Native cart
Custom prices. Native checkout.
Every ring your shopper designs has a price no catalog product could predict — this stone, this metal, this size. Gemtheon handles it the Shopify-native way: the app maintains a dynamic product, and Shopify Functions apply the exact configured price to the cart line. Shoppers check out through your normal Shopify checkout — same payment methods, same taxes, same trust.
- Exact configured price on every cart line — no "price on request"
- Full spec travels with the line item: stone certificate, metal, size, engraving
- Discounts, taxes, and payment gateways work unchanged

Order sync
Every order synced. Every stone verified.
Orders land in your Shopify admin like any other order — and sync to your Gemtheon dashboard with the full configuration, ready for CAD handoff and production. And because those up to 1 million diamonds live in someone else's vault, Gemtheon confirms a stone is still available the moment it's added to the cart, so you never sell a diamond twice.
- Orders appear in Shopify admin and the Gemtheon dashboard — no double entry
- Stone availability checked at add-to-cart, automatically
- Configuration, certificate, and engraving attached to every order
Shopify questions
Straight answers for Shopify merchants.
No. Gemtheon ships as a theme app block for Online Store 2.0 themes — you add it in the theme editor the same way you add any section, and remove it just as cleanly. No liquid edits, no leftover code if you uninstall.
The app maintains a dynamic product behind the scenes, and Shopify Functions apply the exact configured price to the cart line. It's the platform-native mechanism — not a draft-order workaround — so discounts, taxes, and every payment method you already offer keep working.
Never. All inventory and pricing requests route through Shopify's App Proxy, verified with HMAC signatures, and your key stays on the server. Nothing sensitive ships in your theme or in the browser.
In your Shopify admin, as normal orders — with the full ring configuration attached as line item properties. The same order syncs to your Gemtheon dashboard with the stone certificate and CAD-ready specs, so production starts without retyping anything.
