According to relevant data, silver sand with blue and white seed material is worthless. This is because the blue-and-white seed material belongs to an imperfect variety of Hetian jade and jet, and its black is dotted, which affects the appearance. Therefore, the market value of Yinsha blue-and-white seed material is low.

Please note that the collection value and market value are different. Although the blue and white silver sand seed material may not be very valuable in the market, if you personally like this material, it can also be used as your personal collection. In addition, for jewelry and other application scenarios, blue and white seed materials with silver sand can also have certain decorative value.
