Spessartite grenade

“When working with spessartite or mandarine grenade in the atelier, surrounded by all my tools and the darker industrial colors, the gemstone appears to evoke the opposite feeling. It’s clean and carries all the light, as a setting sun. It’s magical!” Rik, Stonesetter at Bron

This orange variety of the grenade family is precious because it’s only found very rarely. In our Bron collection, we claim the spessartite as ‘special’, because we only select bigger sized gems in high quality. These are even less likely to be discovered, which is why they are not always available. The gemstone got its name from a region in Middle Germany, that is called Spessart. There it was brought to light for the first time. 

Colors: light to dark orange

Where to dig for it: Nigeria and Tanzania

Mohs hardness: 7-7.5


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.
