Frequently Asked Questions

About Us:

  • How old is the company and how did it begin?

    77 Diamonds is now 10 years old, it began when our two founders met. One with a history in banking and one with a family heritage in diamonds – two business minded entrepreneurs with complimentary backgrounds and the same ambition; to create a world class diamond jewellery business with an unforgettable customer experience.

  • Why are you called 77 Diamonds?

    In 1477, the first diamond ring was given as a gesture as “will you marry me” by Archduke Maximillian to Mary of Burgundy. 1477 was too long so we shortened it! Also 77,000 MPH 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 10th 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 0203 540 1477 to book an appointment.

Diamond Information:

  • Regarding pricing: in what currency is your price list fixed? Does is fluctuate also due to 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 marginal amount.

  • 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 means?

    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 means?

    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 different between these diamonds (all same cert and specs)?

    Because we source from such a high percentage of the diamond 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.

  • Are you only selling natural or synthetic diamonds?

    All the diamonds sold by 77 Diamonds are 100% natural stones.

  • 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 weight in gold and the diamonds

  • Why do we charge customers £40 for rushed order

    We are willing to prioritise your order for you and the small fee is required to expedite your order in our workshop.

  • Reason why ring needs to be CAD?

    We need to CAD some rings in order to realise the proportions needing prior to casting – changing a ring after it is cast is a difficult and expensive process.

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

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

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

    We do offer our bespoke service, should you have a jewellery design in mind that currently does not exist on our website you can contact our designer with your ideas who 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 10-15 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 on the ring?

    Yes, you can, engraving your ring with your chosen text is priced at £25 (inc VAT) and you can choose from a selection of fonts. Contact our sales team directly to provide you with the font list.

  • Where is your jewellery 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

  • What metals do you use?

    We offer the majority of our jewellery in 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 jewellery with other stones than diamonds?

    Yes of course, we have made diamonds with many kinds of gemstones and semi precious stones in the past, contact us directly if you have particular request.

  • How long does the resizing take?

    Resizing takes approximately 3-5 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 (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.

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.
