1. Just starting

Work out what you want

No idea yet? Start here. Nothing to read first.

A few quick questions about their style and how you like to shop. You get a shape, metal and diamond spec, with real Hatton Garden prices.

Match a ring on screen, measure with string, or print a free sizer. Or find someone else’s size without asking. UK, US and EU sizes.

Two diamonds, one costs more. Ten quick rounds show which grades you can actually see in a ring, and which you only see on the receipt.

Tap your birth month to see your birthstone, and whether it’s tough enough for a ring you wear every day. Add a partner’s month for a two-stone idea.

2. Comparing options

You have a rough idea. Now see what it costs and what changes the price.

Enter the amount you have in mind and see the natural and lab-grown diamond you can realistically get for it in Hatton Garden.

Put two diamond specs side by side and see the real differences in size, price and what you’d actually notice on the hand.

3. Ready to buy

You know what you want. Make sure the price is right and the day goes to plan.

Got a quote from a jeweller? Enter the specs and see how it compares with typical Hatton Garden prices for the same diamond.

Choose a shape, metal and setting and see your ring take shape. Save the design and get quotes from jewellers. Opens in a new tab.

A countdown, a checklist and London venue ideas, worked back from your date so nothing gets left to the last week.

Enter your wedding date to see which anniversary is next, its traditional and modern theme, and a jewellery idea for it.

Tap the number and symbol stamped inside your ring to see the metal, its purity and where it was tested, and whether it’s a real UK hallmark.

Today’s gold price for every carat. Enter the weight and carat of your gold to see what it’s worth and what a fair buyer should offer.
