Yes, chocolate sapphires. I love them -well, I love sapphires, any color!- 
Set in a classic claw style this faceted hexagons show best their beauty in the sunlight where their chatoyant light emerges the most.
In sterling oxidized super rustic brutalist style, long but not excessive, are a show and a wow in their unusual look.
They measure approx. total 76mm -long-
The card, ruler and coin hopefully give an idea of their real size.
