Blue topaz and London blue topaz are two of the most popular gemstones in the jewelry industry. While both of them share a similar name, they have some significant differences that make them unique. In this article, we will explore the differences between blue topaz and London blue topaz.
What Is Blue Topaz?
Blue topaz is a variety of the mineral topaz that is usually colorless or pale yellow. It gets its beautiful blue color from a process called irradiation, which involves exposing the stone to radiation to change its color. The intensity of the blue color can vary from light to dark, and it can be found in different shades such as sky blue, Swiss blue, and electric blue.
The Different Types of Blue Topaz
There are three main types of blue topaz:
- Sky Blue Topaz – This type has a light to medium blue hue that resembles the color of the sky.
- Swiss Blue Topaz – Swiss Blue Topaz has medium to dark blue hues and often has green undertones.
- Electric Blue Topaz – This type has a bright, vivid blue color that looks like an electric current running through it.
What Is London Blue Topaz?
London blue topaz is a type of treated or enhanced gemstone that is much darker than regular blue topaz. It is created by taking natural white or pale-colored topazes and treating them with heat and irradiation in a controlled environment. The treatment process results in a deep, rich shade of grayish-blue that is much darker than other types of blue topazes.
The Differences Between Blue Topaz and London Blue Topaz
The main difference between regular blue topaz and London blue topaz lies in their color. While blue topaz can range from light to dark blue shades, London blue topaz is always a deep, rich shade of grayish-blue. Another difference is that London blue topaz is more expensive than regular blue topaz due to its rarity and the complexity of its treatment process.
Which One Should You Choose?
When it comes to choosing between blue topaz and London blue topaz, it ultimately depends on personal preference and budget. If you prefer a lighter shade of blue with a more affordable price point, regular blue topaz may be the right choice for you. However, if you are looking for a deeper, richer shade of blue and don’t mind spending a bit more money, London blue topaz may be the perfect gemstone for your jewelry.
In Conclusion
In summary, both blue topaz and London blue topaz are stunning gemstones that make beautiful additions to any jewelry collection. While they share some similarities in terms of their chemical composition, they differ significantly in their color and price. Whether you choose regular blue topaz or London blue topaz depends on your style preferences and budget.
