標本 - ブルーサファイア天然塊（ブラジル産）

The crystal structure on my chunk is incredibly well-defined, with sharp edges that catch the light beautifully. It's exactly what I wanted to add a genuine raw gem to my collection.

I was blown away by the deep, natural blue color of this raw chunk—it’s so much more vivid than a polished stone. The crystalline surfaces catch the light beautifully from every angle.

The crystal structure on this piece is absolutely wild—you can see the natural faceting and raw matrix up close. It’s unpolished and earthy, which is exactly what I wanted for my collection, and the weight feels solid in hand.
