Calculate the value of your precious metals instantly using live market prices.
Essential knowledge for every investor, jeweler, and gold enthusiast. Understanding precious metals helps you make smarter buying and selling decisions.
A troy ounce (31.1035 grams) is the standard unit for measuring precious metals worldwide. It differs from a regular ounce (28.35g) and has been used since the Middle Ages. When you see gold or silver prices quoted internationally, they always refer to the troy ounce. Understanding this distinction is crucial for accurate trading and valuation of precious metals.
Gold purity is measured in karats (K). Pure gold is 24K (99.9% gold). 21K contains 87.5% gold mixed with metals like copper and silver for durability. 18K has 75% gold, making it ideal for jewelry that needs strength. The remaining percentage consists of alloy metals that give gold different colors and hardness levels suitable for daily wear.
Fine silver (999) is 99.9% pure silver, too soft for most practical uses. Sterling silver (925) contains 92.5% silver and 7.5% copper, offering the perfect balance of beauty and durability for jewelry and silverware. When investing, fine silver bars and coins are preferred, while sterling silver is the standard for crafted items and everyday accessories.
Gold prices are influenced by multiple factors: inflation rates, currency strength (especially USD), central bank policies, geopolitical tensions, and market demand. Gold typically rises during economic uncertainty as investors seek safe-haven assets. Supply from mining and recycling also plays a role. Monitoring these factors helps predict price movements and timing for purchases.
Gold has been a store of value for over 5,000 years. It serves as a hedge against inflation and currency devaluation. Investors can buy physical gold (bars, coins, jewelry), gold ETFs, mining stocks, or gold futures. Physical gold offers tangible security, while financial instruments provide liquidity. Diversifying with 5-15% gold allocation is a common portfolio strategy.
Authentic gold can be verified through several methods: hallmark stamps indicating karat, acid testing kits, electronic gold testers, and specific gravity tests. Genuine 24K gold has a density of 19.32 g/cm³. Professional jewelers use X-ray fluorescence (XRF) analyzers for precise readings. Always buy from reputable dealers and request certificates of authenticity.

Expert advice to help you get the best value when dealing with precious metals.
Before any transaction, compare the dealer's price with the current international spot price. Our live tracker above gives you real-time reference prices.
Dealers charge a premium over spot price for coins and bars. This covers manufacturing, shipping, and profit. Typical premiums range from 2-10% depending on the product.
Always verify the karat stamp and weigh items on a certified scale. A difference of even 1 karat significantly affects value. Use our calculator app for precise valuations.
Store all purchase certificates, receipts, and authenticity documents safely. These are essential for insurance claims, reselling, and proving provenance of your metals.
Don't put all your investment in one type. Mix between gold bars, coins, and jewelry. Consider adding silver for portfolio diversification and lower entry costs.
Monitor price trends and buy when prices drop. Gold prices typically cycle with economic events. Patience and timing can save you significant money on purchases.
