Necklace Builder — Step-by-Step Custom Jewellery Configurator for Shopify

A Shopify app that lets jewellery shoppers build a necklace in three steps — pendant, centre stone, chain — and preview the assembled piece in imagery and video before adding it to cart. Stones come from a connected supplier inventory (natural and lab-grown diamonds or gemstones), with live stock availability and auto-updating pricing. Merchants can upload their own pendant, chain and gemstone designs alongside ten ready-made necklace images, managed from an admin panel. Standard plan at $199/month with a one-day trial. Launched 5 December 2025.

Necklace Builder — Step-by-Step Custom Jewellery Configurator for Shopify

A Shopify app that lets jewellery shoppers build a necklace in three steps — pendant, centre stone, chain — and preview the assembled piece in imagery and video before adding it to cart.

The brief

The challenge, and how we approached it

01

The challenge

A custom necklace isn't a product with variants — it's three products combined, one of which is a unique stone with its own certificate, price and single-unit stock sitting in a supplier's feed. Native Shopify can't model that: a diamond sold once must vanish everywhere instantly, the price must sum from live components, and the shopper needs to see the assembled result before committing to a four-figure purchase.

02

Our approach

Decompose the necklace into three sequential choices with conditional logic between them, so the chain options offered depend on the pendant chosen, and the stones offered fit the setting. Stone inventory is pulled live from a supplier feed rather than mirrored as Shopify products, with stock availability and price auto-updating so a sold diamond is withdrawn without manual intervention. Pricing is composed from the selected components as add-ons, then written to the cart as a single line so checkout stays native. Preview is image- and video-led, matching how jewellery is actually sold, with custom CSS for on-brand rendering. Merchant-uploaded designs let a jeweller feature exclusive pendants alongside the supplied catalogue. Data access is scoped to products, collections, Online Store pages and metaobject definitions — the configurator state lives in custom data, not customer or order records.

What we built

Six capabilities shipped for Dana's Bakery

Each one solves a specific part of the brief above.

ZIP-gated shipping

Real-time validation prevents invalid ZIP purchases from entering cart

Drop architecture

Pre-staged inventory with countdown, sold-out gates, and waitlist

Gifting flow

Message cards, recipient addressing, scheduled delivery, gift wrap

Perishable inventory

Daily inventory sync with cold-chain capacity constraints

Drop-day performance

Theme architecture handles 20× traffic spikes without latency

Recurring orders

Holiday subscription flow for repeat gifters

How it ran

10 weeks build, in four stages

Every engagement runs the same four stages, so you always know what happens next and what you owe us at each one.

Stage 1

Audit and scope

We review the current theme, apps and analytics, then write a fixed-scope SOW with named deliverables and a date.

Stage 2

Design and build

Work happens in a dev store on a Git-backed workflow. You get a preview link from week one, not a reveal at the end.

Stage 3

QA and launch

Cross-browser and device QA, redirect map, analytics verification, then a launch window agreed with you rather than dropped on you.

Stage 4

Hypercare

Fourteen to sixty days of included post-launch support while real traffic finds the edge cases.

The outcome

Where Dana's Bakery landed

Conversion is up 2.1× after the PDP rebuild, AOV is up 34% year-over-year thanks to gifting upsells, and drop days are now smooth — zero downtime across 12 drops in the past year.

Every drop day was a stress event before. Now they're just a Tuesday. The team built us infrastructure we can actually grow on.
