Maintenance method of turquoise

Turquoise, like other precious things, needs to be cherished and maintained, otherwise it will change from clean to dirty, from bright to dark, and from new to old during use. Most turquoise has holes, which can absorb hand oil, lip balm and perfume. Although in the traditional process of our country, the surface of turquoise is coated with a layer of paraffin, which increases the color of turquoise and also plays a role in protecting turquoise.

Pay attention to sweat stains, oil stains, etc. when wearing. Avoid excessive contact with cosmetics and skin oil, so as not to damage the gem. Because turquoise is porous, attention should be paid to avoid using heavy liquid to measure density, because tribromomethane and diiodomethane will discolor turquoise. Turquoise is delicate in color and afraid of pollution. Contact with tea, soapy water, oil stain, rust and alcohol should be avoided to prevent them from infiltrating into pores and discoloring gems.

Turquoise is afraid of high temperature, so it can't be baked directly and exposed to direct sunlight to avoid fading, cracking and drying. Exposure to the sun for a long time will make turquoise crack and discolor due to water loss, and baking at too high a temperature will make turquoise brittle. Some Indian handmade jewelry is exquisitely made and expensive to repair.

Turquoise is not very hard, so you should avoid colliding with other jewelry or articles with high hardness when wearing and storing it. Don't put turquoise in the ultrasonic cleaner. On the one hand, porous turquoise will absorb the solution and make it fade. On the other hand, turquoise with holes or dense surface may be damaged by contact with other gems during ultrasonic vibration.
