How to Add a Diamond Catalogue to WordPress (2026 Guide)
Four ways to put a searchable diamond catalogue on a WordPress site — manual entry, CSV import, the supplier API, or a dedicated plugin — with the trade-offs of each.

Adding a diamond catalogue to WordPress sounds simple until you realise a real diamond inventory changes by the hour and can run to hundreds of thousands of stones. This guide covers the four practical approaches and where each one breaks down.
The four ways to do it
1. Manual product entry
Create each diamond as a WooCommerce product by hand.
- Good for: a tiny, stable selection (say, under 50 signature stones).
- Breaks down when: your catalogue is large or prices move. Manual entry cannot keep up with live diamond pricing, and stale prices lose sales — or margin.
2. CSV import
Export a supplier spreadsheet and import it into WooCommerce.
- Good for: an occasional bulk load.
- Breaks down when: you need freshness. A CSV is a snapshot; by tomorrow it is wrong. You also lose rich media (360° video, certificate data) and re-importing thousands of rows is slow and error-prone.
3. The supplier API
Connect directly to your supplier's API — for example, the Nivoda API — and build your own integration.
- Good for: teams with development resources and unusual requirements.
- Breaks down when: you count the true cost. Authentication, pagination, caching, currency and pricing rules, image handling, search, and ongoing maintenance are all on you. We cover this in detail in Nivoda API vs. a ready-made plugin.
4. A dedicated plugin
Install a plugin that syncs the catalogue into WooCommerce for you.
- Good for: almost every retail jeweller who wants a live catalogue without a development project.
- Breaks down when: rarely — provided the plugin handles sync, pricing, search and display properly.
Trade-offs at a glance
| Approach | Handles large catalogues | Stays live | Needs a developer |
|---|---|---|---|
| Manual entry | No | No | No |
| CSV import | Partly | No | No |
| Supplier API | Yes | Yes | Yes |
| Dedicated plugin | Yes | Yes | No |
Which should you choose?
If you are showcasing a handful of hero stones, manual entry is fine. For a real, live catalogue — the kind customers expect when they shop for a diamond online — you need either the API (if you have developers) or a plugin (if you do not).
For WooCommerce specifically, NivoSync syncs a full diamond catalogue, applies your own pricing and markup, and ships with search, filtering and a ring builder out of the box. If your inventory comes from Nivoda, start with how to sell Nivoda diamonds on your WooCommerce store.
Frequently asked questions
Can WordPress handle a large diamond catalogue?
Yes, with the right setup. The trick is to cache the catalogue locally and render it efficiently rather than calling a live API on every page load — which is how a purpose-built plugin handles it.
Do I need WooCommerce?
For selling, yes — WooCommerce provides the cart, checkout and order handling. A diamond plugin layers the catalogue, search and ring builder on top.
How do I keep prices up to date?
Automatically. Manual and CSV methods drift out of date; an API- or plugin-based sync refreshes pricing on a schedule so what customers see is what they pay.
