Understanding Aquamarine
Aquamarine is a member of the beryl family, which also includes emerald. It derives its name from the Latin words aqua (water) and marina (sea), reflecting its soothing ocean-like blue-green shades. Its color comes from trace amounts of iron in its crystal structure. With a hardness of 7.5 to 8 on the Mohs scale, aquamarine is durable and ideal for rings, necklaces, and earrings. Known for its clarity, aquamarine has been prized throughout history as a symbol of peace, courage, and emotional balance.
Understanding Blue Topaz
Blue topaz is a variety of the mineral topaz, naturally occurring in pale colors but often treated with heat and irradiation to achieve vivid blue shades. It is one of the most popular gemstones on the market due to its affordability and availability. Blue topaz ranks 8 on the Mohs hardness scale, making it slightly harder than aquamarine. It is widely admired for its bright color, which ranges from sky blue to deep London blue, and is often used in bold, modern jewelry designs.
