Dual Universe: A Prestige Theme Migration and Custom Features for a Swiss Luxury Jewelry Store

We moved a Swiss luxury jewelry store from a legacy Shopify theme to a Shopify 2.0 theme (Prestige), then added the custom features that the standard theme does not include. The most distinctive one is a “dual universe” welcome that sends visitors to the half of the store that fits them.

Project brief

The brand sells two different kinds of jewelry: everyday pieces and engagement pieces. The store ran on a legacy theme, so most pages could not be rearranged without custom code. The owner wanted to design the pages themselves, with drag-and-drop sections on every template, and to add features that premium fashion stores usually have.

Most of the page design and building was carried out by the store owner. Our part was to set up the 2.0 theme, build the custom features, and support the team with theme know-how while they worked.

Goals

• Self-managed design Give the owner a 2.0 theme where they can build and change pages with sections.
• Modular product pages Product pages made of sections and blocks, with freedom over their structure.
• Premium store features Add the functions the standard theme lacks, built so the team can maintain them.
• Shopify know-how Explain how each feature works so the team can use it without us.

The dual universe welcome

The two product ranges speak to different shoppers, so we gave each one its own entrance. A pop-up on the home page asks which universe the visitor is shopping, everyday jewelry or engagement jewelry. Each choice leads to its own landing page built from collections, and the navigation switches to match the selection. The image above is a simplified diagram of this flow, not a screenshot of the store.

Custom features

Alongside the welcome, we added a set of features to the new theme:

• Upsells and cross-sells inside the product page, in a custom block driven by product metafields so the team can choose them for each product
• Images in the mega menu navigation
• Visual category navigation on collection pages, using a collection metafield for the subcollections
• Collapsible information rows moved into the product info column, instead of below the pictures
• A wishlist, and collection layouts that can hold images and videos to guide shoppers
• Estimated delivery dates on the product page, static or set through metafields
• A slider of trust and reassurance icons in the product info section

How we worked

Phase 1: theme setup and customizations

We chose and set up the 2.0 theme, then built the features above. Each customization came with a short video showing how to set it up with the store’s own data.

Phase 2: support with theme design

While the team built their pages, we answered questions and shared guidance and how-to videos, on demand. We also noted one thing early: custom code does not carry over when a theme is updated, so after a theme update the customizations need to be installed again.

Outcome

The store now runs on a Shopify 2.0 theme with sections on every page, a welcome that routes visitors into the right universe, and a set of features the team can manage through metafields and the theme editor.
