Amethyst: The Stone Of Protection And HumilityĪmethyst loses its violet color as it is heated to temperatures greater than 300-400C, and it becomes yellow, orange, or brown, with a natural quartz variety resembling citrine, but it can also become colorless or, at times, green depending on the species and where it is found What is burnt amethyst? The heat-treated citrine (also known as burnt amethyst) is baked at temperatures between 800-900 degrees Fahrenheit, transforming it into darker hues of orange depending on how long it has been exposed to heat. ![]() By doing so, you improve your ability to integrate new ideas and foster mental stability and strength. Amethyst is associated with serenity and calmness. This stone still contains amethyst’s healing properties, but it is no longer purple because the color of the stone corresponds to that of amethyst. Amethysts can be dyed pink, purple, or blue during heat treatment, but this is uncommon. Clear quartz contains many fluid or gas inclusions, which can cause it to appear milky, and amethysts may also exhibit this color. When amethyst crystals are heated, they glow green. Most amethysts do not change color when heated, but a few do. When amethyst is heated at a slightly higher temperature (1,500 to 575C) in the 500 to 575C region, the yellow color becomes more intense and the deeper orange, brown, or reddish color is more noticeable. What Does Amethyst Turn Into When Heated? Amethyst that has been heat treated will also be very clear, with few inclusions. You can tell if amethyst is heat treated if it has a deep, rich purple color. How Can You Tell If Amethyst Is Heat Treated? ![]() Heat treatment will have no effect on stone healing properties unless the color changes, which would occur only if the stone is used for color therapy. It goes from black to light green as the temperature rises to 420–440 C.Ī heat treatment is a chemical process that uses heat to lighten, darken, or change the color of a stone to make it more visually appealing. When the temperature rises above 380 C, the violet color fades and becomes colorless. To heat treat citrine (also known as burnt amethyst), a crystal is baked at temperatures ranging from 800-900 degrees Fahrenheit, and as the temperature rises, the color of the crystal changes, giving it deeper orange shades.Īmethyst color remains the same regardless of temperature at 360C. Amethyst can also be heated to produce a deep red color. Heated amethyst will often have a yellow or orange hue. The most common way to tell if amethyst has been heated is to look for color changes. When heated, amethyst can produce a range of colors from yellow to red. Gemological laboratories can also provide certification for your citrine, confirming its authenticity and providing additional information about its origin, treatment, and quality.Amethyst is a purple variety of quartz that owes its color to natural irradiation and iron impurities. They have the expertise and equipment to accurately assess the gemstone. To confirm the authenticity of your citrine, consult a professional gemologist or a reputable jeweler. Natural citrine is usually lighter in color. If you see colors that are a darker yellow/orange, then it’s likely that it’s a heated amethyst instead of natural citrine. If you see any bubbles in the piece, that piece is glass as natural citrine won’t have any.Ĭolors: Heat-treated amethyst often shows colors that are more intense color at the tips of the crystals and fading toward the base. Magnification: Under magnification, natural citrine may reveal inclusions or growth patterns, while glass will appear more uniform and free of flaws.A refractometer can help measure this property, but this test is usually conducted by a professional gemologist. Refractive Index: Real citrine has a refractive index of 1.54-1.55, while glass typically ranges from 1.45-1.50.A scratch test can help differentiate them, but it's not recommended as it can damage the gemstone. Scratch Test: Citrine has a Mohs hardness of 7, while glass is generally around 5.5.Glass beads that are imitations of amethyst, citrine and ametrineĭifferentiating Real Citrine from Imitations Real Citrine vs. ![]()
