Cubic Zirconia & Gems PRODUCT CATALOGUE CUBIC ZIRCONIA & GEMS PRECIOSA COMPONENTS PRODUCT CATALOGUE CUBIC ZIRCONIA & GEMS Preciosa® Cubic Zirconia & Gems are cut exclusively from CUBIC synthetic crystals of the highest quality controlled by modern spectral ZIRCONIA methods. We can thus guarantee the maximum optical purity of the final product. Using extremely precise cutting and polishing & GEMS machines, we are able to cut round stones from cubic zirconia in sizes ranging from 0.5 to 8.0 mm. Our offer includes 29 colours and a variety of stone shapes. Preciosa® also supplies round stones cut from other materials, such as synthetic spinel, synthetic corundum, emerald green and black nanocrystal. The outstanding feature of these exclusive synthetic materials is their exceptional stability which is important for all jewellery setting techniques, including the wax casting. The Star Effect GEMS This optical phenomenon appears inside each Preciosa® & Cubic Zirconia Stone, testifying to the superior quality of the stone and its absolutely precise cut.

  • Colourless Gemstones

Another man-made gemstone called synthetic Moissanite was introduced as a diamond simulant in the late 1990s. Although TED A synthetic Moissanite tests positive on a FFILI A diamond tester, it is easily distinguished from diamond by a property called double refraction, detected using a 10x loupe.

It was decided to carry out a radiographic version of ‘MythBusters’. The study involved the investigation of the urban myth about a female radiographer who accidentally x-rayed her hand, only to discover that her diamond engagement ring was a fake. To prove or disprove the legend, a number of natural diamonds and cubic zirconia crystals were radiographed. Sure enough, there was a definite and consistent difference between the resultant images. The study confirmed part of the myth that radiography can differentiate between a diamond and a cubic zirconia fake diamond. Keywords: cubic zirconia, diamond Introduction on radiology.4 In his book Something about x-rays for everybody, It is sometimes difficult to separate truth from urban legend, there is a picture which is possibly the first published radiograph but when it comes to radiography, x-rays do not lie, although they of a diamond ring. do need to be interpreted properly.

The spectrum of the strong luminescing feature also has characteristics of Neodymium (Nd3+) and has a multiexponential decay behaviour. Real-time detection of cubic zirconia mounted in diamond jewellery containing very small stones ( 0.01 ct) is made possible, ≤ where observation by loupe is more challenging or other conventional techniques impractical and or slow to implement. The near infrared observed can be excited using a low-cost and eye/skin safe-visible green LED light source and the time-gated imaging of the luminescence using a machine vision monochrome camera. The use of near infrared, time-gated detection in combination with other verification instruments increases the robustness of screening diamond parcels.
