What are some ways you could describe a gold ring that are not properties of gold?

The possible and mostly used ways to describe gold ring which is not property of gold are;

(a) Touchstone kit

(b) Density Test

Explanation:

Touchstone Kit

A touchstone kit is used to check gold which is simple in use and inexpensive. The kit contains a block of fine-grained black stone which is called the touchstone. Set of probes tipped with small standard alloy amount and small quantities of test chemicals. The chemical contains nitric acid, hydrochloric acid and aqua regia. Acid in a kit can cause of burn so needed to handle carefully.

Density Testing

A density of a substance is its mass per unit of volume. Pure gold contains 19.3 grams density per cubic centimeter. In comparison to this, water density is 1 gram per cubic centimeter. There are three ways to calculate density. The easiest method is to weigh the sample and measure the volume of it.
