Most gemstones are made from minerals and are found in the Earth’s surface or much further towards the heart of the planet. Gemstones, with their exquisite colours and traditional meanings, make them precious to many. However, it is their rarity, hardness and durability that make them doubly valuable. Their natural beauty, colours and strength have inspired beliefs with supernatural origins and magical powers. There are over 3,000 different minerals, but only 50 are commonly used as gemstones. Others are often not suitable for wear because they are easily scratched or are too soft.
To be regarded as a gemstone, a mineral must be beautiful – most importantly in its colour. A gemstone must be durable – hard enough to survive constant use or handling without becoming easily scratched or damaged. Ultimately, a gemstone’s rarity adds greater market value. Throughout history, gemstones have been associated with wealth and power. Grahams carries many different types of gemstones, both natural and created. Grahams is proud to stock several pieces set with rubies, emeralds, sapphires, topaz and aquamarines.
