Gold has been a highly coveted precious metal since time immemorial. However, pure gold is too soft to be used in jewelry, so it is mixed with other alloys to create a more durable material. Gold can come in different colors, including yellow, white, and rose, and even other rarer shades, depending on the alloys used. The value of gold is measured in carats, with a higher carat number indicating a higher purity of pure gold.
Silver is another popular precious metal, appreciated for its versatility and bright gray shine. It’s the most commonly used and accessible metal in jewelry. Like gold, pure silver must be mixed with other metals to make it harder when used in jewelry making. Sterling silver, containing at least 80% pure silver, is the most commonly used type of silver. Silver jewelry is often marked 950, 925, or 800, depending on the percentage of pure silver they contain.
Platinum is the most expensive of precious metals due to its rarity. Like gold and silver, it’s mixed with other metals for jewelry making. Platinum has a beautiful silvery-white luster and is extremely durable, making it highly resistant to time and scratches. A “pure” platinum piece of jewelry must contain at least 90% platinum. Platinum is often used in the making of wedding rings and engagement rings due to its durability and symbolism of eternity.
