Frequently Asked Questions

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.

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

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

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 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.

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.

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.

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

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.

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

This is the date from when the diamond was certified.

None of the stones we sell are second hand diamonds.

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!

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).

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

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.

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.

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.

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.

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.

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

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

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.
