Silver purity is a crucial factor when purchasing silver, as it determines the metal's quality and value. Purity is typically expressed in fineness, indicating the percentage of pure silver in an alloy. For instance, 999 fineness means 999 parts out of 1000 are pure silver. Fine silver, also known as .999 silver, contains 99.9% pure silver and is ideal for investment coins and bars due to its high resistance to tarnish. However, its softness makes it unsuitable for everyday jewellery.
Sterling silver, with 92.5% purity, is the global standard for jewellery and silverware. It combines 92.5% silver with 7.5% other metals, usually copper, to enhance durability. Britannia silver, introduced in Britain in 1697, offers a higher standard with 95.8% purity, while coin silver, containing 90% silver, was historically used in coins.
When purchasing silver, the final price includes the base silver rate plus making charges and a 3% GST. For studded jewellery, the weight of embedded stones is excluded when calculating the net silver weight. Authenticity can be verified through BIS hallmarking, which includes a purity grade such as 925 for sterling silver or 999 for fine silver.
Investors looking to avoid physical storage and making charges can consider digital silver or silver ETFs. Digital silver allows for online purchases without physical delivery, though it is not regulated by SEBI, which has issued warnings about potential risks. Silver ETFs enable investors to buy and sell silver like stocks on exchanges, tracking domestic silver prices subject to tracking errors.
