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.
Care for Antique Gemstones
Gemstones are a valuable part of any piece of antique jewellery. Common sense is the best preventative measure when caring for any antique gemstone. Although the metal components of ornaments often receive the most attention, gemstone care is equally as important.
Hairdryers should never be used to dry freshly-cleaned gemstones, and no pieces should ever come in contact with chlorine. It is crucial to protect antique jewellery as a whole, in order to maintain as much value as possible over time.
Diamonds are in many colors
The color range of diamonds is amazing and has all the shades from light pink to deep pink, yellow to brown, indigo to dark purple, hues of green and blue. In the past, the brown diamonds were considered to be of lesser value than the other colors because jewellers did not think that consumers would find them attractive. If you are interested in buying your first diamond, you have joined the millions of people who appreciate the beauty of this beloved gemstone.
While diamonds exist in every imaginable color, some colors are more common than others. However, thanks to a few clever designers, brown diamonds are currently one of the most popular trends in the jewelry industry. One of the reasons why brown diamonds are so popular is that they will coordinate with almost any type of outfit. They are also elegant enough to be worn with eveningwear, and casual enough to go with a pair of blue jeans. The blue diamond is another popular variety. As a result, they have a much higher price than the brown and yellow variants.
