RendaRing — Jewellery Costing Tool | Upload 3DM for Live Metal Prices & Stone Sourcing
Upload your 3DM. Get instant jewellery costing, live bullion prices, diamond and gemstone options — all from your CAD file. RendaRing is the complete jewellery costing tool for trade jewellers. Upload any .3dm file and the platform calculates live gold, platinum and silver costs from the bullion fix, suggests diamonds and coloured stones that match your model from 763,000+ certified inventory, and renders every material — all in one place.
From CAD File to Fully Costed Quote in Minutes
Costing jewellery from a CAD model is needlessly slow. You design in Rhino or MatrixGold, then manually weigh up gold costs against a bullion price you found online, phone around for diamond prices, and piece together a quote from three or four different sources. It takes hours. Sometimes days.
RendaRing collapses that entire jewellery costing process into a single upload. Drop in your .3dm file and the platform does the rest — calculating live metal costs directly from the bullion fix using your model’s geometry as an automatic gold weight calculator, suggesting diamonds and coloured stones that match your design, and rendering every material on request with photo-realistic accuracy. One platform. One quote. Minutes, not days.
Whether you have your own in-house CAD designer or work with freelancers, RendaRing turns any .3dm file into a fully costed, beautifully rendered, client-ready presentation. No waiting for renders. No manual pricing. No separate stone searches.
One Upload. Fully Costed.
Live Jewellery Costing
RendaRing reads your .3dm geometry, calculates the metal weight automatically, and applies the live bullion fix. Switch between 9ct, 14ct, 18ct gold, platinum, palladium, and silver — costs update in real time. No spreadsheets. No guesswork.
Diamond & Stone Suggestions
RendaRing reads your model and suggests stones that match from 763,000+ certified diamonds and coloured gemstones. Compare, price, and select directly alongside your design. One platform, complete quotes.
Instant Material Rendering
See your piece rendered in any metal instantly. Switch materials in the interactive 3D viewer, then generate photo-realistic images and videos on demand in seconds — ready for client presentations or your website.
Stop Manually Costing Jewellery
Every manual step in your jewellery costing process is time lost, margin leaked, and a customer who might walk away. RendaRing automates the entire cost calculation directly from your CAD model.
Manual jewellery costing takes hours — weighing models, checking bullion sites, calling stone suppliers. Upload a 3DM file to RendaRing and get a fully costed breakdown in seconds.
Metal costs are calculated from the live bullion fix, not yesterday’s rate or a manually updated spreadsheet. Your jewellery costing reflects the real gold price, protecting your margins on every quote.
Stop phoning around for stone prices. RendaRing reads your model and suggests matching stones from natural, lab-grown, and coloured diamonds plus gemstones — right next to your design.
Who Is RendaRing For?
Retailers with In-House CAD
If you have a CAD designer on staff producing .3dm files in Rhino or MatrixGold, RendaRing gives them instant rendering, live costing, and stone sourcing without additional software licenses or render farms. Your designer focuses on design. The platform handles everything else.

More Than a Render. A Complete Sales Tool.
The interactive 3D viewer is not a static image. It is a fully navigable, real-time visualisation of your jewellery piece. Rotate it, zoom into the setting detail, switch metals and see the material update live. Show your customer exactly what their piece will look like from every angle, on any device.
When you need assets for a client presentation, social media post, or website listing, generate photo-realistic images and videos on demand directly from the viewer. No waiting for a render queue. No exporting to third-party software. Click, generate, download — in seconds.
Want to let your customers explore the piece themselves? The interactive 3D viewer is available as an add-on for client-facing use. Embed it directly on your website or share a link with your customer so they can rotate, zoom, and inspect the piece on any device — before they even step into the shop. It is the most powerful selling tool in bespoke jewellery, and it starts with a single upload to RendaRing.
Stones That Match Your Model
RendaRing reads your 3DM file, identifies the stone specifications, and suggests matching diamonds and gemstones automatically. It connects directly to our live stone APIs, giving you real-time access to one of the largest inventories available to independent jewellers. Over 763,000 certified diamonds — natural and lab-grown — alongside a comprehensive coloured gemstone catalogue covering sapphires, rubies, emeralds, tanzanites, aquamarines, and more.
Search and filter by shape, carat weight, colour, clarity, cut grade, certification, and price. Check live availability. Build a complete specification alongside your CAD design and present a fully costed proposal to your customer in minutes, not days.
Every diamond over a certain weight comes with full certification details and competitive trade pricing. Whether your customer wants a natural round brilliant, a lab-grown oval, or a Padparadscha sapphire, you can find it, price it, and include it in the quote without picking up the phone.
