Frequently Asked Questions

About Us:
Why are you called 77 Diamonds?

In 1477, the first diamond ring was given as a gesture of “will you marry me” by Archduke Maximillian to Mary of Burgundy. 1477 was too long so we shortened it! Also 77,000 miles per second is the speed at which light passes through a diamond.

How long have you been in business?

The company was formed in 2004 and we will shortly be celebrating our 15th anniversary.

Where is your Mayfair Showroom located?

We are located on the 2nd floor of Harbridge House, 3 Hanover Square, London W1S 1HD (above Citi Bank).

What are your opening hours?

We are open 10am-7.30pm Monday – Thursday, 10am – 6.30pm on Fridays and 10am-5pm on Saturday. We operate a by appointment only system in our showroom so contact us on +44 203 540 1477 to book an appointment.

 

Diamond Information:

Regarding pricing: in what currency is your price list fixed? Does it also fluctuate in accordance with underlying diamond market prices?

Diamond prices are listed in accordance to the dollar so can fluctuate on a daily basis as the dollar rate shifts – but by a marginal amount. Our prices are constantly checked to ensure they are harmonised with the current diamond market.

Where do your diamonds come from?

We source diamonds from all over the world from diamond manufacturers that comply with the United Nations Kimberley process in order to affirm all stones are conflict free.

Why do you sell these diamonds if they’re yellow/brown and have visible inclusions?

Some stones that are not suitable for engagement rings may be suitable for other uses – such as being set in jewellery where the inclusions aren’t as visible – such as earrings, or setting in yellow gold where the colour isn’t as noticeable.

Is surface graining an issue?

Surface graining is something that is only visible under microscopic magnification and all diamonds have some form of surface graining.

What does "additional pinpoint not shown" mean?

This means that within the diamond there is a minute pinpoint within the stone that is too difficult to mark on the reference diagram because of its small size.

What does "additional clouds are not shown" mean?

This means that there are clouds within the stone that are again too small to be highlighted on the reference diagram.

The date on my GIA certificate: What does it mean?

This is the date from when the diamond was certified.

Do you sell second hand diamonds?

None of the stones we sell are second hand diamonds.

Why is there a price difference between these diamonds (all same cert and specs)?

Because we source from such a high percentage of the global diamond market, some diamond manufacturers are priced differently to others – essentially the items will be identical but they are just priced differently!

What are the differences in the certifications?

In general, EGL is not as strict as GIA and can be two or three grades lower in both colour and clarity, and you may find a colour and /or clarity grade difference if the same diamond was sent off to GIA. Due to this, diamonds graded by EGL can be found at lower prices, as a colour and clarity grade difference can make up to 15-25% difference in price. In general, a diamond is sent off to EGL when a manufacturer believes they have a borderline diamond and want to achieve the higher grading. However, EGL diamonds can offer tremendous value and the quality will be beyond question as long as the clarity is VS1 or above and the colour is F and above (the diamond will be colourless and have no visible impurities).

How are the diamonds sourced?

We source our diamonds directly from the manufacturers that polish the stones.

Do you sell both natural and lab-grown diamonds?

Yes, we sell both. Lab-growns are a more affordable option when it comes to loose diamonds. Depending on size, colour and clarity, these diamonds can be more than 50% less expensive than a natural stone.

How I can be sure that you are selling conflict free diamonds?

The diamonds as advertised on our website have been purchased from legitimate sources not involved in any funding conflicts. Please note that these stones are in compliance with the United Nations Resolutions and the Kimberley process. We at 77 Diamonds guarantee that our diamonds are conflict free based on personal knowledge and/or written guarantees.

Can I arrange a viewing of the diamond before it is set in the jewellery?

Once your diamond has arrived in our showroom prior to setting we can definitely arrange for you to view the stone before it is set into the jewellery.

What clarity grades are considered to be eye clean?

With GIA certified diamonds, IF, VVS1, VVS2, VS1 and VS2 are considered eyeclean with a smaller percentage of SI1 and SI2 stones also being eyeclean.

With EGL certified diamonds, IF, VVS1, VVS2, and VS1 are considered eyeclean with a smaller percentage of VS2 and SI1 stones also being eyeclean.

Contact our sales team who can verify the stone’s clarity for you.

What is fluorescence exactly?

Diamonds that are said to be fluorescent contain particles that emit a visible (usually blue) glow when exposed to UV lighting. In rare cases, high levels of fluorescence can make stones appear milky or hazy, although for the most part fluorescence does not generally impact beauty or sparkle and can even make some lower colours (I, J, K, L, etc.) appear more colourless or white.

