What is Xiuyan Jade?
Xiuyan Jade, named after its origin in Xiuyan County (Liaoning Province, China), is one of "China's Four Great Jades", alongside Hetian Jade, Lantian Jade, and Dushan Jade. Renowned for its soft luster and diverse hues, it holds a revered place in Chinese history and gemstone artistry.

Types & Composition
Xiuyan Jade is categorized into two primary types based on mineral composition:  
1. Serpentine Jade: The most common variety, composed mainly of serpentine minerals. It exhibits waxy to glassy luster, with colors ranging from green, yellow, and white to translucent green grape milk foam patterns - a mix of green serpentine and milky-white tremolite.  
2. Xiuyan Nephrite: A rarer form rich in tremolite, similar to Hetian Jade, prized for its toughness and fine texture.

Historical Significance
- Dating back to Neolithic times (e.g., Hongshan Culture, 4700–2900 BCE), Xiuyan Jade was carved into ritual objects, ornaments, and tools.  
- Imperial artisans used it for intricate sculptures, jewelry, and decorative items, symbolizing status and spiritual connection.  

Unique Properties
- Color Spectrum: From pale celadon to deep emerald, often with swirling patterns or translucent layers.  
- Hardness: 4.5–6 on the Mohs scale (softer than nephrite but ideal for detailed carving).  
- Cultural Symbolism: Believed to promote harmony, purify energy, and attract prosperity in Chinese metaphysics.  

Modern Applications
Today, Xiuyan Jade is widely used in:  
- Jewelry: Beaded bracelets, pendants, and rings.  
- Carvings: Figurines, vases, and auspicious symbols.  
- Spiritual Tools: Meditation stones and Feng Shui items.

Care Tips
- Avoid harsh chemicals and prolonged sunlight to preserve its color.  
- Clean gently with a soft cloth and mild soap.
