One of the special characteristics of sapphire is the big variety of intense, rainbow colors, such as: blue, violet, orange, yellow and green. Each stone, however, has a different shade and tone. For our Confetti rings we choose subtle nuances in a color theme. “Picking the best stones is a never-ending, fun challenge. Once the stones are set, I am always amazed by how every Confetti ring is not ever the same.”, says Esther (gemologist at Bron).

Elegant but cool is the black variation of sapphire. Like pepper, we use them to spice up our Confetti, Stax, Joy, Sushi, Reflex and Sprite collections.

In addition, sapphire belongs to the corundum family. The minerals’ hardness is 9 (out of 10), making it the second hardest gemstone on the Mohs scale.

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.
