This week we are focusing on stone types we’ve recently restocked. Some of them are stones we see all the time, like the many jaspers available on the market, while others we are surprised to find again. That’s because each stone type has a product cycle, and there are many reasons why a stone type may disappear from the market.

Here are a few of the most common reasons stone types become unavailable:

1. The material grade drops below Dakota Stones quality standards. We constantly monitor our production quality to make sure it meets our strict standards.

2. The factory runs out of material. In these first two situations, we would need to acquire new material from different locations around the globe.






3. There is a lack of material available on the market. Often a mine digs enough material at one time to sell for years and may not be able to dig more in the near future. Many factors prevent a company from mining more materials, such as the expense to operate machinery, the weather is not conducive to mining, or the government has restrictions on mining (for example, China currently has government restrictions on mining turquoise.)



4. The material is mined out. This does not happen often, but stone types can go extinct. This is more common in rare or unusual stone types that have formed in small regions. This was the case with Gaspeite an eye catching chartreuse green stone discovered while mining copper in Widgiemooltha, Australia. There is still small amounts of rough on the market for those willing to pay, but for the most part it would be considered "mined out" or extinct.

The above scenarios can occur to any stone type during the production cycle and we do our best to meet the challenges and keep your favorite stone types in stock. Occasionally there are factors beyond our control that prevent us from getting stone types again. In those cases, know that we are working hard to bring them back!
