Red Cap Amethyst — Hematoid Quartz Crystal Cluster, Iron Inclusions, 2.78 lbs — Field Find

THE FIND
A red cap amethyst cluster, 2.78 lbs — also known as hematoid quartz, this specimen blends the violet of amethyst with the warm red-gold of iron oxide inclusions throughout the crystal structure. The result is a formation that looks like a captured sunset inside stone. A substantial display piece.

WHAT WE KNOW
Red cap amethyst (hematoid quartz) forms when iron oxide — typically hematite or goethite — integrates into growing quartz crystals, producing red, orange, or golden coloration within or coating the crystal points. In this specimen, the iron inclusions interact with the amethyst coloration to create the layered, smoky, warm-toned effect characteristic of the material. The cluster weighs 2.78 lbs and displays multiple crystal points with visible iron inclusion coloration. Locality not independently verified.

THE STORY
Hematoid quartz occupies an interesting position in mineralogy — it’s not a single mineral but a combination: quartz carrying iron oxide inclusions that alter its appearance without changing its fundamental crystal structure. The “red cap” variety specifically refers to specimens where the iron coloration concentrates at or near the crystal terminations, producing the characteristic warm-tipped points. At 2.78 lbs, this cluster has the mass to be a centerpiece specimen rather than a shelf accent.

WHY WE CHOSE IT
The contrast between the violet amethyst base color and the iron-red inclusions is what makes hematoid quartz worth seeking out — and this specimen shows that contrast clearly. The size gives it real presence. A collector-grade piece at a fair price.
