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.
Cut of the stone
Firstly we talked about the cut of the stone. Now finding a good quality bright green tourmaline with this cut is not impossible to find but can be tricky so we decided that custom cutting was the way forward. We custom cut the green tourmaline from a larger cushion stone to create the look. We combined the chequer board facetted cut on top but with a more square proportioned shape rather than oval.The lapidaries squared up the proportions and then facetted the top of the stone. This creating a square cushion shape with a facetted top! Donna felt a straight sided square stone would be a little harsh so decided that she would like to have the stone with softened corners. The initial stone was 1.72cts and ended up at 1.05ct. After being cut gemstone it is difficult. We searched for a green tourmaline of the right colour that could be cut to shape. The twist ring is simple in style holds the tourmaline for a modern design.
Buy silver jewellery online
When you buy your jewellery from these online places you really will be saving loads of money by buying these products. At a fraction of the cost is than they would normally sell for. Note that just because these pieces are less money cost wise, doesn't mean they are lower in quality!Obviously some sites online will sell chintzy materials, but this doesn't go for every place out there, you simply have to know where to look and what to look for! 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.
