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.
Gemstone is desirable for its beauty
A gemstone is the naturally occurring crystalline form of a mineral. Gemstone is desirable for its beauty. It is valuable in rarity. A gemstone or gem also called a precious or semi-precious stone is a piece of attractive mineral, when cut and polished it is used to make jewellery or other adornments. Although some gemstone varieties have been treasured since before history began and others were only discovered recently.Gemstone is durable enough to be enjoyed for generations. However certain rocks, such as lapis-lazuli and organic materials are not minerals, but are still used for jewelry, and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone.

There is no such thing as high quality or low quality sterling, because sterling simply put is the best there is! The overall weight unit of the sterling silver applied in the piece should be the determining component in the cost, unless the item was hand-made, in which case it will cost substantially more than similar pieces that were not handmade.
