Osman Ali Khan's Gold Scales

Origin
Osman Ali Khan was the last Nizam or ruler of Hyderabad before it was annexed into India. He was recorded as one of the richest men in history, with his own mint, currency and treasury along with millions in gold, silver and jewels. He also owned the Jacob Diamond, estimated at £100 million ($133 million), which he just used as a paperweight.

Effects
A set of weight scales used to weigh gold for the Nizam when new gold came in, testing if it was fake or not. The scales have the power to detect false currency, jewels or gold, swaying to one side if real and swaying to the other if fake.
