From the texture point of view: high-quality yellow wax stone has fine texture and strong wax texture. When illuminated by a strong flashlight, it has good transparency and very soft refraction, and no crystal particles can be seen by naked eyes.
From the color point of view: pure yellow is the top grade, bright color is the best, and the brighter, purer and rarer the color, the more top grade it is.
From the modeling point of view: if the modeling is unique, the lines are delicate and have unique charm, then the value must be high.
Judging from the grain size and texture of the polished surface, there are no emeralds (or Philippe) and microwave lines on the polished surface of high-quality Huang Longyu because the particles are too small to be seen by naked eyes, while topaz has emeralds (or Philippe) and microwave lines.
From the weight point of view, the density of yellow wax stone is different from that of Huang Fei, the former is 2.60 and the latter is 3.33, which makes yellow wax stone obviously lighter than yellow jade.
Extended data:
Xanthite can be confused with yellow jadeite, and its color, texture and hardness are strikingly similar to topaz (yellow jadeite) in natural jadeite, so that when it first entered the market, many consumers and jewelers mistook it for yellow jadeite, and some careless inspection departments even identified it as a mistake of yellow jadeite. The nondestructive identification method of the two is mainly based on their obvious differences in mineral granularity, density, refractive index, polished surface texture and distribution characteristics under high magnification.
According to the texture. The texture of yellow wax stone is generally smooth and delicate, so its authenticity and grade can be identified by observing its compactness, fineness, transmittance and softness of radiation light. Generally speaking, the yellow wax stone has no daunting wildness, only the gentleness and aura that overflows the surface and is accepted by the heart.
Identify by color. Yellow is the most expensive color of yellow wax stone, and the brighter the color, the more favored by collectors. Generally speaking, pure bright yellow is the best, and wax yellow, khaki yellow, chicken oil yellow, egg yolk, ivory yellow and orange are slightly less.
According to the special shape. Generally, the shapes of yellow wax stones are peculiar and diverse. If we can clearly see what it constitutes, and the color is just the same, it has a high collection value. More common like some animals, such as monkeys, tigers, rabbits.
