“Whether freshwater, South Sea or Tahitian, at Bron we love all kinds of pearls. Their natural beauty and unique shapes, combined with our precious gemstones and 18 karat gold, create one-of-a-kind jewelry pieces.” Hans Boekhorst, Master Goldsmith at Bron
The sizes of our pearls vary from 8mm to 15mm. They grow, like almost all pearls on today’s market, on oyster farms. There, little pellets of mother of pearl are inserted on the insides of the shells. Due to a natural defense mechanism, mother of pearl is emitted and the pearls start to grow. After a period of one to several years, the oysters are opened and finally pearls can show their extraordinary shapes and color variations.

Mohs hardness: 2.5-3.5

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.
