How to Sell Diamonds Online: A Practical Guide for Jewellers
A clear, end-to-end guide for independent jewellers who want to sell diamonds online — the two business models, what you actually need, what it costs, and how to launch without a £40,000 custom build.
Selling diamonds online used to belong to a handful of national retailers with big engineering teams. It does not any more. An independent jeweller can now put a full, live diamond catalogue on their own website — with real prices and certificates — without holding stock and without a five-figure build.
This is the practical, end-to-end version: the decision that comes first, what you actually need, what it costs, and how to launch. Each section links to a deeper guide if you want to go further.
Full disclosure: NivoSync is our plugin, and it is one way to do the technical part. The path below is useful whatever you build with.
The hard part was never knowing diamonds — it was inventory and engineering. A marketplace feed removes the first, and a plugin removes the second. What is left is a decision and an afternoon.
Step 1 — Decide your model: hold stock, or don't
This is the decision everything else hangs on.
- Hold your own stock. You buy diamonds, photograph them, list them, and carry the capital and risk. Full control, but you can only ever show the few stones you own — and tying up cash in inventory is exactly what keeps most independents small online.
- Sell from a live marketplace (no stock). You list stones you do not own; when a customer buys, the diamond is sourced, quality-checked and shipped through the marketplace's logistics. You carry no inventory and no capital risk, and you can show hundreds of thousands of stones.
For almost every independent selling online, the marketplace model is what makes it viable — it is the whole reason this is now realistic. Nivoda is the B2B marketplace most jewellers use for this, covering natural and lab-grown stones with its own fulfilment.
Step 2 — Choose where it lives (your platform)
You need a website you control. For most jewellers that means WordPress with WooCommerce — it is the most common, flexible and affordable option, and it keeps you off a closed platform you cannot fully own. (If you already have a WordPress site, you are most of the way there — see how to add a diamond catalogue to WordPress.)
You do not need to become an online store overnight, either. A brochure-style jewellery site can show a live, priced diamond catalogue and take enquiries without a full checkout — and add WooCommerce later when you are ready to sell online directly.
Step 3 — Get a live catalogue onto your site
This is the part that used to cost £15,000–£40,000 from an agency. A plugin now does it: NivoSync connects the Nivoda feed to WordPress and puts the full inventory — often 200,000+ stones — on your site as a searchable catalogue with real-time prices, filters and single-diamond pages. (Here is how that looks on WooCommerce specifically.)
The thing to understand: the catalogue reads from a cached copy of the feed, so it is fast, and your markup is applied automatically on top of the wholesale price — so the prices your customers see are your retail prices, not Nivoda's cost.
Step 4 — Build trust: certificates and detail
A diamond is a high-value, emotional, mostly-online-researched purchase. Trust is the whole game, and two things carry it:
- Certificates. Every stone should show its grading lab (GIA, IGI) and report number, with a way to verify it — see how to show GIA and IGI certificates on your site.
- Detail. 360° views, full specs, clear imagery. This is what turns "nice photo" into "I can see exactly what I'm buying."
Step 5 — Help customers choose (ring builder)
Most diamond buyers are really buying an engagement ring, not a loose stone. A ring builder lets them pick a setting and a diamond and see the finished ring — and it measurably lifts conversion and order value. If engagement rings are your market, this is not optional for long.
What it costs
Honestly: far less than it used to. The old route was a £15,000–£40,000 custom integration, then ongoing maintenance. The plugin route is a yearly licence a fraction of one agency quote — the full breakdown is in how much it costs to sell diamonds online and on the pricing page.
Build it yourself, or buy it?
If you have a developer, you can wire up the Nivoda API directly. For almost everyone, a ready-made plugin is faster, cheaper and someone else's problem to maintain — the honest comparison is in Nivoda API vs. a ready-made plugin, and if you are weighing data sources, Nivoda vs VDB vs RapNet.
You are now competing with the big names — on fair terms
Once a live catalogue is on your own domain, you are no longer losing customers to the national online retailers just because they had the inventory online and you did not. You match them on selection, and you beat them on the thing they cannot offer: a real, local, trusted jeweller. That full argument is here: how independent jewellers can compete with Brilliant Earth.
The short version
- Choose the no-stock marketplace model (Nivoda) so you can sell without carrying inventory.
- Put it on WordPress / WooCommerce, a platform you own.
- Add a live catalogue with a plugin instead of a £40k build.
- Show certificates and detail to earn trust.
- Add a ring builder if you sell engagement rings.

Frequently asked questions
Can I sell diamonds online without holding inventory?
Yes — that is the point of the marketplace model. With Nivoda you list stones you do not own; the diamond is sourced and shipped through Nivoda's logistics only once a customer orders. It is what makes it practical for an independent jeweller to offer hundreds of thousands of diamonds online.
Do I need WooCommerce to start?
Not necessarily. You can show a live, priced diamond catalogue and take enquiries on a standard WordPress site without a full checkout, then add WooCommerce when you want to sell and take payment online directly.
How much does it cost to set up?
Far less than the £15,000–£40,000 agencies have historically quoted for a custom Nivoda integration. A plugin replaces that with a yearly licence — see the cost guide and pricing page.
How long does it take to go live?
The build is a plugin install and a sync, not a development project — a jeweller can have a live diamond catalogue on an existing WordPress site the same day.
Can I sell lab-grown diamonds too?
Yes. Lab-grown stones are available on the same marketplace and display the same way — here is the guide to selling lab-grown diamonds online.
