Frequently Asked Questions

Are you open on weekends and bank holidays?
Yes. To ensure our customers receive the best possible service, our new opening hours are:

Monday to Friday 7am - 10:30pm
Saturday and Sunday 9am - 5:30pm

We are also open on public bank holidays except on Christmas day (25 December) and New Year's Day (01 January).

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 (7am-10:30pm Monday to Friday, and 9am-5:30pm on weekends) 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.

When will I receive my order?
Vashi makes every effort to get your order to you as soon as possible, and will endeavour to ensure you receive it on or before the estimated delivery date. If you need your item for a specific date please do let us know, and we will do everything we can to ensure that you receive your item on the specified date.

How do I establish the diamond 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. Alternatively, we can send you the ring in a standard size. Once you have given the ring and found 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.

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 or not?
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 we deal directly with sightholders of the DTC (The Diamond Trading Company), the world's largest diamond miner, we are able to pass to you the conflict-free guarantees which are provided to us. We only deal with our associated companies who, 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 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 is a global strong conflict-free supporter and has a zero-tolerance policy toward conflict diamonds.

Where do your diamonds come from?
It's impossible for any jeweller to say that a particular diamond comes from a specific location. At Vashi we deal directly with sightholders of the DTC (The Diamond Trading Company) - 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 hide inclusions or laser-drilled to remove dark inclusions. These diamonds are no longer natural as they have been treated, and the treatment generally will deteriorate 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, we refuse to sell any kind of enhanced diamonds including but not limited to Fracture-Filled or Laser-Drilled diamonds.

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 particular diamond will look?
We hand inspect every loose diamond, setting, and piece of jewellery we sell. At Vashi quality isn't a compromise, it's a guarantee. You'll get the best value available in the market.
All our diamonds, regardless of the specifications, are top quality for maximum brilliance and sparkle.
Every diamond has its own unique characteristics, as diamonds are like snow flakes or finger prints; 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.

How is my jewellery packaged?
At Vashi we believe that packaging should be both discreet and beautiful. Discreet so that you can keep the surprise until your desired moment, beautiful to wow the gift recipient.
Your order will be delivered in an unbranded, large white cardboard box. Open this large box and you will find a luxury wooden gift box. You can open the large white box and gift-wrap the small box yourself, or if you prefer we can gift-wrap it for you and also include the gift message of your choice. You can rest assured that our dispatch team will gift-wrap your order with the utmost care, and gift messages are printed from the message you provide to us to avoid any possible typing errors.
Needless to say, at Vashi gift-wrapping and messaging services are offered to our customers free of charge.You can select your gift preferences during checkout.

How can you offer such prices?
Our founder and managing director - Vashi Nanwani Dominguez - has been involved in the diamond business at source level for over a decade. Formerly running an international diamond wholesale company, he developed valuable contacts with sightholders of the DTC (The Diamond Trading Company), the world's largest diamond miner.
This has enabled Vashi to form supply chain partnerships with diamond cutters and one of the world's largest jewellery manufacturers and exporters. As a result, Vashi obtains its diamonds and diamond jewellery at primary source prices, and are able to pass on these savings by supplying directly to the end consumer.

How do your prices compare to other internet retailers?
Our prices are lower than on the other online stores. As you are purchasing directly from the main source we are able to pass the savings directly to you by eliminating all the traditional layers of wholesalers and retailers in the supply chain.

Do your prices include VAT?
Yes. All the prices on the website are including VAT at 20%. If your purchase is to be dispatched outside of the E.U. you will be entitled to the discount equivalent to the VAT amount.

Are there any hidden charges?
All the prices you see are final. Shipping, insurance, packaging, and gift options are all included in the price.

How do I return an order?
To return your purchase simply give us a call at 0800 530 0541 or send us an email at quoting your order number. We will respond as soon as we can, typically within the hour during opening hours. Our Customer Services Team will then send you a personalised packaging slip (via email) to include inside the parcel that you return to us. This ensures that your order is dealt with in a timely manner. We will confirm receipt of all orders via email and telephone call before the close of business on the day they arrive and further ensure that they are returned to you within five working days. We will further call and email you once your item has been redeployed so you can make arrangements for its receipt, and further have a record of the tracking number so you may trace its progress online.
Note: Vashi will not be liable for loss or damage of non-insured return shipments. We cannot be held responsible for any damage or loss you may incur as a result of late delivery or cancellation of your order, so we advise that you retain all proof of posting documentation.

What is your refund policy?
We offer a No Questions Asked 30-Day Money Back Guarantee from the date you receive your purchase. For more information please read our Returns Policy.

    About Vashi



      Welcome  and thank you for visiting Vashi (formerly Diamond Manufacturers)
      We're  really glad that you found us and we'd would love to hear from you.
        Free Phone: 0800 530 0541


      Founded in 2007 the concept behind Diamond Manufacturers was simple:
    'Offer the  Web's Lowest Prices on Engagement Rings, Diamonds and Diamond Studs'.
      Our founder and  managing director, Vashi Nanwani Dominguez, formerly run an International  diamond wholesale company which enabled us to build supply chain partnerships  with sightholders of the DTC (The Diamond Trading Company), the world's largest  diamond miner.
      We aim for the  highest quality, particularly in products with the greatest value  potential, and encourage customer criticism to continually improve the personal  service we provide to you.

          What can you expect when shopping with us?

    We strongly believe this is not a section for us to complete, but for  our customers to tell the story. After all a company is only as good as its  customers say it is.
            The comments below have been taken from the impartial feedback written  by our customers in!! the  Ring was perfect and the service was second to none best Amazon Seller I have  dealt with. Every question was answered and the packaging was exceptional,  highly recommend seller could not have asked for more 5 Star across the board.
            The best seller I have ever dealt with, so very  helpful and patient. they went above and beyond to ensure I received my item,  even with a short deadline. As for the ring.. Stunning! Very pleased.
            DO NOT HESITATE !!! Birmingham jewellery quarter,  numerous Manchester Jewellers local high street chains-dont bother. Its so easy  to get obsessive about lab certified diamonds ! But u dont wear a certificate  on your finger. We would never have afforded the spec on the high st. I adore  my ring and am complemented every day on its sparkle/clarity. Excellent  service-you will not be disappointed
            The ring is  AMAZING! It's everything they said it would be. Suffice it to say that it was  independently valuated to confirm its worth, and it was exactly what was  described. My fiancee loved it, and all her friends and family members were  speachless. I would definately recommend this seller! Can I put 6 stars  somehow?
            A smile a mile wide from my fiancee!, and rightly so.  A beautiful diamond of a quality not normally available at high street  jewelers. You can see the quality in an excellent cut and polished diamond,  sparkles aplenty! Thank you!
            This is the 1st occasion that ive ever left feedback  but i feel this company deserves it. I am delighted i with the ring i bought .I  needed it to be delivered to Spain, it arrived very quickly and well within the  time frame specified .The personnel service i received went beyond what i would  have expected . I will be using this company also in future so have no hesitation  in recommending them.
