正四面體柏拉圖立體 - 白水晶（巴西）

The edges are so crisp and precise, you can really feel the geometry in your hand. It's heavier than I expected for its size, which makes it feel substantial on my shelf. The clarity is beautiful too, catching the light in a way that makes the whole piece glow.

Holding this tetrahedron in natural light, you can see tiny rainbows forming inside the quartz—it's clearer than I expected. The weight feels substantial, perfect for sitting on my desk as a conversation piece.

The facets are cut so precisely that light catches every edge when it's on my shelf, and the Brazilian quartz has that lovely internal clarity you don't see in cheaper stones. It's a simple piece, but it anchors my collection perfectly.
