London blue topaz is one of the most popular gemstones in the world, known for its deep blue color and stunning clarity. However, it is also one of the more expensive gemstones out there.
So what makes London blue topaz so pricey? Let’s take a closer look.
What is London Blue Topaz?
First, let’s define what we mean by London blue topaz. Topaz is a mineral that comes in a variety of colors, including yellow, pink, and blue.
The blue color in topaz comes from the presence of iron in the crystal structure. London blue topaz specifically refers to a darker shade of blue that has become very popular in recent years.
Why is it Expensive?
There are several factors that contribute to the high cost of London blue topaz:
Rarity
One reason why London blue topaz is expensive is because it is relatively rare. While topaz itself is not a rare mineral, finding high-quality specimens with the right shade of blue can be challenging. Most London blue topaz comes from Brazil, but it can also be found in other parts of the world such as Nigeria and Sri Lanka.
Treatment
Another factor that affects the price of London blue topaz is how it is treated. Most natural topaz does not have the deep blue color that we associate with London Blue Topaz.
Instead, it is often a pale or light yellowish-brown color. To achieve the desired shade of blue, the stone must be treated with heat and radiation.
This treatment process can be quite expensive and time-consuming, which adds to the overall cost of the stone. Additionally, there are strict regulations regarding how this treatment can be done to ensure safety and environmental responsibility.
Quality
Lastly, like all gemstones, London Blue Topaz is priced according to its quality. The most valuable stones will have a deep, even blue color with no visible flaws or inclusions. Lesser quality stones may have a lighter color or visible imperfections, which will lower their value.
Conclusion
In summary, London Blue Topaz is expensive due to its rarity, the cost of treatment, and the quality of the stone. But for those who appreciate its unique beauty and deep blue color, it is worth the investment. Whether you’re looking to add a piece of London Blue Topaz jewelry to your collection or simply admire its stunning hue from afar, this gemstone is sure to dazzle and impress.
