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.
Diamond Jewellery and diamond shapes
Study the variety of diamond shapes online to see which one you like most. Make sure you understand the difference between karats and carats before shopping for diamonds. Cubic zirconium looks like a real diamond, but is not. A karat measures the purity of gold. 24k is the purest gold.
A carat measures fine gemstones and the weight of diamonds. Each has its own unique brilliance. Larger diamonds, such as those on diamond engagement rings, will usually carry a greater weight in carats than smaller stones, such as those found in diamond tennis bracelets. Look for diamond fine jewelry in which the diamond itself has a carat weight. Diamonds may be round brilliant, oval, tiffany, marquise, pear-shaped, heart-shaped, cushion cut , emerald cut, trilliant, radiant, or princess cut. Make sure the diamond is not cubic zirconium.
Silver jewellery should be given extra care
Silver jewellery is not expensive. Silver Jewellery has a textured or satin finish so it should be given more care. Do not keep them in contact with oxidized Jewellery, pearls or absorbent stones. Before packing donít forget to dry your wet jewellery. The finishes are achieved with lots of care and it should be maintained accordingly. With clean soft cloth polish your jewellery.
To keep the jewels tarnish free, you can use silica gel packs to keep dry, do not always use body scents on them directly. You can also soak them in warm soap water and use a soft bristled brush. Often a green or black residue is formed on large silver jewels due to the bodyís chemicals. But they can be cleaned easily. Remember to wear your silver Jewellery as much as possible because Wearing them actually keeps them polished and less tarnished. A rinse-off liquid cleaner is best for tarnish to clean your ornaments.
