Radiance® Diamond Simulant

Now you can have the look of collector quality diamonds at a fraction of the price. Guaranteed.

The Radiance® diamond simulant is exceptionally beautiful, amazingly durable and surprisingly affordable.

Radiance® diamond simulants are created using a coating of millions of sp3 bonded amorphous Diamond Like Carbon (DLC) crystals aligned together. These actual "diamond" crystals are applied to a highest quality cubic zirconia available. The result gives Radiance® a beauty that exceeds even natural diamonds and an amazingly durable, protective outer layer that is both brilliant, affordable and much more durable than standard cubic zirconia or other imitation diamonds.

Radiance® diamond simulants have the look of the finest collector quality natural diamonds but at a fraction of the cost. Each Radiance® diamond is precisely cut to ideal specifications for maximum brilliance, has flawless clarity and is virtually colorless. The result is the most brilliant, bright, crystal clear diamond alternative available.


Radiance® diamond simulants are colorless, in the D-E-F color range




Radiance® diamond simulants are virtually flawless




All Radiance® diamond simulants are ideally cut to exact diamond industry proportions for maximize brilliance



A lifetime of beauty, guaranteed!

All Radiance® diamond simulants come with a limited lifetime guarantee against scratching, scuffing, chipping, brilliance and even loss. Should anything happen to your Radiance® diamond, simply return it to Joseph Schubach Jewelers to have it replaced for a nominal resetting fee.

Modern nano-technology makes Radiance® diamond simulants beautiful, brilliant and affordable

The most common diamond simulant is cubic zirconia – which dates back to its discovery in 1937, when two German mineralogists discovered the cubic form of zirconium oxide. Soviet scientists learned how to “grow” this mineral in a laboratory in the 1970s, and cubic zirconia became the most widely sold diamond simulant (imitation diamond) in jewelry. Premium grade rough combined with fine cutting provides a fine looking imitation to a diamond but there are noticeable differences namely the slightly lower brilliance than a diamond as well as the "white table flash", "glassy look" and "dead spots when viewed from an angle".

Do not confuse a Radiance® diamond simulant with plain cubic zirconia sold under various names such as Diamond Nexus Labs, Brilliante, Russian Brilliants, Diamonique, Van Graff, or Zirconite.

Radiance® is non porous so lotions, oils soaps, etc. do not stick to the gemstone as easily, remain brilliant and do not cloud like most simulated diamonds.

It is virtually impossible to visually distinguish Radiance® from an internally flawless super-fine natural diamond. The amazing look of Radiance® is attributed to the amorphous Diamond Like Carbon coating that renders it with exceptional sparkle and beauty, comparable to the finest natural diamonds. The only way to positively identify Radiance® is by its weight, hardness and chemical component using grading laboratory equipment. Radiance® is precisely cut to ideal proportions with ideal symmetry, ideal proportions, and ideal polish, as well as thin polished girdles. Until now the only popular diamond alternatives have been Cubic Zirconia, white sapphire and Moissanite.

As with any gemstone, laboratory-created diamond simulants such as Radiance® are evaluated on the basis of the four Cs: carat, cut, clarity and color. The hardness level of a man-made Radiance® is 8.5, which is harder than many gemstones. Caring for these radiant stones is easy; just clean it as you would clean a regular diamond! You will find a beautiful selection of Radiance® diamond simulants for sale on our website - at incredibly affordable prices! Whether you are seeking the classic round shape to create ring or necklace settings, or are searching for a unique shape such as a heart, oval, octagon, square, marquise, pear or star, we can meet your needs.

Technical Data

The DLC process is very 'green'. It is a vacuum process using small quantities of safe gasses and so are environmentally benign.

Carbon is the primary element in Diamond Like Carbon (DLC), the same as diamond.

DLC exists in seven different forms of amorphous carbon materials that display some of the unique properties of diamond

DLC coatings are commonly used in the aerospace industry, manufacturing, biomedical, performance racing, food service and other industries.

DLC coatings can be made that at the same time are amorphous, flexible, and yet purely sp3 bonded "diamond"

DLC films are generally amorphous, having no overall crystal structure as do graphite and diamond.

DLC contain significant amounts of sp3 hybridized carbon atoms.

DLC provide some of the properties of diamond to surfaces

DLC coatings increase the resistance against abrasive wear; changing the lifetime of some materials from one week to 85 years

There are many ways to deposit DLC films. The most common methods involve a vacuum chamber and a power supply. Common methos are Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD) and Ion Beam Assisted Deposition (IBAD).

Don't take our word for it. Read what the experts are saying about the benefits of DLC coatings at Wikipedia and in other scholarly journals.
