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.
A gemstone is a stone that is beautiful
A gemstone is a stone that is beautiful, rare, and durable resistant to abrasion. Today, finer gemstone specimens are available to the average person than at any time in history.
Nowadays such a distinction is no longer made by the trade. Rare or unusual gemstones, generally meant to include those gemstones which occur so infrequently in gem quality that they are scarcely known except to connoisseurs, include andalusite, cassiterite and bixbite. Some minerals can be very beautiful, but they may be too soft and will scratch easily (such as the mineral fluorite). Fluorite is extremely colorful and pretty but has a hardness of only 4 on the hardness scale and has four perfect cleavage directions, which makes it only an oddity as a cut gem.
Silver is always in fashion
Because silver jewellery is trendy and simple it has been always in fashion. Sterling silver can be enjoyed a life time. It being a precious metal it is more affordable than gold and platinum. Always keep your ornaments separately, preferably in a cloth pouch or jewellery box in order to prevent scratching and tarnishing. When silver reacts with sulfur or hydrogen sulfide in the ambient air its normal for silver to tarnish.
To make silver ornaments last a life time you must have to follow simple steps. It can be easily removed by polishing with cloth or solutions specifically formulated for silver cleaning, which can be found in any hardware store. Always avoid exposing it to household chemicals, such as bleach or chlorinated water.
