Indeed, the so-called strass effect looks like diamond gloss, consequently, sometimes strass-gem is taken for as natural gemstone. Only customers that dont have the ghost of a notion of real diamond can be jockeyed, others – without a chance. Rock crystal does not have props typical for natural gem: durability, high heat conductivity and longevity. The cause for that is that both of gems are of diverse kind and structure. Of course, diamante is much cheaper therefore everyone can afford buying Replica Jacques Lemans London Watches, but in any case it wont be as a real stone at any rate.A very best-selling natural diamond substitution on market is Cubic Zirconia. It is isometric, just like diamond is. This property really makes it look like a 100% natural diamond. But Cubic Zirconia is man-made material that why in order to form crystals and in order to let them continue staying firm at standard temperature stabilizer is essential. As usual calcium oxide or yttrium are used for such stabilizers, but the amount of these elements is determined by producers independently. So, the thing is that these stabilizers stay in the manufactured product. This makes the loose stone to weight much more than natural diamond.

Simulated stone consists of 100% the same constituent as real diamond gemstone – true carbon. Lab grown gemstones do have the characteristics as natural gems: chemical, physical and optical properties. These of the glistering effect, longevity and solidity as natural gems.
