About us

Welcome and thank you for visiting our website.

We’re really glad that you found us and we would love to hear from you.

We know how important it is that you know who you're buying from online and so we wanted to tell you a little bit about us: who we are, how our fine jewellery is made and what an outstanding service you can expect from us.

Founded in 2007 the concept behind Diamond Manufacturers was simple:

‘Offer the Web’s Lowest Prices on Engagement Rings, Diamonds and Diamond Studs’.

The company is regularly featured on radio programmes and in the national press, from the Daily Express to the Mail on Sunday.

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.

Commitment to The Highest Quality

• We buy our diamonds first hand, directly from the cutters in Antwerp, Tel Aviv, New York and Mumbai, allowing us to hand-select only the most beautiful, high quality stones.
• Because of our high standards of beauty and brilliance, we reject a very high percentage of the diamonds we examine.
• We eliminate the middlemen to maintain the highest quality and deliver the best value to you.

At Diamond Manufacturers we subject each of our products to rigorous standards of quality. Each diamond is guaranteed to have a minimum of very good sparkle, and we can guarantee this because we only stock diamonds that we have selected in person. Each piece is manufactured in our facilities using only the most premium materials and methods of craftsmanship. We carefully inspect each item to ensure that it passes our strict quality control before shipping it to you.

Commitment to The Best Value

So many websites claim to offer the best value when they simply don’t. This is something we strongly recommend you to check. The internet makes it possible for you to compare the prices of various online retailers in just a few minutes. We believe that the time you spend here is ‘time well spent’, as it will allow you to save money.

At Diamond Manufacturers we offer the Web’s Lowest Prices on Engagement Rings, Diamonds and Diamond Studs. We don’t just say this - we back every product listed in our website with a Double-the-Difference Price Guarantee.

Commitment to The Best Personal Service

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 reviews written by our customers in independent review site Review Centre. Click here if you wish to read the full reviews.

"Best Customer service I have ever experienced"

"It's all about the service for me...then value. Diamond Manufacturers had both!!..Outstanding!"

"This on-line jewellers is absolutely first class - in our view cannot be beaten. Definitely recommended."

“What we just couldn't believe was that our budget went so much further with Diamond Manufacturers than with any other of the jewellery sites.”

Why the name Diamond Manufacturers?

Because it’s what we are, Diamond Manufacturers. We’re in the diamond business because we know diamonds. Our partners are diamond cutters and they source the diamonds in rough directly from the world’s largest diamond mining companies. The diamonds are then cut, polished, and passed to us for assorting and selection.

Our diamond buyers are very demanding and we select only 1 out of 10 diamonds shown because they do not have enough visual beauty (we reject those that don't sparkle enough). We also refuse to sell stones which are very deep or shallow, the minimum cut grade we stock is Good.

How are we able to do it?

Our founder and managing director, Vashi Nanwani Dominguez, formerly ran 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.

How are we different to other diamond stores?

Unlike most other diamond websites Diamond Manufacturers does not drop ship, consign or advertise diamonds from other companies, act as a broker or advertise diamonds that are located overseas. Most other diamond websites do not own or physically hold the diamonds in stock that they have advertised online.

Most of the diamonds and all the settings displayed on the Diamond Manufacturers website are in stock, available for viewing, and delivered the next day if ordered by 3pm.

We’re more than just a diamond store; we’re a place where you’re always welcome. Our engagement ring and diamond experts are available by phone, email, online chat or private consultation (by appointment only) 7 days a week at our London office.

We are the only diamond retailer to offer a Double-the-Difference Price Guarantee.

All our products are backed by a Lifetime Warranty and Free Extended Returns to 05 August 2013.
