Amber collector’s item

According to tradition, amber was the most sought-after product in ancient times. Even Odysseus gave his wife Penelope a golden necklace set with amber. The Greek trade route ran across the Black Sea along the Dniester, and the Etruscans traveled along the Rhine route. In Roman times, the city of L’Aquila was a center for the processing and distribution of amber.

Moissanites are almost as hard as lab-grown diamonds, with a value of 9.25 on the Mohs hardness scale. This makes them very robust and suitable for everyday use. Moissanites have a higher refractive index, which gives them a different brilliance than a lab-grown diamond.

Silicate minerals are rock-forming minerals that consist of silicate groups. They are the largest and most important class of minerals and make up around 90 percent of the earth’s crust. In mineralogy, silica (silicon dioxide, SiO 2 ) is usually considered a silicate mineral and not an oxide mineral.
