View MoreTo ensure the thickness and uniformity of the coating layer, a number of factors need to be considered, including selecting the appropriate coating process, optimizing the coating parameters, optimizing the substrate and target pretreatment, using advanced coating equipment and technology, and strengthening the monitoring and testing of the coating process. Through the implementation of these measures, the coating layer with high quality and good uniformity can be obtained.
View MoreBy observing the clarity, transparency grading, internal characteristics and performance under light exposure, the quality of the emerald can be preliminarily judged. The higher the transparency, the fewer internal features, and the better the emeralds perform in light, the higher the quality is generally.
View MoreThe key to dealing with concerns about emerald staining or coating is to use professional equipment for testing, to observe color distribution and uniformity, to check the absorption spectrum of the gemstone, to ask and look at certificates, and to buy carefully and consult experts. Through these methods, consumers can more accurately judge the authenticity and quality of emeralds, to avoid unnecessary losses.
View MoreThe color judgment of emerald identification needs to observe the purity, hue and saturation, and compare and reference under natural light. At the same time, be wary of manual processing, combined with comprehensive assessment of transparency.
View MoreAlthough weight can be used as a reference factor to distinguish the authenticity of emeralds, it cannot be used as a judgment basis alone. In the process of identification, it is necessary to use a variety of methods and treat any abnormal phenomenon with caution.
View MoreThe above methods can help you initially identify the true and false emeralds, but to ensure accuracy, it is recommended to use a combination of methods and seek professional identification.
View MoreThe coating effect of resin lens is affected by many factors such as coating technology, coating material, coating thickness, lens material, post-coating treatment and use environment.
View MoreThrough the above measures, the problem of resin lenses easily reflecting light can be significantly improved, and the visual experience of the wearer can be improved.
View MoreIt should be noted that although resin lenses can improve their UV protection through the above measures, their effect may still be affected by a variety of factors such as lens material, thickness, coating quality and the environment in which they are used. Therefore, in the purchase and use of resin lenses, consumers should consider various factors, and choose a lens with good UV protection performance.
