Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain the garnet group, relay its structure, members and uses from mineralogy sources, describe the members its aliases name, and distinguish garnets from other silicate minerals.

A group of silicate minerals, the garnets, that share a common crystal structure but vary in composition, typically forming hard, glassy, many-faced crystals in a range of colours; the registry aliases name members and related mineral groups such as majorite and goldmanite. Garnets are used as gemstones and as industrial abrasives, and the group name covers several species distinguished by their metal content.

What it is for: Not applicable; a group of silicate minerals.

It can be explain the group; relay structure and members; relay uses; distinguish it from other silicates.

Distinguishing features

Shared crystal structure

Varied composition and colour

Hard crystals

Gem and abrasive use

What it looks like

Hard, glassy crystals with many faces, commonly deep red but also green, orange and other colours.

How it is recognised

Hard many-faced silicate crystals

Majorite, goldmanite and other garnet members

What the second pass must settle

  • Should garnet species be separate entries?
  • How should the supergroup be linked?
  • How should gem and industrial uses be scoped?
