The name aventurine is derived from the Italian sentence “a ventura”, which refers to the shimmering inclusions that “with fortune” can be found in it. The ancient Greeks believed that the gemstone imparts courage and optimism. For us, the fresh green shades of aventurine remind of a park that blooms in spring. Together with amethyst, the stone is part of our SS 2018 ‘Walk in the Park’ color theme.

The Mohs hardness scale

The Mohs hardness scale describes a scale from 1 to 10, which indicates the relative hardness of a mineral. Diamond is the hardest substance in the world and is therefore rated with the highest hardness grade of 10. To further illustrate the Moh's hardness it helps to imagine that a moonstone
(hardness 6) is about as hard as the blade of a kitchen knife. A fingernail would only measure a grade of 2-2.5 on the scale.

At Bron, the hardness plays a minor role. Our overriding selection criteria are color and the ‘liveliness’ of a gemstone.
