Money saving tips
- Join the DF Club newsletter: Registering your email address on the Diamonds Factory website signs you up for the DF Club, which provides an introductory discount code for your first purchase alongside early notifications for seasonal sales.
- Check the Spend and Save promotions: The retailer frequently runs tiered basket promotions (such as £100 off orders over £1,000 or 10% off when spending £1,500). If your order is close to a qualifying threshold, adjusting stone specifications or metal grades can unlock a lower overall net price.
- Use the Price Match Guarantee: Diamonds Factory offers a price match guarantee on comparable certified diamonds and settings. If you find a diamond of identical cut, colour, clarity, carat weight, and certification from a UK competitor, you can submit the quote before purchasing to request a match.
- Take advantage of free resizing: Standard rings purchased from Diamonds Factory include one complimentary ring resizing within the first 30 days of receipt, eliminating the extra cost of local adjustments if the initial size is incorrect.
- Consider lab-grown diamond alternatives: Most ring designs on the website allow you to choose between natural and lab-grown stones. Lab-grown diamonds carry identical physical and chemical properties but cost significantly less per carat, allowing for substantial savings on larger carat weights.
Delivery and returns
Delivery options Standard UK delivery is free on all orders via Royal Mail Special Delivery or tracked courier services. Because most pieces are custom-made or made-to-order, manufacturing and dispatch times typically range between one and three weeks, though a selection of "ready-to-ship" items is available for next-day dispatch. Deliveries are fully insured during transit and arrive in discreet, unbranded outer packaging to conceal the contents and sender name.
Returns policy Diamonds Factory operates a 30-day return policy for standard, unworn items with original security tags and certificates intact. Customers can return items by post using a tracked, insured service or drop them off for free at any physical showroom by appointment. Bespoke designs, engraved items, and custom-modified pieces are non-refundable. All standard jewellery includes a lifetime manufacturing guarantee covering structural and craftsmanship defects.
