Distinction Between Carnelian and Sard
The names carnelian and sard are often used interchangeably, but they can also be used to describe distinct subvarieties. The general differences are as follows:
| Carnelian | Sard | |
|---|---|---|
| Color | Lighter, with shades ranging from orange to reddish-brown. | Darker, with shades ranging from a deep reddish-brown to almost black. |
| Hardness | Softer | Harder and tougher. |
| Fracture | Uneven, splintery and conchoidal | Like carnelian, but duller and more hackly (having the appearance of something that has been hacked, i.e. jagged). |
All of these properties vary across a continuum, and so the boundary between carnelian and sard is inevitably blurred.
