Gemstones are minerals that have been chosen for their beauty and durability, then cut and polished for use as human adornment. Of course, there are exceptions to this definition. Pearls and amber are well-known gemstones but they’re not minerals. They have organic origins.

All gemstones have something appealing about them, whether that’s their appearance, their symbolism, their rarity, or an unusual physical or optical property. However, not all gems make good jewelry stones. Some are just too fragile to wear. Here at Chalfen of London we deal mainly with the following precious stones and gemstones.
