Aquamarine — Gemstone Properties
Aquamarine is a blue-green variety of beryl whose serene colour evokes clear tropical waters and open skies. Its name comes from the Latin "aqua marina" — sea water. Sailors historically wore aquamarine as protection on sea voyages, and today it symbolises clarity, courage, and serenity. Its colour ranges from pale sky blue to deep teal, caused by trace iron within the beryl structure. March's birthstone.
How can I tell Aquamarine from Blue Topaz?
Both are beautiful blue gems, but they differ in hue and hardness. Aquamarine has a characteristic blue-green (seafoam) tint; blue topaz tends toward a brighter, more saturated pure blue. Aquamarine (Mohs 7.5–8) is slightly softer than topaz (Mohs 8). Under magnification, their inclusions and optical properties differ.
Is Aquamarine heat-treated?
Most aquamarine is heat-treated to reduce its greenish component and intensify the pure blue colour. This is a standard, stable, and permanent treatment widely accepted in the trade. The resulting colour does not fade or revert.
What does Aquamarine symbolise?
Aquamarine is associated with the sea, courage, and clear communication. It is traditionally linked to the throat chakra and is thought to help wearers speak their truth with calm and clarity. It is also a stone of protection during travel.
How hard-wearing is Aquamarine?
Aquamarine rates 7.5–8 on the Mohs scale, making it a relatively durable choice suitable for all jewellery types including rings. It is harder than quartz but softer than sapphire. Avoid wearing alongside diamond-set pieces that could scratch the surface.
