I bought two pieces of Huang Longyu when I traveled to Yunnan. Is it collectible?

Huang Longyu, also known as the Dragon and Yellowstone. High-quality gem-grade Huang Longyu is mainly produced in Xiaoheishan Nature Reserve in Longling County, Baoshan City, Yunnan Province and the surrounding Supa River Basin. Reserves are scarce. Huanglongyu, with fine stone, golden color and huge block shape, is even better. At the beginning of 2004, the good mountain materials in the market only cost a few yuan per kilogram, but now it has risen to several thousand yuan or even ten thousand yuan per kilogram. Because of the scarcity of resources, good seed materials, turf materials, mountain streams and grass flowers are hard to find, and the prices are in rapid and sustained growth. The value of Huang Longyu mainly depends on color, structure (texture), transparency, cleanliness, luster, cracking, technology and so on. Your color is not bright, but the texture is delicate and shiny. Although the quality is not very good, considering the rising prices in Huang Longyu, it is also worth collecting.
