This is a professional set designed for testing the authenticity and purity of gold, silver, and platinum. It allows you to quickly and reliably determine whether an item is made of genuine precious metal and its exact karat or fineness.
The kit works by using special testing acids and a testing stone. A trace of the metal is rubbed onto the stone, and a drop of the corresponding acid is applied. By observing the reaction – whether the mark dissolves, changes color, or remains unchanged – you can determine the metal’s type and purity.
This is one of the oldest and most reliable testing methods, widely used by:
pawnshops,
jewelers,
collectors,
precious metal dealers,
antique appraisers.
With this kit you can:
distinguish real gold from fakes,
identify the karat of gold (from 8k to 21k),
verify the authenticity of platinum (only platinum resists the special acid),
test whether an item is silver and determine its quality.
Set includes:
Gold testing acids: 8k, 14k, 18k, 21k (20 ml each)
Platinum testing acid (20 ml)
Silver test solution 1 (5 ml)
