This is a classic style of Guerrero amethyst, with snow white tips grown over grape-juice colored cores. The contrast is striking, unusual, and nearly unique to this location in terms of drama (it happens at Brandberg, too). This particular piece is really 3-dimensional, with two clusters growing at slight angles relative to one another and joining in the middle. I love the overall effect of geometry here...it is very striking in person. The major tips and all important parts are in pristine condition. There is some slight contacting around the edges, and the smallest crystal in the back of the cluster is (I suspect) repaired but is the most trivial one, anyhow. Nevertheless, the display is impactful, the piece is of good size, and the snow white tips really make this a special and dramatic specimen. Material like this hasn't been dug up in decades, and is hard to find today on the market. Joe Budd photos
