Size Guide

Measure your finger

Use items you have at home to get the perfect fit.

How to measure your finger with string

Timing is key: Measure your finger in both the morning and the evening for the most accurate result.

The ideal balance: Your ring should feel secure enough to stay in place, yet glide over your knuckle without resistance.

Deciding between sizes: If you aren't sure which to pick, it's usually safer to go with the larger size.

This will give you the ring circumference which you can enter into the calculator below.

Cost Delivery time
UK Standard (Royal Mail) £5, free over £150 2 to 4 working days

All orders ship tracked, and a signature is required on delivery for domestic and international express services. International orders are handled by our logistics partner Global-E.

When will my order be dispatched?

Orders placed before 3pm on a working day are dispatched the same day. Orders placed after 3pm, or at weekends and on UK bank holidays, are dispatched on the next working day. If you need the express next-day guarantee specifically, place your order before 1pm.

You will receive a dispatch email with a tracking number as soon as your parcel leaves. If you have not had that email within 2 working days of ordering, check your spam folder first, then email hello@heavenlylondon.com with your order number.

How do I track my order?

Your dispatch email contains a tracking number and a link to follow your parcel. UK orders ship with Royal Mail, and international orders are tracked through our logistics partner Global-E.

Tracking can take up to 24 hours to show its first scan after dispatch, which is normal and does not mean the parcel is lost. If tracking has not updated for 5 working days, email hello@heavenlylondon.com and we will open a case with the carrier.

How do I return an item?

Start a return within 21 days of receiving your order through our returns portal, or email hello@heavenlylondon.com with your order number.

Items must be unused, in their original condition and original packaging. Return shipping costs are deducted from your refund, and we do not accept returns on earrings, for hygiene reasons. Sample sale items are also non-returnable.

How long do refunds take?

Once your return arrives and has been inspected, your refund is processed within 10 days, back to your original payment method.

Return shipping costs are deducted from the refund amount, in line with our returns policy. If your item was faulty or not as described, this does not apply, contact us and we will cover the return cost.

Can I exchange for a different size or piece?

Return your original item within 21 days through our returns portal and place a new order for the item or size you would prefer, so your replacement does not wait on the return being received first.

Return shipping costs are deducted from your refund on the original item, the same as any other return. See our choosing your piece FAQ for help finding your size before you reorder.

Which items cannot be returned?

Earrings cannot be returned at all, for hygiene reasons, regardless of whether the packaging has been opened. Sample sale items are also non-returnable.

Gift cards are non-refundable. Nothing here affects your statutory rights if an item arrives faulty or is not as described, in which case we will repair, replace or refund it regardless of category.

Will I pay customs or import duty on an international order?

Possibly, depending on your destination. Import duties and taxes on European and rest-of-world orders are the recipient's responsibility, and are handled through our logistics partner Global-E.

Since the UK left the EU, EU deliveries are subject to local VAT above each country's de minimis threshold, set by the destination country rather than by Heavenly London. Check your order confirmation for what has been included.

What happens if my order arrives damaged or faulty?

Email hello@heavenlylondon.com as soon as possible with your order number and a photograph, and we will replace, repair or refund the piece and cover the return cost.

Under the Consumer Rights Act 2015 you have 30 days to reject a faulty item outright for a full refund, and up to six years in England, Wales and Northern Ireland to claim for a fault that was present at purchase. Our six-month warranty sits alongside those rights and does not replace them.

How is my order packaged?

Every Heavenly London order is packaged in FSC-certified cardboard, which guarantees the card comes from responsibly managed forests, with each piece gift-ready in its own pouch or box.

Outer bags are made from 80% recycled plastic and are fully recyclable, and parcels are sent in plain outer packaging with no pricing visible inside, so an order can be sent directly to a recipient.

My Ring Sizers arrived very quickly after ordering them, they are perfect & do the job well - the website was very user friendly & the product was a great price would definitely order from this Company again & would highly recommend it to family & friends

The Magic Universal Ring Resizer - makes rings smaller!

These are a great solution for rings that are a bit too big. Also great that you get x3 in a pack due to differing ring band widths. A great ‘temp solution’, whilst weight stabilises. Silicone is prone to sliding around shank/band of ring. Otherwise would recommend.

The Magic Universal Ring Resizer - makes rings smaller!

This little spiral is genius. It’s saved me trying to get a lovely inherited antique ring made smaller, which would probably not even be possible. So easy to slide onto your ring , stays in place without moving and sits at the back where you can see or feel it. My lovely ring I can’t now wear without it spinning and the worry of losing it. And you don’t just get one ring resizer, there were 5 little individual spirals of different widths for slim or wide band rings. At £4 it is an absolute bargain, the price of a takeaway coffee !!! Thank you ladies for this fabulous little ingenious spiral, perfect to keep on standby for any rings that might begin to feel loose.

Our Story

Heavenly London began the way the best things often do, quietly, and with love.

In 1993, my mum started the brand from her home in London, selling hand-crafted necklaces through a mail order catalogue. I grew up surrounded by the pieces, the passion, and the care that went into every order. When the time came, I carried it forward.

Today, Heavenly London is built on a simple idea: beautiful jewellery, made better. We specialise in lab-grown diamonds, moissanite and exceptional alternatives to mined stones. Pieces designed to last, and to be worn every day.

B Corp Certified

We are proudly B Corp certified, and have worked with the same trusted suppliers for over 30 years. It’s a rare kind of consistency, and one we don’t take lightly.

At its heart, Heavenly is still small and personal. I design every collection myself, and our pieces are packed by a tiny team, just as they always have been.

Perhaps that’s why they’ve found their way into the jewellery boxes of women all over the world, including a few you might recognise.

Over thirty years on, not much has changed.

Still made with love.

Still Heavenly.
