電氣石 - 黑碧璽雙晶/晶簇「特級」（巴西）

I was impressed by the cluster's natural shape and the deep, glossy surfaces that catch the light. The piece is heavier than I expected, which makes it feel substantial in hand.

The crystalline structure on these black tourmaline clusters is incredibly sharp and well-defined, with each piece having a natural, raw beauty. I was impressed by the size and weight of the specimens for the price—these feel substantial. My only minor note is that a few tiny fragments came loose in

The "Extra" grade really shows in these pieces - the crystal formations are dense and well-defined, with that deep, almost metallic black that catches light beautifully. I've got mine displayed on a shelf and the natural cluster shape works perfectly as a statement piece.
