Your GIA Cert Upload Just Failed. Your Auction Opens in 72 Hours.
If you're running estate jewellery auctions, you know certificate lag kills liquidity before the first bid.
Jewelry auctions are not generic auctions. Every lot carries a gemological story: origin, treatment, certificate, and a provenance chain that buyers interrogate before they bid. Our Gems & Jewels desk at Social Animal builds auction platforms purpose-designed for jewellery houses, estate auctioneers, and trade-only jewellery marketplaces. Timed, live, and simulcast bidding modes with GIA, IGI, GCAL, SSEF, and Gübelin certificate integration, 360-degree video galleries under multiple light sources, parametric search by stone attribute, and KYC/AML compliant buyer verification. The platform treats each lot as a certified object, not a commodity -- because that is how real jewellery bidders evaluate and how auction liquidity is built.
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%.
What is holding your current website back?
Common gaps we find in nearly every audit.
How We Build This Right
Every safeguard, built in from Day 1.
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.
What We Build
Purpose-built features for your industry.
Assign the Gems & Jewels desk -- a team that works exclusively with jewellery, gemstone, and auction clients, never pivoting to furniture marketplaces between projects
Use a pattern library from prior auction builds -- solved problems, tested components, real bidder behavior data -- so you're not paying us to figure out how jewellery auctions work
Configure buyer's premium tiers, seller commission structures, sliding-scale overrides, and per-lot exceptions without touching code
Stop spending Tuesday mornings manually matching spreadsheets to bank transfers because invoices generate automatically on hammer and payments reconcile against each lot
Display USD, EUR, GBP, CHF, and HKD with live FX rates so bidders see their home currency while your house reports in reference currency
Remove the friction of mental currency arithmetic at the moment a Zurich buyer needs to decide whether to go one more increment on a London sale
Enable pre-auction maximum bids, auto-increments per lot, and tie-break handling so absentee buyers are treated as first-class participants
Build trust with absentee bidders by showing them full transparency on why they won or lost: what the next bid was, where their maximum sat, what the tie-break outcome was
Generate catalogue PDFs with automated lot numbering, condition report compilation, and subscriber distribution -- replacing the InDesign-and-email workflow
Replace the three-day InDesign workflow that still burns two people's time with a 20-minute automated process that matches your house's brand exactly
Publish permanent post-sale results pages for every sold lot, creating linkable references that compound SEO authority over time
Turn the catalogue you ran two years ago into an SEO asset that's still generating organic traffic and building authority today
Built on a Modern, Secure Stack
Our Development Process
From discovery to launch. Quality at every step.
Auction House Operations Audit
Week 1-2We 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.
Platform Architecture Design
Week 2-4Then 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.
Build: Catalogue, Bidding Engine, KYC
Week 4-12Next.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.
Catalogue Migration and Dry-Run Auction
Week 12-14We 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.
First Live Sale and Optimisation
Week 14+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.
