瑰宝
guī bǎo · HSK 7
treasure
💎 瑰宝 = 瑰 (rare jade) + 宝 (treasure) = a rare and precious treasure
瑰 means a fine, rare jade or marvel; 宝 is treasure, written as jade 玉 kept safe under a roof 宀. Put together they name a gem or any rare, valuable item. The bǎo sound is the same 宝 found in 宝贝 (baby/treasure).
宝 — roof 宀 + jade 玉 (simplified from 寶)
Originally written 寶, showing a roof 宀 over jade 玉, a jar 缶, and shell 貝 (money) — valuables kept safely at home. The simplified form 宝 keeps just the roof and jade, preserving the core idea of 'treasure.' It now means treasure, precious, or valuable.
