The Origins of Aquamarine and Topaz

Where Aquamarine is Mined

Aquamarine is primarily mined in Brazil, which is known for producing some of the highest quality stones. Other significant sources include Kenya, Madagascar, Pakistan, Afghanistan, and Zambia.

Where Topaz is Found

Topaz is found in various locations around the world, including Brazil, Nigeria, Sri Lanka, and Russia. The gemstone is more abundant and accessible compared to aquamarine, contributing to its lower price point.

Physical Properties of Aquamarine

Color and Clarity

Aquamarine is prized for its stunning light blue to blue-green color, which is reminiscent of the ocean. The color is usually even and can range from pale to vibrant hues. The stone is also known for its excellent clarity, with minimal inclusions.

Hardness and Durability

On the Mohs scale, aquamarine has a hardness rating of 7.5-8, making it a durable choice for everyday wear. However, it’s essential to note that aquamarine can have fragile cleavages, so it should be handled with care to avoid chipping or cracking.

Chemical Composition

Aquamarine belongs to the beryl family and has a chemical composition of Be₃Al₂(SiO₃)₆. The presence of iron within its crystal structure gives aquamarine its characteristic blue color. Unlike many gemstones, aquamarine often requires minimal treatment to achieve its desired hue.

Though she was only seen wearing this dramatic aquamarine ring a few times, including at an auction for Christies in 1997, Princess Diana’s cocktail stunner really made an impact. It is believed to have been commissioned by the late princess to match an aquamarine and pearl bracelet in her collection.

Physical Properties of Topaz

Colour and Clarity

Topaz is a versatile gemstone that comes in various colors, including blue, pink, yellow, green, and even colorless. Blue topaz is particularly popular, especially the shades known as “Swiss Blue” and “London Blue.” Topaz generally has good clarity, though inclusions can be present in some stones.

Hardness and Durability

Topaz is rated 8 on the Mohs scale, making it one of the harder gemstones available. This hardness makes it suitable for various types of jewelry, from rings to necklaces. However, topaz can have perfect cleavage, which means it can split along specific planes if struck.

Chemical Composition

Topaz is a silicate mineral with the chemical formula Al₂SiO₄(F,OH)₂. Its diverse color range is due to the presence of trace elements and treatments. For example, blue topaz is often produced through irradiation and heat treatment of colorless or pale topaz.

“Aquamarine stones usually undergo a lot fewer treatments to achieve the coveted color compared to blue topaz. When a stone undergoes multiple treatments, its value also decreases significantly.”

Besides its captivating beauty, aquamarine’s limited need for treatments significantly adds to its value. Unlike blue topaz, which often undergoes multiple treatments to achieve its vibrant hues, aquamarine’s color is typically natural. This makes aquamarine a more sought-after gemstone in the market.

Market Demand and Price

The market demand for aquamarine is relatively high due to its natural color and fewer treatments. Prices for aquamarine can vary widely based on factors such as color intensity, clarity, and carat weight. High-quality aquamarine stones with deep blue hues can command premium prices.

In comparison, blue topaz is more affordable and widely available. The lower price point makes it an attractive option for budget-conscious buyers who still want a beautiful blue gemstone.
