silver band ring The style and cut of gems

Zveřejněno na podle Kingjy

Jak se říká, “You can’t make a jade without cutting it”, which fully explains the importance of jewelry style and cut. Gemologists usually design specific styles according to the optical properties of different gems. The incident light is reflected back to the jewelry table to the maximum extent, showing the unique dispersion effect of the gem, and emitting colorful light. Such as the round diamond style with 58 facets and the rectangular emerald style.

Cutting refers to the craftsmanship level of style design, řezání, polishing and molding involved in processing gems into jewelry. The evaluation of cut depends on symmetry, smoothness, degree of man-made damage and the level of material processing. Symmetry refers to the accuracy of the distribution and proportionality of the arrangement and combination of facets. Smoothness refers to the degree of polishing, generally with a 10x magnifying glass, there can be no traces of polished stripes; man-made damage refers to the operator caused by the processing process, the construction level of the material refers to the elimination or concealment of the raw material defects, or the full display of the raw material advantage. Jak se říká, “three parts of materials and seven parts of labor”, gems can only fully reflect its beauty after careful cutting and polishing. The key to my country’s jade carving crafts is their lifelike shape and exquisite craftsmanship.

The quality and value of the same gemstone are undoubtedly different. Proto, in the economic evaluation of gemstones, its quality is an important evaluation basis. The quality of a gemstone depends on its color, průhlednost, clarity and special optical properties, especially the color and clarity. Například, the value of diamonds of different color grades and different degrees of clarity varies greatly; the value of rubies with pigeon blood red is much higher than that of rose red; the value of jade bracelets with good color and high transparency can reach several million yuan, and the color and transparency The difference is only worth tens or hundreds of yuan.
