Hetian Biyu refers to green nephrite from the broader Hetian/Hotan region of Xinjiang, China. Valued for its fine, compact texture and soft, oily luster, Hetian green nephrite is a durable, understated gemstone that wears beautifully in everyday jewelry—especially bracelets and pendants.
What Is Hetian Biyu (Green Nephrite)?
Mineral species: Nephrite (actinolite–tremolite series), a calcium–magnesium silicate.
Structure & feel: Interlocking fibrous crystals create excellent toughness (resistance to breakage) and a smooth, “greasy/oily” luster when polished.
Hardness: ~6–6.5 on the Mohs scale (hard enough for daily wear).
Appearance: Typically medium to deep green, from “spinach” tones to deeper greens. Translucency ranges from opaque to semi-translucent; fine, dense textures tend to show a soft glow at the edges when backlit.
Origin label: “Hetian/Hotan” is a commercial/geo-cultural origin term for Xinjiang nephrite. Green nephrite is mined in several Xinjiang localities; similar-looking green nephrite is also found in places like British Columbia (Canada) and Siberia (Russia), but only Xinjiang material should be described as Hetian.
Key Features Buyers Notice
Texture (grain size): Fine, compact textures feel smooth and look even under magnification.
Luster: After polishing, quality pieces show a mellow, oily sheen rather than a glassy sparkle.
Color uniformity: Desirable stones have even color without obvious blotches; natural stones may show subtle, cloud-like variations.
Translucency: Semi-translucent edges (when held to light) often indicate finer material.
Rarity & Market Notes
High-quality Hetian green nephrite with fine texture, clean surface, and even, saturated green is limited compared to lower grades. Because demand is strong for uniform “spinach” greens, bracelets and larger beads of consistently good color/texture command premium prices. Surface imperfections (pits, dark mineral spots) are common in natural material and help distinguish it from imitations.
Care & Maintenance
Daily wear friendly: Excellent toughness makes nephrite ideal for bracelets.
Cleaning: Use lukewarm water and a soft cloth; mild soap if needed. Avoid ultrasonic/steam and abrasive cleaners.
Chemicals & heat: Keep away from strong acids/alkalis, perfumes, and prolonged high heat.
Storage: Separate pouch or compartment to prevent scuffs from harder gems.
Why Choose Hetian Green Nephrite?
Durable & comfortable: Toughness + smooth polish = perfect for everyday pieces.
Understated elegance: A soft, refined glow that pairs well with gold or silver.
Timeless value: Classic material with consistent demand, especially in well-matched bead bracelets and clean cabochons.
