24 karat gold is the highest possible gold available that can be fashioned into any shape easily. It has a higher resale value that makes it ideal for investment or extraordinary gifts. If you're interested in a family heirloom that will retain its value for generations, 24 karat gold may be the best option for you. This type of gold is quite soft and it becomes stronger and more durable with the addition of alloys and base metals, such as copper and silver. Compared to other types of gold, 24k gold is the purest form available, which makes it a favorite material for makers and collectors alike. Whether you are looking for unique gold coins, exceptional gold jewelry, or one-of-a-kind gold decorative objects, keep in mind that karat weight defines the appearance and longevity of any piece.
