What is the heat treatment and optimization of Romania custom engraved bracelets gemstones

’' te gönderildi Kingjy tarafından

But pay special attention: no color-causing substances are added during the heating process. The general industry refers to this method as “first burn”. Örneğin, the green corundum produced in the Macachar mining area in Thailand turns into yellow gemstones when heated; and the Thais accidentally discovered that the originally worthless Sri Lankan milk stone (milk white corundum) contains rutile, which can change from milky white to milky white after heating. Blue becomes Sri Lankan sapphire. Once the color is changed, the gem will maintain a chemical balance, and there is no need to worry about the color recovery or lightening.

Ek olarak, there is the so-called second burn. What is a second degree fever?

Second-degree firing is not heating twice, but adding titanium oxide or iron oxide to lighter natural red sapphire or colorless corundum to become sapphire. Add chromium oxide to become ruby. This method of adding foreign objects to change the appearance of gemstones is called Diffusion Treated by the industry and academically called Diffusion Treated. The price of red and blue treasures that have been burnt twice is one-fifth or one-tenth of natural red and blue treasures.

Ek olarak, many African rubies (opaque, with many cracks) will add glass or silicon to fill the cracks. Special attention should be paid to gemstones processed by this technology. They cannot be directly electroplated when inlaid because of the acid-base effect. The high temperature of electroplating will also melt the filled glass and silicone. Bu arada, it is recommended not to electroplating directly for some gems with soft hardness or high haircut and cracks, such as spodumene, cordierite, kyanite, vesaire., to avoid damage to the gems and cause consumption disputes.

Şu anda, heat treatment has been accepted by gem manufacturers and appraisers all over the world, and consumers can choose to buy heat-treated gemstones with confidence.

In order to make the best use of the material, the general industry will not give up the gemstone because it is lighter in color, uneven in color, or colorless, but will do everything possible to make it more beautiful and look better. This method is similar to a human cosmetic surgery procedure, which is called “optimization treatment”.

There are two main ways to optimize the treatment: one is to add color to the outside of the natural gem to make it more uniform, brighter, darker or change the color; the other is to treat the cracks or dark inclusions in the natural gem with a special laser treatment Remove or fill the cracks in the gemstone with glass or silicone.

Heat treatment or optimization treatments are for natural gemstones and are carried out without changing their essence. Öyleyse, these methods do not affect their natural properties. In identification, it is also natural. This distinguishes heating and optimization processing from fraud.
