Nanhong Agate AI Identification
南红玛瑙是中国特有的红色玉石品种，主要产自四川凉山和云南保山。南红以其鲜艳浓郁的红色和温润的质地受到收藏者追捧。按颜色可分为锦红、柿子红、樱桃红、玫瑰红、冰飘等品种，其中满色满肉的锦红最为珍贵。
颜色品种：锦红>柿子红>樱桃红>玫瑰红，满色满肉最佳
注胶检测：观察是否有胶感、气泡或不自然的透明区域
裂纹评估：南红天然多裂，但裂纹大小和位置影响价值
产地特征：凉山料色彩丰富，保山料质地细腻但多裂
常见南红仿品包括：红碧石（与南红外观相似但质地粗糙）、染色玛瑙、烧色玛瑙、人造玻璃、合成材料等。注胶南红虽然材质是真南红，但经过填充处理，价值大打折扣。
AI可以识别南红的颜色品种（锦红、柿子红、樱桃红等）、检测明显的注胶痕迹、区分南红与常见仿品。对于细微的注胶和产地判断，建议搭配实物鉴定。
Nanhong agate is a uniquely Chinese red jade variety, primarily sourced from Liangshan (Sichuan) and Baoshan (Yunnan). Prized for its vivid red color and warm texture, varieties include brocade red, persimmon red, cherry red, rose red, and ice floating. Full-color brocade red is the most precious.
Color Varieties: Brocade red > Persimmon red > Cherry red > Rose red; full color and full flesh is best
Glue Injection Detection: Check for glue-like feel, bubbles, or unnatural transparent areas
Crack Assessment: Nanhong naturally has many cracks, but size and location affect value
Origin Features: Liangshan has rich colors; Baoshan has fine texture but more cracks
Common Nanhong imitations include: red jasper (similar appearance but coarser texture), dyed agate, heat-treated agate, artificial glass, and synthetic materials. Glue-injected Nanhong, while genuine material, has been filled and is worth significantly less.
AI can identify Nanhong color varieties, detect obvious glue injection marks, and distinguish Nanhong from common imitations. For subtle glue injection and origin determination, physical examination is recommended.
