What Jewellery Auction Platforms Actually Handle — And Why Generic Bidding Software Fails
Your lot goes live with a GIA certificate number, a clarity grade, and three static photos. A dealer in Antwerp opens your catalogue page, scans for the treatment disclosure — doesn't find it in the first six seconds — and closes the tab. That's how jewellery auctions break on generic platforms. The data payload for a certified stone isn't optional decoration: origin documentation for colored stones, treatment status aligned to CIBJO and AGTA standards, grading attributes from GIA, IGI, or GCAL, provenance chains for estate pieces, and 360-degree video under multiple light sources. Trade buyers filter on these attributes the way property investors filter by postcode and yield. Bury that data in a paragraph and your liquidity dies. Our Gems & Jewels desk has built auction platforms for estate houses, trade-only marketplaces, and hybrid retail operations across the UK, US, and Hong Kong. Same technical core, calibrated differently depending on who's actually bidding. Show your buyer the certificate number in the search interface or watch your sold-through rate drop 30%.
项目失败的原因
Running jewellery auctions on a generic HiBid or Proxibid template is honestly one of the most common mistakes we see Those platforms weren't built to surface certificate data, so grading attributes end up buried somewhere in a description paragraph -- if they're mentioned at all. Trade bidders don't dig through prose to find a clarity grade. They walk. And the numbers back this up: sold-through rates on certified stones drop 20-30% on generic platforms compared to platforms where proper attribute search actually works.
No 360° video is a real problem Still photos can't communicate how a stone behaves under different lights, and for alexandrite, parti-sapphire, and many fancy-colour diamonds, a single static image actively misleads buyers. They either pass entirely or bid low to hedge against what they can't see. But give them a proper 360° gallery captured under multiple light sources? Average hammer price on colour-shift stones doubles. That's not a marginal improvement -- that's the difference between a successful sale and a room full of passed lots.
Certificate verification shouldn't be a PDF download Nobody wants to open a file, squint at a report number, then go manually look it up on the GIA website mid-auction. In jewellery auctions, trust is the transaction -- and a buyer who can't verify a certificate in the actual moment of bidding doesn't bid high. Or they don't bid at all. Verification needs to be one click, one page, done. That's the standard we build to.
Generic KYC with no sanctions screening is a problem the moment your international buyers start registering Jewellery lots cross regulatory thresholds faster than most categories -- a single fancy-colour diamond parcel can clear $500K easily. Inadequate KYC is a compliance risk in UK, EU, and US jurisdictions. But here's the real kicker: clunky verification also costs you legitimate buyers who abandon registration when it takes 20 minutes and three uploaded documents just to place a bid.
Trade and retail running on separate systems -- or worse, blended into one undifferentiated experience -- damages both audiences Trade wants dealer-only lots, wholesale pricing, and bulk tools. Retail wants a polished public catalogue with clear buyer's premiums. Blend them together and neither group gets what they need. Split them across systems and you're maintaining two codebases forever. Role-gated access on a single platform is the correct architecture. It's how we build it every time.

Certificate Integration (6 Labs)
We integrate GIA, IGI, GCAL, SSEF, AGL, and Gübelin reports out of the box. Every grading attribute -- carat, colour, clarity, cut, fluorescence, origin, treatment -- is stored as structured data, not buried in a text field. QR-bound verification is attached to each lot. One-click lookup goes directly against the issuing lab's database. Buyers get the answer before doubt has a chance to form.
360° Video Lot Galleries
V360, Diamond360, and custom turntable video integrate as the primary lot asset -- not a secondary tab, not an afterthought. Multiple light-source captures for colour-shifting stones are standard. Everything lazy-loads with CDN fallback so the experience doesn't collapse when 800 bidders hit the same lot page simultaneously at the start of a timed auction.
Timed + Live + Simulcast Bidding
One platform, three modes. Timed for scheduled lots where bidders work at their own pace. Live webcast with an auctioneer calling the room. Simulcast for in-room plus online running concurrently -- identical to how Christie's and Phillips handle their flagship sales. Real-time bidding is built on Supabase Realtime, and we've proven it at 10,000+ concurrent bidders without the platform flinching.
KYC + AML + Sanctions Screening
Mandatory ID verification, address verification, AML screening, per-lot bidding limits, trade-tier credit references -- all of it. Thresholds configure per jurisdiction: UK, EU, US, Hong Kong, Switzerland. The compliance workflow isn't bolted on at the end. It's designed into registration from day one, because retrofitting KYC into a live auction platform is a genuinely miserable experience we've saved multiple clients from.
Trade and Retail Tier Gating
Dealers get dealer-only lots, trade pricing, bulk bidding tools, and memo arrangements. Retail buyers get the public catalogue and standard buyer's premium. Same platform underneath -- role-based access separates the experience entirely. Nobody sees what they shouldn't, and nobody misses what they need. It's a cleaner architecture than running parallel systems, and it's dramatically cheaper to maintain.
Provenance and Estate Chain Display
Estate lots carry prior-owner history, exhibition records, publication references, and condition reports. All of it's structured as ProvenanceRecord schema -- which means Google indexes it properly and AI search surfaces it accurately. So a lot that appeared in a 1987 Sotheby's Geneva catalogue doesn't just get a footnote in a description. It becomes a discoverable, linkable reference page that builds authority for your house over time.

