Frequently Asked Questions

At 77 Diamonds, we source our gems directly from the manufacturers who polish the stones. These manufacturers usually buy their rough diamonds from the world's main diamond producing countries, which include places such a Botswana, Canada and South Africa. We only deal with suppliers we trust, and who comply with international standards of responsible sourcing. Each diamond we sell is certified and conflict-free.

We always endeavour to offer customers enough choice in their diamond purchase, while ensuring our suppliers meet our strict sourcing standards. To this end, we regularly review and update our Responsible Sourcing Policy, and are making continual efforts to improve wherever needed.

Using some of the finest materials on earth, we craft jewel that match the brilliance of your moment. This is a privilege, but also a great responsibility. As fine jewellers, we are committed to standards of responsible sourcing. This means acting with integrity all along our supply chain, and respecting those we supply from.

Our diamonds are sourced following international standards of responsible sourcing, and come under the Kimberley Process Certification Scheme (KPCS), which ensures they have not been used to fund armed conflict.

Read more about our Responsible Sourcing Policy. This policy also extends to our coloured gemstones, lab-grown diamonds, and precious metals.

Yes, we do sell both, as we prefer our customers to have a range of diamond options directly available to them. Our diamond collection separates natural from lab-growns, to avoid any confusion. You'll also receive your gem with a certificate clearly stating that it is a lab-grown.

To make your choice as easy as possible, we recommend first-time buyers learn a little more about diamonds, and more specifically the diamond 4Cs before settling on their favourite gem. Be sure to visit our helpful diamond education section for information on how to pick a diamond. You can also contact our jewellery specialists at any time directly through live chat.

The majority of our items take approximately 15 to 20 working days to be handcrafted, with some of our more elaborate, diamond-set pieces taking up to 8 weeks (this includes vintage, halo, trilogy and diamond-set rings). If you would like to receive your jewellery sooner, we can in some cases speed up the workshop process. This, however, depends on the amount of jewellery we are working on, and on the nature of your jewellery design. Please note, there is an extra fee of £125 (around €140) included to expedite classic solitaire designs, and £175 (around €200) for diamond-set jewellery (such as halos, vintage, or trilogy designs).

For further information, please refer to our Delivery and Returns section.

Yes, we do – if you have an idea, we have the design. By sharing your ideas with our bespoke team, you can create a jewel that is completely one-of-a-kind. Send over an enquiry explaining what you would like, and attaching any images if possible. A designer will then contact you to discuss your piece, and provide you with a quote.

If you are happy with the quoted piece, our team will send you a selection of computer generated designs, and in certain cases make sketches of your jewel. Once all is approved, we will then source your chosen centre stones and send your item to be crafted in the 77 Diamonds workshop. Our team will let you know how long this will take, depending on the design's complexity.

By the way... If you like the look of one of our pieces, but feel it could be made ever better with a slight alteration – that's also possible! Whether you'd prefer to see a ring set with coloured gemstones, or would like to make a small change to a jewellery piece, simply contact our specialists to find the perfect fit.

You can engrave your ring with any message you choose for an additional fee of £30. A meaningful touch to your jewellery design, simply add an engraving to your ring before checkout. Your ring will have space for up to 15 characters, and you can choose from a range of fonts and symbols to complement your design.

Please note, engraved rings are non-returnable. Your engraving will need to be remade if your ring is resized, so best select an engraving only if you're certain you have the correct size.

Yes, we make our jewellery with a range of gemstones and semi-precious stones. You will find a selection of coloured diamonds and gemstones directly on our website. If you are unable to find a particular gem in our selection, please contact our jewellery specialists and we will source the perfect piece for you.

When it comes to manufacturing jewellery, precious metals such as gold, platinum or palladium are rarely used in their purest form. To increase their strength and enhance colour, they often need to be alloyed with a choice of metals.

As it is impossible to detect the nature of the alloy by sight alone, we have our gold, platinum and palladium jewellery independently tested and hallmarked before they are sold. All our fine jewellery items bear a hallmark at point of sale, with the following weight exemptions:

Gold and palladium: non-mandatory for items below 1 gram.

Platinum: non-mandatory for items below 0.5 grams.

77 Diamonds is registered with the London and Birmingham Assay Offices, ensuring our jewellery is compliant with the UK’s hallmarking regulations. All stock is subject to an internal confirmation process to ensure it meets the UK’s hallmarking regulations before it is dispatched to our customers.

We are an Assay Assured Jewellery Retailer. Assay Assured status is only given to retailers who have been independently audited and verified by Assay Assured which is run and overseen by the Edinburgh Assay Office, ensuring all precious metal jewellery are independently tested and hallmarked.

All our jewellery is hallmarked in the United Kingdom. You will see the following hallmarks for each metal:

Gold (Rose, White and Yellow) – 750

Platinum and Palladium – 950

You can find out what a hallmark looks like here.

We only restore 77 Diamonds jewellery to ensure the highest possible quality. Depending on your request, our bespoke team can, in certain cases, recreate a jewellery piece with diamonds or gemstones taken from a vintage piece. For minor restorations, such as replating a white gold ring or polishing your jewellery, we offer a Clean & Polish service that costs £75. This service is only available for customers who have bought a 77 Diamonds jewel.

This is simply because gold is naturally yellow in colour. To obtain a white, reflective sheen, white gold need to be alloyed with other metals such as silver, zinc or nickel, and then coated in a rare metal called rhodium. Over time, a white gold ring can lose its rhodium coating and present a faint yellow hue. Some don't mind this, but if you would like your ring to be restored to its initial lustre, you can send it to be replated by our specialists for a fee of £75. Please contact our jewellery specialists for further information.

In terms of colour, white gold and platinum are virtually identical, and both are intensely bright. So what makes them so different? The answer lies in their composition. Gold is naturally yellow in colour. To obtain that white gold sheen, gold must be alloyed with other metals such as silver, zinc or nickel, and then coated in a rare metal called rhodium. Platinum, on the other hand, is naturally white and doesn't need to be coated in any metal. In terms of pricing, white gold is more lightweight than platinum, and therefore more affordable.  

Both rings are durable, with platinum being slightly stronger and less likely to bend. Over time, you may need to replate a white gold ring as the rhodium plating can wear off. A platinum ring will sometimes need to be polished to remove any surface imperfections (known as 'patina'). You can easily do this through our Clean & Polish service which costs £65 (around 75€), and have your ring restored to its original condition. 

Ultimately, both white gold and platinum are excellent metals, and there is no wrong choice in purchasing either. To know which to choose, it’s best to understand what is more important to you: is it affordability, durability, or perhaps the amount of aftercare involved? Our team of jewellery consultants will happily guide through these options, so be sure to contact us with any questions. 

Not to worry! Ring size can be tricky, especially if you are planning a surprise proposal. This is why your first resize is always free of charge if you return your ring within 30 days. Resizing takes approximately 10-15 working days from the day we receive your item.

Please note that certain designs, such as full-set diamond eternity rings, cannot be resized and will need to be exchanged or re-made. For more information, please contact us or read our Terms and Conditions.
