How to cover up the mineral spots on turquoise?

Mineral spots on turquoise are one of the defects of natural turquoise, and there are also white spots and cracks, which are natural phenomena of natural minerals. Artificial processing, such as wax dipping, glue dipping, glue pouring and dyeing, can increase the appearance and cover up some defects, but such turquoise is no longer natural turquoise, but optimized turquoise.

The following is an introduction to the identification method of optimized processing without the identifier:

A. Water measurement method: Generally, the inlaid turquoise is polished on the front, but not on the back. Turquoise can be soaked in clear water, and the untreated water will be absorbed immediately, while the absorption by soaking in wax and glue will be slow, and the one filled with glue will not be absorbed at all.

Putting untreated turquoise into water will darken its color, while treated turquoise will not change, so turquoise without any optimization treatment is very sensitive to weather changes. Turquoise darkens when it rains on cloudy days, and becomes shallow when it is dry. Similarly, the same turquoise will be darker in the south than in the north. The rainy season is deeper than the dry season, and it will be darker when worn for a while than when mined.

B. Visual inspection method: the surface without optimization treatment is often uneven (especially with more patterns), and the optimized surface is very smooth.

Many people like smooth surfaces and have no hobbies. In fact, most of them are smooth, especially those with patterns. )

No optimization treatment-ceramic luster (inlay: the unpolished side is the original state of the ore, without luster).

Wax dipping-waxy luster,

Dip in glue luster (especially inlaid, the unpolished side has obvious glue luster),

Glue pouring-black hair, poor luster (for inlay, the unpolished side is completely cured colloidal luster).

C, different characteristics: after a long time of optimization, it will become dark but not fragile, but without optimization, it will become better and brighter.

Unreoptimized turquoise: expensive, but very valuable (the price is rising this year), with good luster, the brighter you wear it.

The price of optimization treatment is cheap and not fragile, but the gloss is not good, and the more it passes through, the less luster it has. In addition to waxing, other optimization methods are optimized, which has little collection value and is more suitable for processing into decorations because of its low price.