我们的流程
01
Auction House Operations Audit
We start by reviewing your catalogue preparation workflow, bidding registration process, payment reconciliation, and compliance requirements for every jurisdiction you operate in. No assumptions. We've seen enough variation between a London estate house and a Hong Kong trade platform to know that the details matter before a single line of code gets written.
Week 1-2
02
Platform Architecture Design
Then we define the data model for your certified lots, select the bidding mode configuration that fits your sale calendar, map the certificate verification integration, choose the KYC provider, and design the payment flow. Blueprint stage. Everything documented, nothing ambiguous.
Week 2-4
03
Build: Catalogue, Bidding Engine, KYC
Next.js frontend, Supabase Realtime for live bidding, certificate integration, KYC flow, Stripe plus bank-transfer payment routes. Continuous Vercel Preview URLs throughout -- so your team sees exactly what's being built at every stage, not a reveal at the end of a six-week sprint.
Week 4-12

Catalogue Migration and Dry-Run Auction
We migrate past sales to establish provenance history in the new system. Then a full dry-run auction with real bidders on test lots -- not internal QA, actual people bidding. Live-bidding UX gets tuned based on what they actually do, not what we assumed they'd do in a planning document.
Week 12-14

First Live Sale and Optimisation
Go-live is monitored, not just deployed. First auction runs with us watching the real-time metrics. Post-sale we review the analytics together -- bid patterns, drop-off points, conversion on timed versus live lots. Ongoing retainer covers sale-cycle support, catalogue ingestion, and the small optimisations that compound into significantly better performance over 12 months.

常见问题
珠宝拍卖平台与通用拍卖平台有什么区别？
三个方面将珠宝拍卖平台与通用平台区分开来：宝石披露、证书整合和来源显示。通用平台将每件拍品视为标题、描述和照片。但珠宝拍品需要结构化字段来记录克拉重、颜色、净度、切割、产地、处理、评级实验室和证书编号——因为这正是买家筛选和竞价的依据。如果没有这些字段，您会将贸易买家流失到能够正确展示数据的平台。这不是偏好问题。这是流动性流向的地方。
您如何处理 GIA、IGI 和其他评级证书？
每件拍品直接链接到发证实验室的报告，带有二维码绑定验证。评级属性作为结构化数据存储，显示在筛选器和拍品详情页面中，可以通过一次点击与实验室自己的数据库进行验证。我们开箱即支持 GIA、IGI、GCAL、SSEF、AGL 和 Gübelin。任何自定义评估都可以作为 PDF 附加，并进行结构化属性提取——这样即使没有实验室证书的宝石也不会被视为二等拍品。
您支持定时、现场直播和模拟竞价一起进行吗？
支持。一个平台，三种模式——定时拍卖适用于按计划流动的库存，现场直播适用于有拍卖师的重点拍卖，模拟竞价将现场竞价与在线实时竞价相结合。这个模拟竞价模式与 Christie's 和 Phillips 运行旗舰拍卖的方式相同。它基于 Supabase Realtime，并能够大规模运行。
您如何处理买家验证和高价值珠宝的 KYC/AML？
注册需要强制性 KYC：文件验证（护照或国民身份证）、地址验证、针对制裁名单的 AML 审查，以及内置于合规工作流程中的每件拍品竞价限额。贸易买家需要经过两层流程——业务验证加信用参考。所有这些对于在英国、欧盟、美国、香港和瑞士监管阈值以上运营的珠宝拍卖都是必需的。我们按司法管辖区配置阈值，而不是一刀切。
该平台能同时处理贸易和零售买家吗？
可以，通过受限访问——而且这种限制确实有效。零售买家可以看到带有标准买方佣金的公开目录。贸易买家可以看到仅限经销商的拍品、贸易价格、批量竞价工具和备忘录安排。底层是同一个平台，基于角色的访问控制着每个层级看到的内容。无需维护单独的系统，也没有既不为任何一个受众服务的混合体验。
