I love crystals and gems, and have been collecting for quite some time. I’ve spent quite a bit of money on these natural beauties, as well as on some fakes. In the years of loving crystals, I’ve learned so much about them, including how to spot a fake or heated crystal.
Bright pink, purple, and green, as well as deep blue agate is dyed. While most sellers will state that they are dyed, their are quite a few that try to pass them off as natural.
Amethyst, Citrine, or Rose Quartz with super saturation color
If the color is uniform and vibrant, it is dyed. The dye will usually build up in the cracks and is quite noticeable.
Ametrine is a lovely combination of amethyst and citrine. It is decently expensive and very easy to fake. If you see anything labeled as ametrine and the two colors are half and half, in a straight line, it is fake. Natural ametrine has splotches of color. Below is a picture of natural ametrine.
Any crystals with these names are scams and fraud. Sellers have added a fancy name to white quartz (which is cheap) and put on a ridiculous price, claiming they are from rare mine. It’s shenanigans.
Black obsidian can easily be faked by dyed glass. Black obsidian has a glassy feel, so by looking, it can be a bit difficult q determine if it is a fake. But, obsidian is noticeably heavier than glass. Below is a natural black obsidian wand.
Amethyst is very common, so common that sellers try to find a new way of marketing it. Like heating it, causing it to turn a dark citrine color. Fake citrine is much darker and is commonly sold on druzies. Real Citrine does NOT grow on a druzy.
I think clear quartz is one of the most commonly faked crystals out there today. Since quartz is clear, glass is a great substitute. Glass is amorphous, meaning it cools down to fast and the molecules won’t arrange themselves in a crystalline pattern. Quartz cools slowly, so it has a perfect geometric molecular structure. If it is clear with no cracks or imperfections, and it’s under $10, it’s fake. Crystal balls and wands the most frequently faked. Below are natural clear quartz wands and a glass crystal ball.
Fruit Named Quartz
Sometimes red-colored fire quartz or harlequin quartz has been called “strawberry”, but as a general rule, strawberry, cherry, blueberry, etc, quartz are fake and nothing more than dyed glass.
Opalite is a cheap, man made crystal and is often passed off as opal or moonstone. Natural opal generally has flakes, is shiney, and is more than one flat and solid color. Moonstone is iridescent, has “layers” of color, and isn’t a dull clear color. Below are opalite wands.
Smelt quartz is a dyed quartz or glass. They usually come in red or blue, and are often labeled as smelt, cherry, or other fruit names. The color comes from metal that is added when the quartz or glass is in a liquid state.
Smokey quartz is faked by radiation, not heat (like some sellers will try to tell you). Heat cannot give quartz it’s smoke color. Faked smokey quartz is either black, has a white base, dull and flat color, and is not transparent or translucent.
Sugilite is known for it’s rich purple color and is very expensive. Some common names for fakes are flower sugilite, Russian sugilite, Chinese sugilite, or sugilite jasper. If it’s a dull, uniform purple color with black streaks, it is a fake. If it’s named sugilite “crystal” and is bigger than tiny, it is a fake. Some cheap stones that have been passed off as sugilite are : purple kiwi jasper, purple crazy lace agate, charoite, purple howlite and purple magnesite.
Dyed magnesite and howlite both look very similar to turquoise. Even when undyed, they’ve been passed off as “white turquoise”. Reconstituted turquoise is turquoise powder, resin, and dye pressed into a mold or carved.
Here is a chunk of my natural crystal collection. While some fakes aren’t bad, opalite and sandstone, natural is the way to go.
Keep in mind, all of these are based on my opinions I found from my research. You may disagree or have something to add. Please do so kindly in the comments.
Blessed be, brothers and sisters.
