Gemstones have captivated humans for centuries with their beauty and symbolism. Among the numerous gemstones that adorn jewellery, Blue Topaz and Aquamarine are two popular choices known for their captivating blue hues. While they may appear similar at first glance, there are significant differences between these gemstones. Let’s explore the unique characteristics of Blue Topaz and Aquamarine and understand what sets them apart.
Origin and Formation
Blue Topaz is a variety of the mineral Topaz and is commonly found in countries such as Brazil, Sri Lanka, and Nigeria. It occurs naturally in a range of colours but is usually subjected to heat treatment to achieve the stunning blue shades that are highly sought after in jewellery.

Aquamarine, on the other hand, is a variety of the mineral Beryl. Its name is derived from the Latin words “aqua” (water) and “marina” (sea), signifying its captivating sea-blue colour. Aquamarine is typically found in countries like Brazil, Colombia, and Madagascar.
History and Traditions of Aquamarine and Blue Topaz
Aquamarines have a vast and rich history that dates back centuries. The gemstone was highly prized by the ancient Greeks and Romans, who believed it to be a symbol of the sea and associated it with the god of the sea, Poseidon/Neptune. They believed that wearing Aquamarine would ensure safe passage and protect sailors from the perils of the ocean. In ancient times, Aquamarine was also thought to possess mystical powers and was used by seers for divination and scrying. It was believed to enhance spiritual awareness and provide clarity of thought. Additionally, it was regarded as a stone of courage, believed to instill strength and protect against enemies in battle.

Blue Topaz history, on the other hand, is much more recent. It wasn’t until the 20th century that Blue Topaz gained significant popularity. In the 1960s, large deposits of colorless and pale-yellow Topaz were discovered in Brazil. To enhance its market appeal, the gemstone was treated with heat and irradiation to produce the vibrant blue colours that are now associated with Blue Topaz. This treatment process transformed the gemstone into a highly sought-after and affordable alternative to other blue gemstones.
