Laboratory created Tru-Diamonds™ are the world’s best-simulated diamonds and are widely recognised as the most authentic, affordable and ethical alternative to expensive, environmentally damaging mined diamonds. To the naked eye - even of a professional jeweller - these amazing diamond simulants are practically indistinguishable from top-grade mined diamonds, only their molecular make-up is different. They look, feel and wear just like fine mined or synthetic diamonds but cost a small fraction of the price. Created in state-of-the-art facilities Tru-Diamonds™ are far kinder to the environment than mined diamonds, where up to 250 tons of earth must be blasted and excavated to find just one carat of gem-quality diamond. What’s more, with Tru-Diamonds™, you can be sure they’re not blood diamonds because we know where and how each of our gems is created and cut.

Our popular Tru-Diamonds™ Boutique on 18 Brook Street, London, England, in the heart of one of the world’s most prestigious shopping precincts, is closed due to redevelopment and we are presently looking for another suitable location but our online store is always open for our burgeoning family of customers around the globe. Online we have a wide range of styles for every taste and budget and feature exciting promotions and discounts. Our 30-Day Money-Back Trial ensures you’ll love showing off your Tru-Diamonds™ jewellery or get your money back whilst our Lifetime Gemstone Guarantee covers your gem and our Lifetime Replacement Warranty means you can replace your piece with new if it becomes worn or jaded although, if properly cared for, it should last a lifetime.

The most important difference between mined diamonds and laboratory-created Tru-Diamonds™ is the impact each has on the environment. Consider the massive damage that diamond mining does to the environment with up to 250 tons of earth blasted and excavated in order to find just one carat of a fine gem diamond. What’s more, mined diamonds have been used to finance conflict and exploit child labour causing misery for millions in their wake. No matter what assurances a jeweller gives you, it is impossible to know, with certainty, that your stone is not a Blood Diamond. Tru-Diamonds™, on the other hand, are created under controlled conditions that are kind to the environment and leave no carbon footprint. This means you can be absolutely certain that they are NOT blood diamonds. The other important difference lies in their chemical composition: Mined Diamonds are pure carbon where as Tru-Diamonds™ are created from a combination of rare minerals. A survey of British women showed that the overwhelming majority did not know or care about the chemical composition of their gems so long as they looked authentic, lasted a lifetime and stood up to the same wear and tear.

Tru-Diamonds™ are diamond-like, zircon-based gems, formed by a scientific process that heats rare minerals to over 5,000 degrees Fahrenheit, under strictly controlled conditions. This results in a diamond-like, crystalline cubic form of zirconium dioxide (ZrO2) which, when synthesised, is super hard and optically flawless. It should not be confused with zirconium silicate (ZrSiO4), sometimes erroneously called "cubic zirconium". The internationally registered trademark, Tru-Diamonds™, guarantees you the very finest gems available from this process. So strict is the quality control procedure for selecting Tru-Diamonds™ that every one of our gems comes with a lifetime guarantee that even the finest natural diamonds, costing a fortune, cannot match.

Like mined diamonds, Tru-Diamonds™ gems will last a lifetime and beyond if properly cared for. This simply means cleaning your jewellery regularly and keeping it away from creams, lotions and harmful chemicals. For more details, see Jewellery Care & Cleaning. Tru-Diamonds™ are exceptionally hard and durable. But like their mined counterparts it is possible, although very rare, that they get chipped or damaged. The huge advantage with Tru-Diamonds™ over mined diamonds is that in the unlikely event your gem should get damaged or discoloured, we give you a replacement gem free of charge.

Although Moissanite is a naturally occurring gemstone, like Tru-Diamonds™ all the Moissanite on the market today is created. Pure white Moissanite is rare as most stones tend to have a green, yellow or brown tint whereas all Tru-Diamonds™ gems are ice-white in colour. Also, most Moissanite stones have minor internal flaws or inclusions and some jewellers say that the internal facets can appear blurry when examined closely due to the crystal structure which alters the light wavelengths unevenly within the stone. Tru-Diamonds™ are more stable, from an optical point of view, with ultra-clean facet lines from the top of the gem.

Gold Clad and Platinum Clad Settings are made by fusing a generous layer of 4 microns of 18-carat Gold or .950 Platinum onto a solid core of sterling silver. This results in a far more luxurious product than vermeil which is plated with a maximum of only 2.5-microns of 10-carat gold. Jewellery set in our proprietary “Clad” finishes looks like expensive diamond jewellery but is yours for a fraction of the price. If properly cared for, these settings can stand up to many years of normal wear and are ideal for the jewellery you don’t wear day-in and day-out over a long period of time. Most Tru-Diamonds™ rings are also available in solid 9ct. Yellow or White Gold which makes them ideal as engagement rings or rings that will be worn day-in and day-out over many years. They are somewhat more expensive than the “Clad” versions but still cost only a fraction of the price of their mined diamond counterparts.
