Changbai jade, originating from Changbai County in Jilin Province, is a unique and highly valued stone. Known for its fine, dense texture, it possesses a warm and clean feel, being firm yet not rigid, light but not slippery, making it ideal for carving. Its luster is excellent, with most varieties being translucent or semi-transparent, except for a few that are fully transparent. The color palette includes green, yellow, gray-brown, purple-red, and gray, offering a wide range of aesthetic possibilities. The patterns on the stone are striking, featuring crepe-like textures, moiré effects, curling lines, rhyolite-like structures, and smooth, flowing designs, all contributing to its natural and elegant appearance.
Changbaiyu, a significant mineral resource in Changbai Mountain, is primarily found in Malugou Village within the Changbai Mountain Korean Autonomous County. This gemstone has been forming for over 130 million years, dating back to the Late Jurassic period. It was formed through volcanic activity, with pyroclastic materials depositing over time. Its main component is pyrophyllite, which gives it a soft yet durable structure, making it popular among artisans and collectors alike.
Yela stone, another notable material from the region, is celebrated for its "fat" texture and vibrant colors. It is soft and malleable, making it an excellent choice for carving and seal-making. In China, it is often referred to as "stamp stone" due to its popularity in traditional calligraphy and seal engraving. Among its many qualities, Yela stone is prized for its transparency, earning it the nickname "frozen stone." This volcanic rock is porous and lightweight, with a loose structure that allows for good air permeability. Rich in essential elements such as silicon, aluminum, iron, potassium, sodium, calcium, magnesium, sulfur, manganese, phosphorus, and strontium, it exhibits a diverse range of colors, including black, dark green, and brick red. Its unique composition and physical properties make it a sought-after material in both artistic and practical applications.
