gold
Let an agent handle gold by properties, purity and hallmarking, uses, sourcing and scams, without investment advice.
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 handle gold by properties, purity and hallmarking, uses, sourcing and scams, without investment advice.
A dense, soft, yellow noble metal with chemical symbol Au and atomic number 79, highly resistant to corrosion, used in jewellery, coins and bullion, electronics, dentistry and gilding; its purity is measured in carats or fineness, and gold mining raises environmental and human rights concerns.
What it is for: Jewellery, money, electronics and decoration.
It can be explain purity measures and hallmarks; check whether gold items are genuine; understand responsible sourcing; avoid gold investment scams.
