Aquamarine
Aquamarine, a variety of beryl, captivates with its enchanting light blue hue. Its name, derived from Latin, translates to “water of the sea.” Aquamarine is known for:
- Clarity and transparency, resembling pristine ocean waters
- Hardness (8 on Mohs scale), making it durable for jewelry
- Pleochroism, exhibiting slight color variations from different angles
Composition: Be3Al2Si6O18
Crystal System: Hexagonal
Specific Gravity: 2.68-2.71
Topaz
Topaz, an aluminum silicate mineral, boasts a diverse range of colors, including light blue. Its name originates from Sanskrit, meaning “fire.” Topaz is distinguished by:
- Richer blue color compared to aquamarine
- Higher hardness (8 on Mohs scale), providing exceptional resilience
- Permanent color, unaffected by heat or light
Composition: Al2SiO4(F,OH)2
Crystal System: Orthorhombic
Specific Gravity: 3.49-3.57
