Color: see above. U.V. Fluorescence: weak; blue and colorless topaz may show a weak yellow or greenish glow under long wavelength u.v.. Sherry-brown, pink, or golden yellow topaz may show a strong orange-yellow fluorescence under long wavelength u.v. light that is much weaker under short wavelength u.v. light.
Ruby and topaz are two of the most photoluminescent gemstones. They appear to glow subtly in indoor or outdoor lighting. Some of the glow you're seeing is actually photons emitted from electrons in the gem – so yes, they do "glow!"
Some minerals glow or fluoresce under ultraviolet (UV) light, such as some shown here. Apatite, quartz, orthoclase feldspar, and muscovite under normal white light and UV light.
There are a few easy ways to tell a real topaz apart from quartz. The first characteristic to keep in mind is the hardness factor. An original topaz will scratch glass while quartz will not leave a mark on it. Moreover, a real topaz is also cool to touch and it gets electrified easily.
Natural blue topaz doesn't glow under UV light. I suspect that the gems are synthetic spinel, which definitely glows under UV.
U.V. Fluorescence: weak; blue and colorless topaz may show a weak yellow or greenish glow under long wavelength u.v.. Sherry-brown, pink, or golden yellow topaz may show a strong orange-yellow fluorescence under long wavelength u.v. light that is much weaker under short wavelength u.v. light.
The most remarkable insightful details is the light and refraction lines (the way light reflects in many directions). If the refraction are more than two lines in your blue stone, it's likely a blue topaz.. Blue topaz is a hard gem, with a Mohs hardness of 8. In spite of its hardness, it should be handled with care.
Although frequently associated with golden yellow as well as blue, it can be found in a variety of colors, including colorless. The rarest are natural pink, red, and fine golden orange, sometimes with a pink tone. The traditional November birthstone, topaz is a popular gem.
Common topaz in its natural state is colorless, though trace element impurities can make it pale blue or golden brown to yellow orange. Topaz is often treated with heat or radiation to make it a deep blue, reddish-orange, pale green, pink, or purple.
A milky or cloudy appearance is usually caused by air bubbles in the water, which pose no health risk. If the water is allowed to sit, the air will dissipate and the water will clear. If the cloudiness does not disappear, please contact us so that we may investigate.
Fluorescence: Sapphires of any color can fluoresce under long wave UV light if iron content is low enough that it doesn't quench fluorescence. Fluorescence colors include pink and red (due to chromium) and orange (due to F-centers or crystal lattice defects according to Vigier & Fritsch, 2023).
Both natural and synthetic rubies fluoresce under UV light.
Ultraviolet Light: About 30% of diamonds will glow blue under ultraviolet lights such as black light. Fake diamonds, on the other hand, will glow other colors or not at all.
Topaz Glow creates vibrant and beautiful images with energetic sparks of neon light. Your images have hidden textures that aren't visible to the naked eye. Topaz Glow illuminates these hidden contours in a very special way.
Topaz is a fluoro-silicate of aluminium, usually colourless, but can be white, yellow, light shades of grey, blue, orange, brown, green or pink. Unlike other gem stones, it is not always the impurities in the crystal that give topaz its colour.
A well cut topaz reflects a large amount of light off its facets. Just like diamonds, topaz has a perfect cleavage hence has a magnificent sparkle. A poorly cut topaz will not reflect light well and will also have a dull look.
Aquarius. The lord of Aquarius is the planet Saturn. Due to being second lord i.e. strong Marrakesh and Ekadesh in this zodiac, it is inauspicious. For this reason, people of the Aquarius zodiac should also not wear topaz.
Swiss blue is one of the prettiest and most popular of the blue topaz with its intense blue color range. Described as vibrant, electric, or super blue, Swiss blue topaz can be compared to the rich colors of the Caribbean Sea.
Natural topaz is found as crystals that are considerably larger than those of many other precious stones. Consequently, its per-carat price does not rise much as the size of the gem increases. It is therefore an affordable precious, blue stone that adapts well to larger jewellery.
Blue topaz and colorless topaz are very affordable and widely available. Red, pink and orange colors are rare and valuable.
The most valuable topaz is a rich pink or red color, and can reach $3500/ct. at retail. These are rare in sizes above 5 cts.
High heat or sudden temperature changes can cause breaks in topaz. The gem's color is generally stable to light, but prolonged exposure to heat or sunlight might cause fading in yellow-to-brown, reddish brown, or dark brown topaz. Topaz is affected only very slightly by chemicals.
Does Blue Topaz Fade? According to the GIA, blue topaz's color is stable to light, so it won't fade or change colors.
Is a blue topaz valuable? Large dark blue stone can be very expensive, price up to $ 100 per carat. And small light blue topaz stone price can cost only a few dollars per carat.
Aquamarines are far more expensive when compared to Topaz or other stones. Derived from Latin words meaning 'seawater', these gemstones have a brief history of being considered sacred in Roman and Greek empires.
