Sard Value and Price
Is Sard Rare?
No, Sard is not particularly rare and can be found in most gemstone markets. However, a good quality Sard stone will usually cost more than other gemstones.
Is Sard Valuable? (price per carat)
This stone isn’t generally sold on its own. Sard stones with streaks of Onyx mixed in are usually sold under the name Sardonyx. The Price Per Carat for this combination is around $14.99.
Not all stones are created equal. There are only three main factors to pay attention to when determining the price of a stone. They are color, cut, and clarity.
- Color: The color of a stone is the most visible, which will impact the price. These stones are usually brown or reddish-brown, which means they will have a higher value than other colors. For Sard, color is a significant factor because it affects how much light passes through the stone. The darker sard stones tend to be more valuable than lighter colors due to this reason.
- Cut: The cut impacts the price of a gemstone. A stone cut delicately with many surfaces will have a higher value than one that hasn’t been cut at all. This makes sard stones more expensive per carat than gemstone combinations with smaller, granular pieces with a generally smooth exterior.
- Clarity: Good clarity is vital. A cloudy stone or one with impurities will have a lower value than one with fewer defects. Although Sard stones are usually not very clear, that doesn’t equate two stones that have different levels of clarity. A clearer, more translucent stone will always be better than a cloudier one because if any blemishes or inclusions are present, they will decrease its value.
