Expert Advice

We love sharing what we know, so here’s some
information we think you’ll find useful.

  • About us


    Our company was incorporated in October 2007 as Diamond manufacturers. Founder and CEO of Vashi.com is a diamond expert, having previously been internationally trading diamonds wholesale since 1999. Our partner companies have been in the diamond business for several generations. Thanks to our vertical integration with sightholders of the Diamond Trading Company (DTC), the world's largest diamond miner, we benefit from the best contacts available in the industry. Vashi.com was launched in September 2013 as part of a rebrand of DiamondManufacturers.co.uk.

    Do you make custom jewellery?

    Yes. At Vashi.com, we are always delighted to work with you to make a complete bespoke piece. We can create it from a single image – just for you. Whatever your preference or budget, anything is possible. All our bespoke items are handmade, expertly crafted in London, England. We only use precious materials of the utmost quality to create your dream bespoke piece. We are generally able to create bespoke items in just a few days, although timeframes can be slightly longer depending on the complexity of the piece.

    Are you open on weekends and bank holidays?

    How do you source your diamonds?

    As Vashi.com we deal directly with sightholders of the DTC, which control almost half of the world's diamond production. We buy our diamonds in large quantities first hand in, directly from these cutters in Antwerp, Tel Aviv, New York and Mumbai, allowing us to hand-select only the most beautiful, high quality stones. We eliminate the middleman to control quality and deliver the best value to you.

  • Customer Service

    How long does it take for someone to get back to me when I submit a request?

    If you submit your request during office hours (9am-6pm Monday to Friday) you should receive a response within an hour from your request. If you submit your request outside office hours, one of our engagement ring and diamond experts will get in touch with you as early as possible the next morning.

  • General

    What are synthetic diamonds?

    Synthetic diamonds are man-made diamonds or lab-created diamonds with the exact same properties as a natural diamond. There are 2 types of lab-grown diamonds – High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). The HPHT process mimics the geological conditions that create natural diamonds. It grows diamond layers on a diamond seed by subjecting carbon to high pressure and high temperature. The CVD method is a revolutionary process that is the exact opposite of HPHT. Instead of pressuring carbon into diamond, the carbon is freed to become pure diamond. Moderate heat is applied to a carbon cloud in a vacuum chamber causing diamond atoms to rain onto and grow a diamond seed. Synthetic diamonds are mainly used for industrial purposes. Although they appear very similar to natural diamonds these must not be confused as synthetic diamonds are less valuable both emotionally and economically. Lab-grown diamonds are not to be confused with simulants (diamond imitations) such as Cubic Zirconia and Moissanite.

  • Products and Sizing

    How can I purchase one of your diamond rings?

    You can purchase any of our diamond rings securely online. If you incur any issues, please contact customer service at service@vashi.com for further support.

    How do I establish the ring size I require?

    If the purchase is a surprise, simply take the internal diameter of one of her existing rings and let one of our engagement ring and diamond experts know. If you are unable to do this, you can contact us to request a free ring sizer. Once you have confirmed the correct size - you can usually do this at your local jeweller, you can return it to us and we will resize it for you, free of charge- please see exclusions.

    Resizing Exclusions:

    • Rings can only be resized within the existing available size range. For example, a ring with sizes available of M-P can only be resized within that range.
    • Solitaire rings can only be sized 3 sizes either way from the original size for free. A resize outside of this range will incur a £40 fee (inclusive of VAT).
    • Rings which feature side stones will need to first be assessed by our workshop in order to obtain a quote for the cost of resizing due to the delicate nature of such work.
    • Certain rings, depending on their design, can be resized only 2-3 times in the ring’s lifetime.
    • Rings are non-returnable for refund or exchange once they have been resized.
    • After your first free resizing, any further resizes will be charged at £40 (inclusive of VAT).
    • If your item has been engraved, any re-sizing is subject to a £40 charge. Your engraving may fade in the resizing process - any re-engraving you may request will be charged at £4 per character.

    I would like to engrave a message on the ring, can you do this?

    Yes, we can engrave the message that you wish. We currently offer free engraving on all plain wedding bands. Your inscription is limited only by space and your imagination. Although the traditional place for an engraved message is the inner surface of a ring the outer surface can also be engraved. Popular ideas for inscriptions include:

    • His and her initials or names
    • Significant dates e.g. first date, marriage etc.
    • Meaningful words such as "eternity" or "always"
    • A (short) line of poetry or lyrics
    • Some statement of special significance to the two of you.

