London Blue Topaz: A Darker Blue Hue for You
In comparison with sapphire and aquamarine gemstones, London blue topaz is relatively inexpensive and, therefore, is becoming a favorite for many jewelry/gem enthusiasts. In addition to the prices for London blue topaz, people are falling in love with its beautiful color. London blue topaz is a term given to the darkest shade of blue topaz gemstone.
 Blue topaz is the official gemstone of the state of Texas. Blue topaz is categorized by three names, depending on the richness of blue color: London blue topaz, sky blue topaz, and Swiss blue topaz. Swiss blue topaz is the lightest blue color, followed by sky blue topaz and, as mentioned before, London blue topaz, which has the darkest blue hue.
The topaz gemstone is the birthstone for the months of November and December. Yellow topaz is the modern birthstone for November, while blue topaz is the modern birthstone for December. Topaz is an acceptable stone for the 4th, 19th, and 23rd wedding anniversary.
Topaz has been discovered in the United States, Myanmar, Australia, Mexico, Japan, Africa, Sri Lanka, Brazil, Pakistan, and Russia.
Blue topaz is sometimes found naturally, but the majority of blue topaz (which includes that gorgeous London blue topaz) is created from irradiation, followed by heat treatment of colorless or silver topaz. Of the topaz gemstones, red is the rarest and most expensive, followed by pink, imperial (orange/red), then yellow and yellow/brown, and finally, blue.
At 8.0 on the Mohs scale, London blue topaz is great for any type of
jewelry. However, avoid hard hits on the stone. London blue topaz could split when subjected to those intense blows. Internal splitting could occur if the gemstone is heated or cooled too quickly. Also, avoid prolonged exposure to heat or bright lights. This could cause the color to fade. Ultrasonic or steam cleaning should not be used. Instead, use warm, soapy water and a soft brush. London blue topaz is usually quite clear and should not be purchased if there are too many inclusions in the stone.
Historically, Egyptians wore topaz to prevent injury. People of the Middle Ages believed topaz could heal mental and physical ailments and prevent death. The Greeks believed the topaz gemstone would make them stronger and invisible. The Romans believed it would enhance their eyesight. But, perhaps the most intriguing of all, some people held the belief that topaz would change its color when it was close to food or drink that had been poisoned.
So, if you haven’t been inclined up to this point to obtain London blue topaz,
perhaps you might agree that it might be an asset to have when trying someone’s cooking for the first time. If, by chance, the London blue topaz doesn’t change its color (and your food or drink is indeed poisoned), at least you’ll look sensational and hopefully have a great time.
