Each type of stone or metal ore will have different names and qualities, so to determine its value, it is necessary to analyze the quality of natural gemstones or gem ore quality assess through samples. Natural stone or metal ore mines always have the composition of essences and impurities, the percentage of volume and essence, the higher their commercial value.

In addition, there are many other criteria to evaluate the quality such as

• Purity

• Moh

• Clarity cherateristics

• Shap and Cutting style

• Dimensions

• Colors

• Symmetry

• flourescence

• Weight

• Cut Grade

• Polishing

• Skill

• Many other factors (rarity; history of origin; optical effects;…

Unique quality

• High unit value

The next stages, incl

Cutting, polishing and treating (such as heating, waxing or dyeing), increase the average market price of gemstones by about 50 percent. The production of gemstones together with other materials into jewelry increases the value of the product.

Diverse agents are involved in gem processing and jewelry production, includes large retailers, small and medium-sized companies, and artisans

.

Asia cheaper than!?

The production center is increasingly dominant in the jewelry production and jewelry industry, with

• India handles up to 90% of the global diamond supply
• Gemstones Color processing in Thailand, China (usually Guangzhou), Sri Lanka
