About the proper care of precious stones
Everyone loves their precious stones, their colors and beauty, offering the attractiveness and elegance of those who wear them. Although they have been used in the manufacture of jewelery for thousands of years, few are those who know the details of proper care for them. Some simple tips can allow their preservation over time.
1. Gemstones and semiprecious stones are natural crystals. Depending on the hardness minerals it may have different levels of resistance, so it is necessary to be protected from shocks or blows. Excepting diamond that is a very hard mineral, all others can be affected: flaws, cracks, scratches, etc. Over the last 20 years, various treatments have gone on, ranging from heating or even melting the crystal at the molecular level to resin inserts, special glass, beryllium diffusion, chemical dyeing, etc. Thus even crystals that are apparently very solid can provide surprises. Once the stone has been affected, in most cases nothing can be done. Precious and semiprecious gemstones sensitive to strikes are: rubies and sapphires treated by special glass insertion, kunzite and apatite due to cleavage (the predisposition of the mineral to split on a natural preset line), aquamarine, beryllium, emerald, tourmaline, chrome diopside and kyanite through the natural presence of internal fractures. In the case of emeralds, polymer treatments or cedar oil lubrication make them vulnerable to external mechanical or chemical exposure.
2. X-ray irradiated stones such as London, Sky or Swiss topaz can be affected by the prolonged presence of heat or by strong sunlight. Thus their abandonment under sunlight windows or natural environment for a long time may result in their discoloration. The same process can occur if it are left on the stoves, heating for a long time. Issues related to exposure to high temperatures include rubies, sapphires or emeralds whose cracks have been filled with special glass. When precious stones are mounted, jewelers must avoid working with fire, exposing them to high temperatures. The stones will only be mounted after the jewelery has been finished.
3 Gemstones and semiprecious stones are sensitive to chemicals and can be affected by different types of reactions or corrosion. In the case of berilium-treated stones, oxides or other color-enhancing substances, their contact with solvents may cause loss of gloss and even it color change or blur. Jewelry with precious stones must not be worn when washing laundry or cooking utensils, during food preparation or household cleaning. Emeralds cedar oiled, sapphires and rubies treated by insertion of special glass will become clorless or faded once it exposed to corrosive substances or solvents. Cleaning jewels, after finishing with chemicals by jewelers, can lead to altering the appearance of precious stones.
4. In the case of opal, it is recommended to keep it in tightly closed containers to avoid drying. Periodically it is advisable to put a small piece of cotton wool with water in the jewelry pocket. The opals need moisture to keep their shine and coloring.
5. A modern method for cleaning jewelery is by ultrasound but precautions should be taken depending on the type and condition of the mineral in order to avoid fracturing of the crystals or amplification of existing fractures.
6. The best method of care and cleaning of precious stones or jewels containing them is under warm water jet, with very little soap if necessary and a soft brush to remove dirt under or next to the mounts. Drying is done with a soft cotton cloth. Human skin permanently secretes fat and this causes the dirt of jewelry which makes it necessary to clean them regularly.
I hope this information will help you to enjoy your jewelry for a long time.
