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.

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.
