Yellow crystal has the color characteristic of regal nobility, symbolizing the light of wealth, and at the same time, yellow crystal is more glittering and translucent get rid of transparent than yellow jade crystal, so it is favored by consumers. The criteria for evaluating crystals are different from those for high-end gems. Most high-end gems rank color first in their evaluation, and for crystals, color and clarity (the crystal industry calls them crystals) are almost as important.


The evaluation criteria of topaz

1. Color: color is very important for any gem, and crystal is no exception. If the crystal crystal is colored, such as pink crystal, yellow crystal, amethyst, etc., the highest standard of color evaluation is bright and attractive, not with gray, black, brown and other colors. For example, pink is the best color. Amethyst, requires a deep purple micro with flame light color, transparent without cotton wadding; Yellow crystal, requirement color does not contain green, lemon tonal, with golden orange color is better.


2. Clarity: the clarity requirements of topaz and high-grade stones are very different. High-grade stones are rare and rare, so the general public is not too strict on the cleanliness of high-grade stones. The amount of topaz produced is truly staggering, so it is usually required to keep the topaz as clean as possible and to avoid topaz with obvious inclusions.


3. Impurities: if the impurities inside the yellow crystal contain the shapes of characters in legend, such as Buddha, constellation, zodiac, etc., the value may be higher than the crystal of the same color and clarity.
