GEM CAPTURE · GLOBAL DIGITAL INFRASTRUCTURE
The digital standard for fine gemstones.
Capture, catalogs, and trade infrastructure for the global gem trade. Try the samples below. Mike Ching builds the capture and catalog layer the gem trade still runs without: daylight-balanced turntable video, stills, and 360° that load fast on mobile, plus optional live inventory pages. Born in Sri Lanka, trained in European gemmology, years building digital systems in Australia. All of it poured into the one thing that never left: gems. Whether stock sits in Colombo, Prague, or New York, buyers see honest colour, documented provenance, and export-ready assets.
Captures
Trade capture examples. Tap any stone for video, stills, and 360°. Note: Most gemstones are available to purchase. Real examples from studio and field work. Ruby, sapphires, spinels, garnets, and more. Same workflow on every stone: honest colour, turntable video, stills, and 360°. Open any tile to see the standard. Note: Most gemstones are available to purchase.

Two hubs
From pit to buyer, without the friction
The trade does not stop at the border. We run capture and catalog infrastructure from Sri Lanka and Prague so exporters, mining partners, and international houses can show stock properly, document provenance, and close deals without shipping every stone to every inquiry.
Studio locations and shipping-
Hub 01
Sri Lanka studio
Location
Colombo, Sri LankaServing
Colombo, Beruwala, Ratnapura, and the gem beltFocus
Exporters, sourcing agents, and dealers at the sourceStones are captured at the table or in studio before they clear customs. Turntable video, stills, and 360° replace weak phone clips. Export-ready media and traceability records sit with the physical stone from pit to desk.
-
Hub 02
Prague studio
Location
Unetice, Prague, Czech RepublicServing
Central Europe and international trade networksFocus
EU dealers, jewelry houses, and trade-show prepHigh-value lots arrive fully insured for capture, vaulting, and handoff. European buyers get the same daylight-standard media and catalog ingest as Sri Lanka stock, without guessing from a grainy WhatsApp forward.

Pricing
How digital and capture pricing works
No public rate card. Every dealer inventory is different. This is how we scope and quote before work starts.
-
01
Scope first
Stone count, species, deliverables (video, 360°, catalog), and any custom tool needs. We agree what success looks like before a session is booked.
-
02
Quote before work starts
Session fee per stone or lot, catalog build phases, and tool development scoped separately. Written quote, no verbal guesswork.
-
03
Pass-through costs separate
Hosting, domains, third-party certs, rush processing, and shipping quoted upfront where they apply.
-
04
You approve every phase
Media delivery, then catalog launch, then optional automation. No surprise invoices mid-project.
-
05
Support quoted separately
Team training, inventory updates, and feature additions agreed in writing after the initial build.
