B everyone is familiar with the jadeite, and for the poor quality jadeite, it is often used

“Pickled+Charged”

Method for processing. Because emerald belongs to

Polycrystalline collection

, “Pickled+Charged” can remove the impurities between the crystal particles and the cracks, which greatly improves the gem clarity.

Then you know

As a single crystal gemstone sea blue gemstone

Can you also use this method to improve the clarity and color?

By bleaching, have you recruited your sea blue gem bead skewers?

Sea blue gems have seawater -like charming blue, clear and pure, and sweet and sweet. In recent years, it has been favored by consumers.

However, many natural sea blue gems have no color and crack development, so more and more sea sapphires appear in the market.

Sea blue gems with poor clarity and fissure development are often made into beads or carvings. According to relevant scholars’ on -site investigation,

In recent years, the processing of the category gemstone in the Kitang beads in Shanwei, Guangdong has repeatedly carried out the “irrigation” process.

Traditional bead -shaped gem process process

In recent years

Completed from “Characteristics and Appraisal of Breaking Charging Sapphire Sapphire”

There are two main functions of “irrigation”: first, the gemstone can prevent the gemstone from cracking during processing; second, it can cover the cracks and increase the precautions and transparency of gemstones.

According to the national standard GB/T 16552-2017 “Jewelry and Jade Clever”, jewelry and jade filled by bleach belong to the category of treatment. So, how to identify the processed sea blue gems and natural sea blue gems?

01, refractive index and relative density

The refractive index of natural sea sapphires and sea sapphires is basically the same, from 1.57 to 1.58;

Most filled sea sapphire density is slightly lower (less than 2.72g/cm3)

Under the light,

The filled sea blue gemstone can see the “flash effect” in the fissure direction

It is due to the difference in refractive index between the filler and the gemstone, which occurs in the film interference;

03, fluorescent features

Do you think the face -to -face sea blue gem is safe?

Compared with beaded, high -quality sea sapphires that are filled with and filled in are less in the market, but everyone must also be vigilant.

Although the cargo has changed, it also has the “evidence” left by filling the processing processing!

two,

Ultraviolet fluorescence

: Observe at Diamond Viewtm, the filler in the gem fissure emits strong fluorescence.

three,

Infrared spectrum test

: Show an organic substance absorption peak.
