Diamond Rocks voucher codes apply at a Hatton Garden jeweller offering over 5,000 pieces, with free insured UK delivery by Royal Mail Special Delivery. Orders over £2000 to other worldwide countries ship free, the delivery page names 30 day returns, and PayPal is accepted. The terms and conditions of SK Partnership t/a Diamond Rocks are binding.

Quick answers

How do I use a Diamond Rocks voucher code?

Copy the code from this page, add your jewellery to the basket on diamondrocks.co.uk, enter the code in the code box at checkout and check that the total has gone down before you place your order.
