Natural Crystal Identification
Look closely before deciding
Natural inclusions, growth patterns and color zoning can be informative, but appearance alone is not always enough. For high-value pieces, request a report from a qualified gemological laboratory.
判断之前先仔细观察
天然包裹体、生长纹与色带能够提供线索，但仅凭外观并不总能得出结论。高价值晶石应向专业宝石检测机构申请证书。
