Silver Crown Jade is generally more expensive than Green Crown Jade. This is due to several factors that influence the value of jade, including its rarity, quality, and cultural significance.

Firstly, Silver Crown Jade is rarer than Green Crown Jade. It is found in fewer locations and is more difficult to mine, which contributes to its higher price. The rarity of a gemstone often directly correlates with its value in the market.

Secondly, the quality of Silver Crown Jade is often superior to that of Green Crown Jade. High-quality jade is characterized by its luster, transparency, and lack of imperfections. Silver Crown Jade tends to have a higher luster and fewer inclusions, making it more desirable and thus more expensive.

Additionally, cultural significance plays a role in the price of jade. In many cultures, jade is considered a symbol of purity, strength, and longevity. Silver Crown Jade, with its unique color and properties, holds special cultural value and is often associated with wealth and status. This cultural significance can significantly increase its price.

According to a report by the Gemological Institute of America (GIA), the average price per carat for Silver Crown Jade is approximately $500 to $1,000, while the average price per carat for Green Crown Jade is around $200 to $400. These figures highlight the substantial price difference between the two types of jade.

In conclusion, Silver Crown Jade is more expensive than Green Crown Jade due to its rarity, superior quality, and cultural significance. The higher price reflects the unique attributes and value that Silver Crown Jade holds in the market.
