Process of Casting silver Jewellery
A two-step process, investment casting, produces small, complex shapes. Most castings, especially large ones, are made in sand molds. Permanent metal molds are used to make many small, simple parts; shell molding gives greater accuracy for a large volume of semi precision parts.
Molten silver is poured into the cavity and allowed to solidify. Sand, mixed with a binder to hold it together, is pressed around a wooden pattern that leaves a cavity in the sand. Wax or plastic replicas of the parts are molded in accurate metal molds. Top of the line casting equipments are utilized to produce the silver jewellery. When the whole mold is heated, the replica melts, leaving behind a cavity into which silver is poured.

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.