 

Jewellery Information:
Why does the price increase when the ring size is above N for an Eternity ring?

The additional cost covers the extra metal weight and any additional diamonds.

Why do you charge customers £ 100 for rushed orders?

If we are able to expedite your order, the small fee is required to prioritise your jewellery in our workshop.

Why do some rings require a CAD drawing to be produced?

We need to CAD some jewellery designs in order to realise the proportions needed prior to casting – changing a jewellery piece after it is cast is a difficult and expensive process.

Why do your vintage styles take 5 weeks to be produced?

Because of the intricate nature of some of our designs there are a few of our rings that take 5 weeks to produce because they are cast to order based on the finger size (if known) and the measurements of the centre stone chosen and all the side stones are hand set.

Do you offer a bespoke service and how does this work?

Should you have a particular jewellery design in mind that does not currently exist in our jewellery collection, you can contact our designer with your ideas who will then discuss with you directly the options for your piece and provide you with a quote.

What are your lead times?

The majority of our items take approximately 15-20 working days with some of our more elaborate pieces taking 5-6 weeks. Should you have a particular deadline in mind, you can always contact us and we can check to see if this can be accommodated.

Can I add an engraving to my ring?

Yes engraving is priced at £ 35 per ring(inc VAT) with the maximum of 12 characters, you can also choose from a selection of fonts. Contact our sales team directly to provide you with the font list.

Is your jewellery hallmarked?

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:

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

What metals do you use?

We offer the majority of our jewellery in 18k Gold (white, rose and yellow) and Platinum.

Because of the density of platinum there are some more intricate pieces that cannot be produced in Platinum. Some of our wedding bands are also available in Palladium.

What metals can be plated?

All our gold jewellery can be plated when this is necessary.

Why does White gold get a yellow hue?

White gold is plated with rhodium which is part of the Platinum family and gives it a distinctive shining white appearance, as white gold in its natural state is actually darker and duller. For this reason, it is recommended to have a white gold engagement ring periodically re-plated when its colour is beginning to fade.

What is the difference between Platinum and White Gold?

When newly produced, both Platinum and White Gold are the same in appearance. Platinum is a denser metal so therefore feels a little more substantial in weight. White gold is less prone to surface scratches than Platinum, but in turn would need replating.

Can you manufacture your jewellery with stones other than diamonds?

We have made our jewellery with many kinds of gemstones and semi precious stones in the past, contact us directly if you have particular request and we can try to accommodate it.

How long does a resize take?

Resizing takes approximately 10-15 working days from the day we have received your item.

What if I order the wrong ring size?

Not to worry! Your first resize is always free of charge if within your 30 days exchange policy. (see section 8 of the T&C for more details) and you can come into the showroom to size the finger correctly or alternatively you can check at a local jewellers and then send the ring back to us.

What payment options do you offer?

How are you 75% cheaper than the high street?

In November 2013, 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 37% to 75% better value or on average 56% 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 does the best price guarantee work?

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 diamond 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 lower*.

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.

This service is called an MIB (Merchandise In Baggage) and costs £200. Once you pass airport customs, one of our consultants will be waiting for you and will hand you your item tax-free. To qualify for this service, you must be flying out of the UK and reside in a different country.

Overseas customers purchasing from our showrooms in Germany can claim back German VAT at the airport upon leaving the country. You will need to notify our team upon purchasing your item, and we will hand you a reclaim form to present at airport customs.

Will Brexit affect my order?

As a company proudly based in Europe with legal entities in both Portugal and Germany, we are pleased to inform our customers that services will continue with little to no changes.

Europe now accounts for half of our transactions and, following this deal, we expect this to become a majority. We are, as ever, fully committed to providing the same level of service to all our customers, whether based in the UK or the EU.

Customers based in the EU will now be charged VAT on their purchase once it arrives in their country of residence, instead of paying VAT at checkout as was the case before Brexit. Local VAT rates will apply and there may be some import duties depending on the item you purchased. In the rare event that you are charged import duties, 77 Diamonds commits to refunding these duties in full.

Please contact our customer services if you are unsure whether your selected item is duty free. You can also contact your local customs office for further information on VAT and import duty rates.

Please note, the above does not apply to customers based in Germany, Denmark, Switzerland and Sweden, who will continue to have VAT added at checkout. Furthermore, customers based outside the EU will pay both VAT and duties on their purchase, these are non-refundable.
