Engagement Rings Manufacturer | AeVa Custom Bridal Jewelry
AeVa is a leading custom jewelry manufacturer in China, trusted by brands that sell engagement rings with consistent, retail-ready quality. We produce made-to-order and batch programs for wedding rings and coordinating wedding bands, and we specialize in building unique engagement rings that remain manufacturable at scale—secure settings, clean symmetry, and repeatable specs from sample to reorder.
Our focus is simple: manufacture the exact product parameters shoppers filter for (shape, setting, metal, stone type) and execute them to a tight quality standard.
Engagement Rings Built to Spec for Brand and Retail Programs
Customers compare quickly: shape, setting, metal, carat, and natural vs lab-grown. AeVa supports that intent with an engineering-first workflow—CAD rules, stone-seat accuracy, and finishing controls that keep each engagement ring consistent across sizes and production runs. For assortments that include wedding rings and wedding bands, we engineer profiles so sets stack as designed.
Engagement Rings Core Specifications Matrix
We can manufacture full bridal sets where wedding rings and wedding bands are developed alongside the engagement ring, not as an afterthought.
These are the parameters shoppers expect to filter—plus the manufacturing controls we apply to deliver them reliably.
| Parameter | Common options | AeVa manufacturing standard |
|---|---|---|
| Center stone type | Natural diamond, lab-grown diamond, moissanite, sapphire, emerald, ruby | Seat geometry and prong/bezel design match stone dimensions and hardness for security. |
| Shape | Round, oval, cushion, princess, emerald cut, pear, marquise, radiant, asscher, heart | Shape drives prong layout and gallery clearance; proportions are tuned to reduce snagging. |
| Setting style | Solitaire, halo, hidden halo, pavé/micro pavé, bezel, channel, three-stone, cathedral, vintage-inspired, toi et moi | Defined tolerances for symmetry, spacing, and stone alignment. |
| Metal | Platinum, yellow gold, white gold, rose gold; two-tone | Alloy and plating specs are standardized per SKU for repeatable color and finish. |
| Karat/purity | 14K gold, 18K gold; platinum options | Karat + wall thickness targets are set to meet durability and market-tier goals. |
| Center size | Carat targets and carat ranges | Mounts are built to real stone measurements for consistent proportions across carat tiers. |
| Diamond framework | 4Cs: cut, color, clarity, carat | Geometry protects cut performance and keeps a clean face-up look. |
| Color grade | D–Z scale support | Assortments can be built around your chosen grade “sweet spot.” |
| Clarity grade | Standard clarity selection (commonly evaluated at 10×) | Intake/QC aligns your clarity promise with face-up appearance standards. |
| Certification | GIA / IGI / other lab reports (as supplied) | Fit is verified against report measurements before final setting. |
| Lab-grown disclosure | “Laboratory-grown / laboratory-created” product-data support | Consistent naming across listings, labels, and SKU feeds. |
| Production model | Ready-to-ship batches or made-to-order | Planning supports launch dates, replenishment cadence, and stable QC. |
| Resizing considerations | Resizable shanks; limits for full eternity styles | Shank thickness and stone placement support resizing where feasible. |
| Returns & resizing | Retail policy varies | Consistent sizing/build notes reduce downstream service friction. |
| Care & inspections | Gentle cleaning + periodic setting checks | Prong integrity and seat finishing are controlled for long-term security. |
Ring Setting Styles We Manufacture
AeVa builds the setting families customers search for, with strict symmetry and security standards:
- Solitaire engagement ring: clean, center-forward. We control prong thickness, tip finishing, and alignment so the stone sits straight and secure.
- Halo engagement ring and hidden halo: added sparkle and presence. We hold concentricity and spacing so halos read crisp, not wavy.
- Three stone engagement ring: balanced coverage. Side-stone heights are matched for a smooth face-up line.
- Bezel set engagement ring: smooth edges for active lifestyles and glove-friendly wear. Bezel lip thickness is controlled to protect the stone without overpowering it.
- Pavé engagement ring / micro pavé: micro-setting precision with magnified alignment checks.
- Cathedral setting engagement ring: elevated center with supportive shoulders and head stability.
For unique engagement rings, we produce east-west layouts, toi et moi designs, split shanks, twisted bands, and vintage/art-deco influences (milgrain, engraving, filigree-inspired elements) while enforcing minimum thickness rules for durability.
Stone Programs and the 4Cs
AeVa supports modern buying preferences without changing the quality bar:
Diamond engagement ring programs (natural) Built for classic bridal positioning. When you supply grading reports, we manufacture to those measurements and verify fit before final setting.
Lab grown diamond engagement ring programs Manufactured with the same tolerances as natural-diamond mounts. We also support consistent “lab-grown / lab-created” product naming across SKUs.
Moissanite and colored gemstones Moissanite engagement ring programs deliver high brilliance at accessible tiers. Sapphire engagement ring options and emerald engagement ring options offer distinctive color and storytelling.
How we design around the 4Cs We build mounts that present stones well: cut-friendly galleries, color-complementary metal options, clean face-up finishing, and proportional head/band sizing across carat tiers.
Engagement Rings Metals, Karat, and Finishing Standards
We manufacture bridal rings in platinum and gold to defined finishing standards:
- Platinum engagement ring builds for premium weight and durability targets
- 14K gold engagement ring builds for a strong balance of durability and value
- 18K gold engagement ring builds for richer color and premium positioning
- Yellow, white, and rose gold options, plus two-tone
Finishing controls include consistent mirror polish, comfortable inner shank rounding, crisp edges where required, and even plating for white gold. On pavé, bead size and uniformity are standardized for a clean sparkle field.
Manufacturing Process and QC Standards at AeVa
Our factory workflow is designed for repeatable quality across sizes and reorder cycles—critical for engagement jewelry, wedding rings, and wedding bands.
- DFM-first CAD rules Minimum thickness and seat/prong standards by setting type, plus tolerance planning so halo spacing and pavé rows stay consistent.
- Precision production + setting Casting/CNC workflows selected per design complexity; prong, pavé, and bezel setting executed to checklists with symmetry checks.
- QC + documentation Magnified inspection for pavé alignment and prong integrity, comfort checks, and fit checks so wedding rings and wedding bands sit as designed. Settings can be built to supplied GIA/IGI reports with standardized SKU spec sheets.
Resizing considerations: we engineer resizable shanks where feasible and flag full-eternity styles that are commonly limited for resizing—helping your after-sales workflow stay predictable.
