💎 如何识别真正的锡兰蓝宝石：专家购买指南
🔎 介绍：蓝色闪耀背后的真相
一颗 锡兰蓝宝石 是世界上最受推崇的宝石之一，但美丽背后也有仿制品。如果您打算投资蓝宝石，了解如何 识别真正的锡兰蓝宝石 至关重要。
这本专家指南帮助您识别真实性的迹象，避免宝石市场中的常见陷阱。
👁️ 1. 视觉与宝石学的真实性迹象
虽然只有专业检测能确认蓝宝石的产地，但有视觉线索：
| 特征 | 购买要点 |
|---|---|
| 颜色 | 明亮、鲜艳的中等皇家蓝，饱和度良好 |
| 净度 | 通常肉眼干净，带有天然内含物 |
| 切工 | 斯里兰卡蓝宝石通常由人工精确切割 |
| 包含内容 | 细小的羽状或指纹状内含物（天然标志） |
⚠️ 注意：
-
看起来过于完美或颜色过深的宝石
-
“透窗效应”（宝石中心无色彩反射的区域）
📜 2. 为什么证书很重要
务必索取来自信誉良好实验室的宝石证书。对于锡兰蓝宝石，这证实了：
-
产地（斯里兰卡）
-
所做的处理（加热、扩散等）
-
天然与合成状态
-
精确的克拉重量、净度和切工
🔍 推荐实验室：
-
GIA（美国宝石学院）
-
IGI（国际宝石学院）
-
GRS，Lotus Gemology，或SSEF用于高级宝石
- 斯里兰卡其他知名宝石实验室，Guild，GIC，EGL
🧪 3. 了解常见处理方法
大多数蓝宝石经过加热处理以增强净度和颜色——但并非所有处理都相同。
| 处理类型 | 是否可接受？ | 笔记 |
|---|---|---|
| 加热处理 | ✅ 是 | 传统且永久 |
| 扩散处理 | ⚠️ 否 | 表面人工着色 |
| 裂缝填充 | ❌ 避免 | 降低价值；缩短宝石寿命 |
| 合成蓝宝石 | ❌ 避免 | 实验室合成，无天然价值 |
💡 提示：请索取明确标注“天然，仅加热处理”或“未加热”的报告。
