By Anna Duncan

London Blue Topaz is a beautiful gemstone that has become increasingly popular in recent years. However, with the rise of synthetic gemstones, it can be challenging to determine whether a London Blue Topaz is real or not. In this article, we will discuss some tips on how to tell if your London Blue Topaz is genuine or not.

What is London Blue Topaz?

London Blue Topaz is a variety of blue topaz that has a deep blue color. It is often heat-treated to achieve this color and can range from a light blue to a dark, almost blackish-blue hue. This gemstone is also known for its durability and affordability, making it an excellent option for both jewelry enthusiasts and those who are just starting their collection.

How to Tell if Your London Blue Topaz is Real

Here are some ways to determine if your London Blue Topaz is genuine:

  • Color: The color of the gemstone can be an essential factor in determining whether it’s real or not. A genuine London Blue Topaz has a deep blue color that almost looks like the ocean.
  • Inclusions: Look for any inclusions or flaws within the stone.

    Genuine London Blue Topazes have small inclusions that are visible under magnification.

  • Cut: The cut of the gemstone can also tell you whether it’s real or not. A genuine London Blue Topaz will have clean edges and sharp facets.
  • Weight: You can also check the weight of the stone as a genuine London Blue Topaz will have a higher density than synthetic ones.

Distinguishing Between Synthetic and Natural Gemstones

While these tips can help you determine whether your London Blue Topaz is genuine or not, it’s essential to note that synthetic gemstones have become increasingly sophisticated. Here are some ways to distinguish between synthetic and natural gemstones:

  • Price: Synthetic gemstones are often much cheaper than natural ones.
  • Inclusions: Synthetic gemstones do not have the inclusions that natural ones do, and they often appear too perfect.
  • Color: While synthetic gemstones can mimic the color of natural ones, they often lack the depth and complexity of a genuine gemstone.

Caring for Your London Blue Topaz

Whether you have a genuine or synthetic London Blue Topaz, caring for your gemstone is essential to maintain its beauty. Here are some tips on how to care for your London Blue Topaz:

  • Cleaning: Use warm soapy water and a soft brush to clean your gemstone. Avoid using harsh chemicals or ultrasonic cleaners as they can damage the stone.
  • Storage: Store your London Blue Topaz in a soft cloth or jewelry pouch to prevent scratches and damage from other jewelry pieces.
  • Avoid Exposure: Keep your gemstone away from heat, light, and chemicals like perfume or hairspray as they can damage the stone.

The Bottom Line

Determining whether your London Blue Topaz is genuine or not can be challenging, but with these tips, you can make an informed decision. Remember that synthetic gemstones have become more sophisticated over time, so it’s crucial to purchase from reputable jewelers who can guarantee their products’ authenticity. Proper care of your London Blue Topaz will ensure that it remains beautiful for years to come.
