How to determine the crystal
By purchasing a product made of rock crystal, carefully examine it before buying. Inexperienced buyers often difficult to identify a fake. Of course, to be completely confident in buying, crystal should be subjected to diagnostic gemological equipment. But you can use simple visual techniques that will help to accurately determine the authenticity of the object.
Instruction how to determine the crystal
The rock crystal is thicker, you never see the bubbles. This feature can only be glass. It frequently gas bubbles of different sizes.
Explore a subject for the presence of striae. So called inclusions which are cooled line, left current waterglass. Often, they are visible to the naked eye. They can be found when considering the product on the lumen. Most often they resemble fine threads, ribbons and knots with "tails". Sometimes they are almost invisible. To identify such streaks have to use special methods. For example, to examine the subject of the rays of polarized light. Streaks differ from the total weight of the glass of the refractive index, density and color. The crystal structure of rock crystal streaks can not be.
Before buying a crystal product, carefully inspect it. Look at the various crystal defects. This crack may be hazier. Their presence indicates that the stone was created by nature, not by man.
Rock crystal, unlike glass, has a high thermal conductivity. Apply the product to her cheek. Glass heats the object directly. Crystal stone will remain cold for longer. Products with low thermal warmer to the touch than high.
Rock crystal, unlike glass, steel knife is not scratched. If you have a steel knife, try a little scratch the product. Rather, the glass and steel succumb to surface scratches remain. Rhinestone in this procedure will remain in its original form.
If the thickness of the product is the same over its entire area, perform the following experiment. Look through it for every little thing. Glass tends to slightly increase the items. In particular there is a crystal.
Rhinestone can visually bifurcate items. For example, if you put a ball of crystal on the edge of a sheet of paper, then the edge will look like a forked. Glass ball this effect does not.
