Glass bangles are mostly produced in only one Indian city called Firozabad in North India. Bangles that were made from plastic started replacing the glass bangles. Glass bangles are usually smooth, with some texture or set with stones.
However, in many cultures, especially in the Arabian Peninsula and in South Asia, bangles have evolved into various types in which different ones are used at different occasions. In India, Hyderabad has a historic market for bangles named the Laad Bazaar. In Pakistan, glass bangles are almost all produced in Hyderabad, Pakistan. Glass bangles are found in many colors.
Cleaning is must in gemstone
For stubborn dirt, a soft brush can also be used on these types of stones. In hot environments, the heat can cause the water to evaporate and discolor an opal. Jewellers use mechanical cleaning procedures to clean gemstones. Some of these methods can be harmful if done incorrectly, so ensure that the cleaning is being performed by a qualified professional.
One common method is ultrasonic cleaning, which uses frequency waves to clean gemstones. They can be cleaned in the same mild detergent and water solution as other gemstones, and delicately scrubbed with a very soft brush. Designer jewellery can cover the gamut of rings, engagement and wedding rings, watches, necklaces and pendants, bracelets and anklets, cuff links, tiaras and other unusual pieces.
How to care Gemstone?
To remove any detergent, rinse the stone in the same temperature water as the soaking solution. This type of stone can be strung on silk or nylon thread, the silk being a better choice because it fails to accumulate as much dirt as nylon. For diamonds, sapphires, and rubies, bring an equal mixture of household cleaner and water to a boil.
Opals contain almost one-third water and are therefore particularly vulnerable to even moderate temperature changes. Remove from heat and allow the gemstones to soak in the solution until it cools. Thermal shock happens when a stone is instantly transported from one extreme temperature to another. They are all nature's gifts to us. There are more than 40 popular gem varieties and many rarer collector gemstones.
