Aquamarine is a beautiful gemstone known for its tranquil blue to blue-green color, reminiscent of clear ocean water. It is a variety of the mineral beryl, which also includes emerald and morganite. The name comes from the Latin aqua marinus, meaning “water of the sea.”

Here are its key features:

• Color: Ranges from pale sky blue to deep sea blue-green. The most prized stones are a vivid, pure blue.

• Clarity: Typically very transparent, often with few inclusions, giving it a bright, glassy luster.

• Hardness: 7.5–8 on the Mohs scale, making it durable enough for everyday jewelry.

• Formation: Found in granite pegmatites and sometimes in alluvial deposits.

• Major Sources: Brazil (most famous), Nigeria, Madagascar, Pakistan, and Mozambique.

• Symbolism: Associated with calmness, courage, and communication. Traditionally, sailors believed it protected them at sea.

• Use: Popular in rings, necklaces, and earrings; often cut into step cuts, ovals, or emerald cuts to highlight its clarity and brilliance.
