The most expensive metal in the world
Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.

Handmade crystal glass as a work of art
In order for the colored crystal to open in all its beauty and sparkle with every face natural light is required. Handmade crystal glass has specific tactile and aesthetic properties - it is pleasant to touch, it seems to radiate heat. To appreciate the quality and beauty of such things, of course, it is not enough to look at the picture.
Foam
