tru diamonds: what to know before you buy
Understanding what you are buying
Tru-Diamonds jewellery uses lab-grown simulated diamonds set in a sterling silver core, with a thin plating of 18 carat gold or platinum over the top. This is a fashion-jewellery construction rather than solid precious metal, so it is worth matching your expectations to that. The stones are described as non-mined, which is the main reason the prices sit far below mined diamond rings.
Checking carat sizes and stone details
The store lists carat sizes for each piece, and it notes that items with several stones show a total weight, marked as t.w. Read that figure carefully when comparing a multi-stone trilogy or eternity design with a single-stone ring, because the same carat number can look very different depending on the setting. A size guide for the stones is also provided on the site.
Choosing between sizes and metal finishes
Most products are offered in two metal types, so pick the finish you actually wear. If you are buying a ring, request a ring sizer or use the online sizing guide before ordering, since returns for the wrong size need to be arranged in advance.
Planning your purchase around returns and timing
The 30-day money-back guarantee gives you time to try a piece at home, but returns must be logged online first and the item must be unworn and in its original packaging. Pieces bought on sale or at a discount are refunded as store credit unless you request cash when logging the return. For UK orders, in-stock items are listed as arriving within 2 to 3 business days, while out-of-stock items may take 14 to 21 days because each piece is hand finished.
Questions about tru diamonds
Are there any tru diamonds discount codes?
We currently list 7 discount codes. Check each offer's terms, country and expiry date before using it. The retailer confirms eligibility at checkout.
Where can I check tru diamonds's refund policy?
Read the retailer's current policy before buying. Eligibility can depend on the product, its condition and whether it has been used or activated. Delivery and returns policy
Are Tru-Diamonds pieces solid gold or platinum?
No. The mountings have a solid sterling silver core with a thin plating of 18 carat gold or .950 platinum over the top, so they are not solid precious metal.
How long does UK delivery take?
The store says in-stock jewellery usually arrives within 2 to 3 business days, while items not in stock may take 14 to 21 days because each piece is hand finished.
Who handles my order?
You complete your purchase with the retailer. For order changes, delivery questions or a refund, contact the seller shown on your order confirmation. Vouchernaut publishes shopping guides and offers; we don't process your purchase.
