Hetian Moyu is a rare type of jade, which makes it highly valuable. In some cases, well-crafted pieces of ink jade can even be more expensive than white jade. When identifying genuine ink jade, there are several key factors to consider. First, the color should be a deep, pure black. If it appears dark gray, it may indicate impurities or lack of authenticity. The color distribution must also be even throughout the piece. Uneven coloring might suggest that it's not natural but rather a decorative or imitation work. The second important aspect is the texture of the jade. High-quality ink jade should have a smooth and fine surface, similar to the softness of sheep fat. It should appear as dark as ink, making it a top-tier choice for collectors. The third factor is distinguishing it from common imitations. On the market, you often find fakes made from materials like kava stone, Qinghai jade, or Xinjiang black jasper. Kava stone lacks the oily feel and luster of real jade. Qinghai jade tends to have a lighter tone and may show purple-red spots or white calcified areas under close inspection. Black jasper, when held up to strong light, can reveal greenish hues along its edges. However, since black jasper is still a form of jasper, when evaluating quality, start by checking the depth of blackness and then look for any impurities within the stone. Ink jade is a rare and precious natural resource, with great potential for collectors. Due to its scarcity and high value, it's essential to be cautious during identification to avoid falling for fake products. Always consult an expert or use reliable testing methods before making a purchase.
