Understanding how to identify jadeite starts with knowing the difference between A, B, and C grade jade. A few years ago, it was common for sellers to mislead customers by saying, "A-grade is top-quality jade, B-grade is second-grade, and C-grade is third-grade." Even today, you might still hear such claims. However, these terms are completely different from what most people think. A-grade jade refers to natural jade that has not undergone any artificial treatment. It retains its original color and texture, and is considered the real deal by most people. This is what we commonly refer to as genuine jade. B-grade jade is jade that has been treated with strong acid to remove impurities, then filled with resin or silicone to make it look clearer and more transparent. This type of jade is often called "shine jade" because of its glass-like appearance. However, the acid treatment destroys the natural structure of the jade, making it soft, brittle, and full of tiny holes. The fillers used can eventually oxidize over time, causing the jade to lose its clarity and become unrecognizable. Many people end up buying B-grade jade thinking it's real because it looks good and is cheaper. But in reality, B-grade jade lacks the durability and authenticity of true jade. It doesn’t meet the three key qualities of jewelry—beauty, rarity, and longevity—and therefore cannot be considered real jade. B+C Bracelet C-grade jade is artificially colored jade. This involves adding synthetic colors to naturally colorless jade, usually through heat treatment to open up micro-cracks, allowing dyes to penetrate. The resulting colors are often unnatural, appearing as if they're concentrated along the cracks, resembling capillaries. These dyed colors lack depth and seem flat or "dead," unlike the vibrant, natural hues found in A-grade jade. B-grade Safety Buckle While professional appraisers can easily distinguish B and C-grade jade, there’s no simple trick for the average person. Some suggest using hair to test the jade, but this method is not scientifically valid and can lead to mistakes. Experts recommend looking at the color distribution under light—B-grade jade often shows color along cracks, while C-grade jade may have uneven or unnatural coloring. Additionally, B-grade jade tends to have a waxy luster, whereas A-grade jade has a bright, glassy sheen. If you tap a jade bracelet with another piece of jade or a coin, A-grade will sound crisp and clear, while B-grade sounds dull and lifeless.
