Tru-Gold™ and Tru-Platinum™ are proprietary terms for Tru-Diamonds™ jewelry to describe settings which have 4 microns of 18ct. Gold or. 950 Platinum fused over a solid core of sterling silver. This results in a far more luxurious product than vermeil which is plated with only 2.5 microns of 10ct. gold. Our settings look like solid 18 carat Gold or .950 Platinum but cost a fraction of the price. Whilst not intended for a lifetime of everyday wear Tru-Gold™ and Tru-Platinum™ jewelry will retain its luxurious appearance for many years if properly cared for.
