The Majestic – Night Sky Limited edition belongs to the elegant Biatec Majestic Collection and features a unique dial from natural stone (quartz) called blue Aventurine. Since this stone is fragile at the thickness of the dial, only the best factories in the world are capable to apply at this stone indexes by feets. To finish one complete dial means that the 6-9 dials were broken / wasted. Every dial is unique by its structure. The blue Aventurine combines the elements of Wind and Water in a gentle stone that resonates from the mind to the heart, working calmly, rationally, and steadily. It enhances the masculine energy in both males and females, and is a stone of self-discipline and inner strength, assisting one in making clear decisions and sticking by them. It promotes taking full responsibility for one’s life, relationships and experiences, while lending the support needed to empower change when the current reality isn’t working.

Painted by hand

The Night Sky limited edition SILVER coin was painted by hand in one of the oldest mints in Europe (the mint of Mincovňa Kremnica in Slovakia which has more than 700 years of uninterrupted history). So every coin is a piece unique as much as the aventurine dial.

As unique as you are! The name aventurine derives from the Italian "a ventura" meaning "by chance". This is an allusion to the lucky discovery of aventurine glass or goldstone at some point in the 18th century. One story runs that this kind of glass was originally made accidentally at Murano by a workman, who let some copper filings fall into the molten “metal,” whence the product was called avventurino. From the Murano glass the name passed to the mineral, which displayed a rather similar appearance.
