any taper.
- Halo, hidden-halo, shoulder, or side-stone layout.
- Bridge or gallery clearance relevant to a wedding band.
- Engraving location and extent.
- ring size and interior shape used in the model.
Test daily wear and the wedding-band relationship
The top view does not answer how high the ring sits, where another band meets it, or how the combined set may feel. Use the side and through-finger views to discuss the wearing goal.
Decide whether you want a straight band that sits flush, a straight band with a deliberate gap, a curved or contoured band, an open band, a custom-matched band, or no wedding band beside the ring.
GIA's ring-sizing guidance notes that ring width, interior form, openings, and the combined width of a bridal set can affect sizing and fit. A digital view can reveal geometry, but it cannot guarantee comfort. Physical sizing and an exact paired model are more informative when available.
Use Driona's CLEAR Stack Test to decide whether the desired result is straight, curved, open, custom, flush, or intentionally gapped. Then put that outcome into the approval record. “Wedding band compatible” is too vague without naming the band and intended relationship.
A higher profile can create clearance for a straight band, but it may stand farther from the finger. A low profile can feel compact while limiting a flush stack. Pavé, hidden halos, engraving, open galleries, and very fine details can affect cleaning, future work, and resizing. These are tradeoffs to document, not automatic defects.
Review the setting plan without pretending the render proves workmanship
A CAD can show the planned number and position of prongs, a bezel outline, gallery supports, vulnerable-corner treatment, pavé layout, and the relationship between the setting and shank. Review those features carefully.
It still cannot prove the final stone is seated correctly or that the metal makes proper contact. GIA's setting guidance explains that security depends on physical factors such as bearing fit, prong contact, dimensions, support, material, and workmanship. The detailed benchmarks apply to the examples and materials they describe. They are not universal consumer specifications for every ring.
Questions for a prong setting
- How many prongs are planned, and where will they contact the stone?
- Are pointed or vulnerable corners protected appropriately for the chosen shape?
- What supports connect the head or basket to the shank?
- Does the side view show the intended bearing and prong direction clearly enough to discuss?
- Which parts will be checked after casting, assembly, stone setting, and finishing?
For a bezel, halo, pavé, or side-stone design, ask how the edge, support, stone layout, and future service have been planned. GIA's Quality Assurance Benchmarks and stone-setting bench guidance are useful reminders that the physical result matters, not just the digital outline.
If setting terms are unclear, compare engagement-ring setting types before requesting a revision. The goal is not to become the setter. It is to make sure the intended construction and later physical inspection are not being confused.
Lock the price, policies, timing, and final approval in writing
The final approval should identify the named revision and the commercial terms attached to it. Screenshots scattered across messages are harder to audit than one written summary.
Record the final price and included materials, exact stone or placeholder status, metal, ring size, dimensions, finish, engraving, production and delivery range, revision terms, post-approval changes, resizing, warranty, cancellation, returns, mismatch or fault remedy, remake process, shipping, insurance, duties, and custody where relevant.

Record one decision
How to request a revision clearly
Use four parts. The customer does not need to dictate a manufacturing solution. Describe what looks wrong, identify where it appears, and state the wearing or design outcome that must be preserved.
Weak: “Can you make it less bulky?”
Clearer: “In the side view of revision C, please reduce the visual mass of the basket while preserving the documented straight-band clearance. Show the revised profile height and bridge relationship before I approve it.”
Another example: “In the top view, the halo outline extends beyond the center stone more than I expected. Please show a version with the halo brought closer to the stone and provide the updated overall width.”
When to pause instead of approving
Pause when the exact revision is unclear, the model uses an unexplained placeholder, the ring size or metal is absent, the side or underside view is missing, or important dimensions are not tied to the latest revision.
Also pause when the desired wedding-band relationship conflicts with the profile, a hidden detail differs across the render and quote, written policies are missing, or a customer-owned stone or old metal has no clear custody and material-handling plan.
Check the finished ring against the approved record
Keep the named revision, written specification, stone report, and terms until the ring arrives. At handover, confirm the stone identity, metal description, finish, engraving, ring size, proportions, visible details, and intended wedding-band relationship.
Look for obvious looseness, snagging, roughness, sharp edges, unfinished areas, or a material mismatch with the approved record. This is a concise acceptance check, not a substitute for professional inspection. If something appears loose, damaged, sharp, or materially different, stop wearing it and contact the seller.
Use the checklist with Driona's custom-design process
As verified on August 23, 2026, Driona's public custom page describes a firm quote and a 3D render from every angle, free revisions until approval, and payment after approval. It currently shows a 24–48 hour quote/render stage, 10–14 days of crafting after approval, and typical delivery in two to three weeks.
The page also says custom pieces sit outside the standard 30-day return window and describes what happens if a piece arrives faulty or not as approved. Those are current public statements, not permanent terms. Reconfirm the exact terms for your order.
Common CAD approval questions
Is a CAD exactly what the finished ring will look like?
No. A CAD or render can document intended geometry and visible details. It cannot prove final polish, color under every light, exact comfort, stone seating, prong contact, tolerances, or workmanship. Use the physical ring to inspect the physical result.
What measurements should appear on a ring CAD?
Ask for the measurements needed to understand this design: actual center-stone dimensions or clear placeholder status, ring size, setting/profile height, band width and thickness at meaningful points, and any clearance or detail measurement that affects fit, stacking, engraving, or appearance. There is no universal list of safe numbers for every ring.
What if the exact center stone has not been chosen?
Treat the model as conditional. Record that it uses a placeholder, then update the model or written specification with the final stone's actual measurements and confirm any affected proportions before production.
Can a CAD prove the prongs will be secure?
No. It can show the intended prong count, position, support, and proportions. Finished security depends on the actual material, bearing fit, contact, stone setting, finishing, and inspection.
Should I ask for a wax or resin model?
Ask when physical scale, profile, or stack fit remains hard to judge and the seller offers one. A prototype adds evidence, but it still is not the finished metal, set stone, or final surface.
How do I know whether a wedding band will sit flush?
Review the engagement ring and exact band together from the side and through-finger views. Check the basket or bezel projection, bridge or gallery clearance, band width and contour, and whether the intended result is truly flush or includes a deliberate gap.
What happens after I approve the CAD?
The seller's written terms should explain when production begins, what changes are still possible, how timing is estimated, when payment is due, and how mismatch, fault, resize, return, repair, or remake requests are handled. Do not assume one jeweler's process applies to another.
