1. The 77 Diamonds Price Guarantee

At 77 Diamonds, we understand price is important, and that’s why we are determined to get it right for our customers. More than being never knowingly undersold, we go a step further.

We regularly check the prices of our competitors to ensure that we always offer the best quality for the price in the market. If you see a diamond or a piece of diamond jewellery at 77 Diamonds and you then find the exact same item available at a lower price from one of our competitors, we guarantee that we will not just match that price, we will offer you a price that is 1% lower up to a maximum value of £50/ €55 /USD $80 lower. Please note the Price Guarantee is not valid in conjunction with any other promotion/sale.

If you would like to apply the 77 Diamonds Price Guarantee, please email us and tell us the website address or shop where you saw a lower price.

up to 71% better value than high street

In order to demonstrate that we provide you outstanding value relative to the high street, we regularly conduct research into high street competitor pricing. In November 2014, we conducted a mystery shopping trip and visited a range of competitors in-store including H. Samuel, Ernest Jones, Wempe, Tiffany & Co*, De Beers and Boodles. We asked them to quote on a range of GIA diamonds and compared that to the equivalent price of GIA diamonds on 77 Diamonds website**. We found that we were between 30% to 71% better value or on average 52% better value across the entire range of diamonds and stores.

*We assume Tiffany graded diamonds are equivalent to GIA.
** Allowing for the cost of the ring where applicable

How do we do it?

The 77 Diamonds Price Guarantee is possible because our diamonds, all of which are conflict-free, come to us directly from the manufacturer that polished them. This enables us to skip out the usual journey of diamonds– from the diamond mine, to the diamond dealer, to a wholesale jewellery store. It also explains why most of our diamonds come with certificates dated only a few months ago.

2. The 77 Diamonds Certificate Guarantee

Diamond certificates detail the specifications of a diamond and are an assurance of diamond quality. At 77 Diamonds, we guarantee that each diamond you select comes with a certificate from one of the five most trusted independent laboratories in the world - the GIA, AGS, HRD, IGI or EGL. You may find some of our competitors produce their own certificates. At 77 Diamonds, we only offer diamonds with certificates from the strictest and most recognised grading laboratories in the industry. This excludes side stones and small stones on selected items of jewellery where a valuation certificate is provided instead.

3. The 77 Diamonds Diamond Information Guarantee

At 77 Diamonds we guarantee that on our website we provide the full details for every single diamond in our stock with its precise specification and the source of its certificate.

4. The 77 Diamonds Money Back Guarantee

If you are not satisfied with a diamond or piece of diamond jewellery you have bought from 77 Diamonds, you can send it back to us within 30 days and we guarantee we will send you 100% of the purchase price back, no questions asked (see our T&Cs).

5. The 77 Diamonds Lifetime Production Guarantee

Your 77 Diamonds jewellery comes with a lifetime warranty that covers any manufacturing defects and any necessary repair will be conducted free of charge under the following terms and conditions:

  • The item is identified by our production department as being defective as a result of a manufacturing default.
  • The item has not had any damage as a result of mishandling or Inappropriate impact (eg. knocks, dents or pressure), and has had no alteration, manipulation, repair or care by a service provider apart from 77 Diamonds or is the consequence of normal wear and tear.
  • Proof of purchase must be presented.

6. The 77 Diamonds Free Resize Guarantee

77 Diamonds is pleased to offer the first resize of any ring purchase for free as long as the resize takes place within the return policy range. Rings can only be sized 3 sizes either way from the original size for free. A resize outside of this range will incur a £45 fee (inclusive of VAT).

7. The 77 Diamonds British Manufacturing Guarantee

With a showroom in the heart of Mayfair and our workshops also based in Central London, we are extremely proud to be a British company that produces and manufacturers our jewellery within the United Kingdom. It is for that reason that all our jewellery is hallmarked by UK assay offices.
