How to identify garnet: Garnet is relatively rare in imitations, making it easier to distinguish. Here are four key points to help you identify genuine garnet: 1. If the color is overly bright and ultra-clear, and the price seems too good to be true, there may be issues. Authentic garnets usually have a natural and balanced appearance rather than an artificial shine. 2. Look for impurities such as "cotton wool" or black spots. Garnets often contain small inclusions like black specks or ice-like cracks, which are normal and not signs of fake stones. 3. Garnet is heavier compared to most other gemstones. If the stone feels lighter than a typical crystal, be cautious—it might not be real. 4. The surface of a genuine garnet feels smooth and slightly oily to the touch. It has a cool sensation when held in your hand, unlike the cold, glassy feel of synthetic crystals. Gemstones that can resemble garnet include rubies, red spinels, and others. Rubies are typically heterogeneous with dichroism, show chromium absorption lines, and may exhibit fluorescence. They can also have needle-like inclusions forming a 120° angle. Spinels, on the other hand, have lower refractive indexes and may display octahedral inclusions under magnification. Garnet is homogeneous and does not show dichroism. It does not react under a Charles filter and may have horsetail-like inclusions. High-quality water calcium aluminum garnet appears bright green and closely resembles jade. It often contains black spots and has a refractive index of around 1.73. Unlike jade, it lacks characteristic absorption bands in the red spectrum.
