We specialise in supplying high-value premier cut quality diamonds in tailor-made jewellery to suit your needs and budget. Unlike many online retailers, we buy and sell each diamond with expertise and like to meet you to discuss your needs as well as let you choose from a selection of loose diamonds so that each item is tailor-made for you.

Diamond House Jewellery is a direct supplier of the finest quality certified diamonds and luxury diamond jewellery from source in Antwerp at wholesale diamond prices.  8 out of 10 diamonds sold in UK, Europe and US originate from Antwerp.
We have a diamond trade office in London where we meet clients by appointment only.  Our main diamond office and showroom are in the diamond district of Antwerp where we have membership of the Diamond Bourse. It is important to note that we are not a retail shop but a diamond trade office. Shops sell ready-made jewellery - we sell loose diamonds and custom-made jewellery though we do have begun to increase our selection of ready items.
We buy directly from diamond cutters in Antwerp and hand-make to order so that we are able to offer:
•    higher quality diamonds (including premier cut and ideal cut diamonds) that meet your Cut, Carat, Colour and Clarity criteria
•    fancy coloured diamonds, rare and exclusive diamonds.
•    individual handmade designs tailored to suit your particular tastes
•    Crafted by Infinity diamonds

•    competitive prices for high-value diamonds, typically saving up to 40% when compared to many branded designer jewellery shops

•    the biggest selection of diamonds from the largest diamond market place
•    the advantage of Antwerp diamond quality and pricing from the convenience of London
•    the best cut-quality, premier cut diamonds at direct from Antwerp prices combined with individual, tailored designs
All our diamonds (from 0.35 carat upwards) are accompanied by a worldwide accepted diamond grading report (e.g. HRD, GIA, AGS or IGI) and are hand-picked to select only well-cut diamonds as it's the diamond Cut proportions which determine how well a diamond will sparkle.
We specialise in classic and bespoke designs that are not readily found in one place in London or elsewhere in the UK.  We also specialise in diamond solitaires including: round brilliant diamonds and fancy diamond shapes such as: princess cut diamonds, pear shape diamonds, emerald cut diamonds, cushion cut diamonds, asscher diamonds, radiant cut diamonds, oval diamonds, heart shape diamonds, marquise shape diamonds, baguette cut diamonds and more.
Our clients are those who typically want quality, tailor-made pieces at competitive prices.
For people who want all the quality and style of the prestigious designer shops with twice the diamond or around half the price combined with personalised service where each piece is individually tailored.
We also offer more independent guarantees for diamonds than many prestigious designer shops. See what our clients say about us on our “Testimonials” page.
You can meet with us in London or Antwerp to view and select from loose diamonds.
As we have an in-house team of designers, platinum-smiths and goldsmiths – we can design and create any style of jewellery that you like or supply just the loose diamond, as you prefer. Bespoke design and making is our standard and incurs no extra cost as we provide the jewellery-making at cost as an added-value service to our diamond clients.
There are now many online diamond vendors selling certified diamonds and there are also fine designers who tailor-make - we combine both services in one place so that you can get the best quality Antwerp diamonds in tailor-made designs for a direct from Antwerp price as well as local accountability and convenience in the UK.
