Diamonds Factory Active Deals, Sales & Codes in August, 2026

Headquartered in London’s historic Hatton Garden, Diamonds Factory operates as the online retail division of Neve Jewels Group. Founded in 2009 by the Jain family, the brand draws on four generations of diamond manufacturing expertise to supply buyers directly. By bypassing traditional high street middlemen, they offer significant savings on fine jewellery without compromising on craftsmanship or certification.

The catalogue covers every major milestone, from engagement and wedding rings to eternity bands, pendants, and bracelets. Prices are surprisingly accessible; you can pick up silver or lower-carat gold gifts from under £50, while serious investment pieces scale up through various carat weights and clarity grades. Because every item is made to order, customers can customise metals, settings, and stone specifications to suit exact preferences.

Beyond the initial price drop, the retailer builds serious trust into the purchase. Every piece arrives with a lifetime warranty and a 30-day free ring resizing service, which takes the anxiety out of guessing a partner’s exact finger size. They also offer a hassle-free 30-day return window and free insured delivery across the UK and worldwide, ensuring the buying process feels as secure as a physical boutique visit.

Pairing these direct-to-consumer margins with the discount codes listed below makes securing a luxury piece significantly more affordable.

When is the best time to buy an engagement ring? We generally see the steepest discounts land just after the festive season and during late-summer clearance events. Diamonds Factory frequently runs flash sales offering up to 55% off last chance orders during these windows. If you are working to a strict timeline, however, their made-to-order model means you should factor in a few weeks for crafting and hallmarking regardless of the season.

Should I buy a pre-set ring or use the customisation tools? Pre-set designs are usually ready to dispatch faster and often feature in the automatic RRP promotions. But if you want a specific clarity grade or a unique metal combination, the site’s detailed filters let you build a ring from scratch. We find that starting with a slightly lower colour grade but prioritising an excellent cut yields the most sparkle for your budget, a trick that works exceptionally well on their configurator.

How do I ensure the ring fits perfectly? Guessing a partner’s ring size is notoriously stressful, but the retailer completely removes the risk with their 30-day free resizing policy. If the proposal goes well but the ring slips off, you simply send it back for a swift adjustment at no extra cost. This safety net makes buying a surprise proposal piece far less daunting than shopping on the high street.

Are lab-grown diamonds worth considering over natural stones? Absolutely. The retailer offers an extensive lab-grown selection that is chemically identical to mined diamonds but typically costs significantly less. We often recommend this route if you want a visibly larger carat weight on a modest budget. The money you save on the stone can then be redirected towards a more intricate precious metal setting or a matching wedding band.
