Kimai
Four international storefronts, conversion, SEO, promotion and landing-page work since 2019.
Jewelry eCommerce development

What we do
A website design that reflects your brand
We specialize in designing and developing bespoke shopping experiences and unique features for jewelry brands. We primarily work with Shopify and Shopify Plus, but can also assist with any other eCommerce platform.
Bespoke PDPs
Product pages purpose-built for jewelry. For CAST: size pills for rings, length selection for necklaces, browsing by material, and stock checks and error handling in the size logic. For Kimai: gold color swatches. For Héloïse & Abélard: variant selection with preview images and a "Try in store" button. We also integrate pay-in-installments widgets such as Klarna and Alma.
Advanced search & filters
Filters by category, style, stone, material, color, price, size and length for CAST. Algolia search for Kimai, plus generated pages for yellow, rose and white gold.
Engagement ring configurator
Built for Kimai: customers choose the ring, diamond and shape from a toolbar on the product page.
Custom engraving
Front and back engraving for Kimai, with character limits built into the engraving flow.
Commerce
Selling across markets, online and in store
Checkout, marketing and booking features built for the jewelry brands we work with.
Multi-market storefronts
Four international websites for Kimai, with separate currencies for the US, UK and Europe and a French translation.
Duties & taxes at checkout
Duties and taxes calculated at checkout through DHL for Raemi, so international customers prepay before delivery.
Appointment booking
Private appointment and consultation booking for Kimai, connected to HubSpot, and for Héloïse & Abélard, connected to Pipedrive.
Gift with purchase
A bespoke gift-with-purchase feature for CAST, triggered by cart value or promotional conditions and configurable in the Shopify theme editor. When no gift is offered, it doubles as an in-cart promotional banner.
Referral, rewards and reviews
A refer-a-friend promotion for Cyber Monday and a customer reward system for Kimai, plus product reviews through Stamped.

FAQ
Common questions
What does a jewelry site need that other eCommerce sites don't?
High-quality imagery that still loads fast, variant structures that handle metal, stone and size without becoming unmanageable, and often an appointment or made-to-order flow alongside the standard checkout. Configurators and engraving come later. Most brands start by getting the product pages right.
Do you build engagement ring configurators?
Yes. We built Kimai's, where customers choose a diamond, a setting, a shape and a size, and the price updates as they go. It runs on Shopify Plus with a React front end. A configurator is the most involved thing a jewelry storefront asks for, and it needs the catalog structured around it from the start rather than bolted on later.
We sell in several countries. How does that work on Shopify?
Two approaches, depending on what you need. Shopify Markets handles catalog prices per market, which is what we used for Héloïse & Abélard's US launch. For separate storefronts per market, Kimai runs four international websites from one codebase, with different currencies for the US, UK and Europe and a French translation. The second is more work and gives you more control.
Our customers get charged customs on delivery. Can that be fixed?
Yes. We integrated DHL into Raemi's Shopify checkout to calculate and collect duties and taxes at the point of sale, based on the products ordered and where the customer is. They see the full cost before they pay.
