Record keeper triangles are natural triangular markings that appear on some quartz faces. On Ita's amethyst wand, they remain visible because the termination was left unpolished.
The long, tooth-like profile is often called an amethyst wand or amethyst tooth. Those are collector names, not separate mineral varieties. Mineralogically, it is a naturally terminated crystal of amethyst, the purple variety of quartz.
Its original faces, texture and triangular markings remain visible because the point was not re-cut or polished.
How does an amethyst tooth form?
The shape begins when quartz grows into open space within rock. Silica-bearing fluid enters the cavity, and the crystal adds material layer by layer. With enough room, it can develop an elongated prismatic body and angled faces at the top.
Those terminal faces are mainly rhombohedral. Where they meet, they create the pointed profile that gives the crystal its tooth-like appearance. It may look like a carved pyramid, but the geometry belongs to the quartz.
The violet color developed through another part of the same history. Trace iron entered the quartz structure as it grew. Natural background radiation later created the color centers responsible for amethyst's purple.
Why an unpolished point is different
Polishing is a lapidary choice. It can create a clean and controlled symmetry, but it also changes the original surface.
On this piece, the termination was left natural. Its faces were not re-cut to look sharper or more even. The subtle changes in texture and geometry belong to the crystal, allowing details that polishing could soften or remove to remain visible.
What are record keeper triangles?
Across several faces of this amethyst, small triangles appear on the natural termination. Collectors call them record keepers.
The name sounds mysterious, but the geometry has a mineralogical explanation. Quartz has trigonal symmetry, and triangular patterns can develop as layers advance during growth or retreat during later dissolution. A raised triangle may be a growth hillock. A recessed one may be an etch pit.
Without examining every mark under magnification, it would be careless to claim that one process formed them all. What we can say is more interesting: they are natural surface features, and the unpolished point has preserved them.
This wand is not special because someone made its point perfect. It is special because its natural point was worth preserving.