    At Vashi.com we recommend you keep a note of the inscription. They can be very helpful in getting your ring back if it is ever lost or stolen.

    Do all products carry a hallmark?

    Yes. All our products come with British hallmarks, stamped at the London Assay Office.

    Does my piece of jewellery come with a valuation?

    Yes. Every piece of jewellery is supplied with a valuation for insurance purposes as well as a diamond certificate.

    How do I know if your diamonds are conflict-free?

    When in doubt, ask your jeweller for a written guarantee. This has to be passed to your jeweller by the suppliers, if the jeweller doesn't have one then he cannot be certain that the diamonds are conflict-free.
    As at Vashi.com we deal directly with sightholders of the DTC (The Diamond Trading Company), the world's largest diamond miner, we can pass to you the conflict-free guarantees which are provided to us. We only deal with our associated companies whom, like us, proudly adhere to and enforce the standards established by the Kimberley Process, an international system that polices the trade of diamonds to ensure they are from sources free of conflict.
    All Vashi.com diamonds are guaranteed to be conflict free. If one of our associates was ever found to be in violation of that process, we would immediately stop working with them. We will continue to support and promote any process that works towards maintaining the human rights and best working conditions in the diamond trade. Vashi.ie is a global strong conflict-free supporter and has a zero-tolerance policy toward conflict diamonds.

    What do I need to know about conflict-free diamonds?

    As a consumer, you should feel good about your diamond purchase. Make sure that the jeweller is willing to spend time providing the information you need. A reputable jeweller should:

    • Only use suppliers who can provide a written guarantee that their diamonds are from conflict-free sources
    • Have a policy in place against conflict diamonds
    • Be able to answer your questions about the topic

    Ask questions to get the assurance you need. At Vashi.com we recommend you ask the following questions:

    • How can I be sure that none of your jewellery contains conflict diamonds?
    • What is your company's policy against conflict diamonds?
    • Do you know where the diamonds you sell come from?
    • Can you provide me a written guarantee with my purchase stating that the diamonds supplied are conflict-free?

    Where do your diamonds come from?

    At Vashi.com we deal directly with sightholders of the DTC, the world's largest diamond miner, and we still can't tell from which mine each diamond comes. In fact, nobody can, as diamonds don't come with such information and they are then mixed and assorted before they are cut and polished. Most of our diamonds come from mines which are located in South Africa, Canada and Australia, and are cut and polished in Belgium, India and Russia.

    Are your diamonds enhanced?

    No. All our diamonds are natural and have never been treated or enhanced in any way. Beware of buying a diamond that may be fracture-filled to temporarily inclusions or laser-drilled to remove dark inclusions. These diamonds are no longer natural as they have been treated, and the treatment generally will deter with time. A non-treated natural diamond is a lifetime investment because it never changes, it's the only product in the market which can never be classed as used. At Vashi.com, we refuse to sell any kind of enhanced diamonds including but not limited to Fracture-Filled or Laser-Drilled diamonds.

  • Our products

    Are all your ring styles listed online?

    If you can't find a style, please contact us and we promise to beat any quote you have been given by any reputable jeweller or online store.

    Do you have the same style rings in different sizes?

    We stock most of our rings in a variety of sizes. If for any reason your ring size is not available, we'll gladly resize it for you. As finger sizes can change over time, we offer free resizing for life.

    How do I know how a diamond will look?

    We hand inspect every loose diamond, setting, and piece of jewellery we sell. At Vashi.com quality isn't a compromise, it's a guarantee. You'll get the best value available in the market. 
Every diamond is carefully inspected, and hand selected in the major diamond manufacturing centres. All our diamonds, regardless of the specifications, are top quality for maximum brilliance and sparkle. 

    Every Vashi.com diamond has been hand selected for its visual beauty. Every diamond has its own unique characteristics, as diamonds are like snowflakes or fingerprints; each with its own sparkle and appearance. We invest a lot of time to thoroughly examine every diamond that we carry - after all it is how the diamond looks, not just how it scores on a certificate that is important.

  • Packaging

    How is my jewellery packaged?

    At Vashi.com we believe that packaging should be both discreet and beautiful. Discreet so that you can keep the surprise until your desired moment, beautiful to really 'wow' the lucky recipient. 
Your order will be delivered in an unbranded, large white cardboard postal box. Open this large box and you will find a luxury gift box. You can open the large white box and gift-wrap the small box yourself. In addition, you can also include a gift message of your choice for free.
