What is Silver?
Sterling silver is 92.5% silver and is sometimes referred to as pure silver. Sterling silver will tarnish over time but with care and regular cleaning can be restored to its good as new sparkling condition. The remaining 7.5% is usually copper but can be other metal and is used to give this precious metal strength and durability.
Generally, the higher the silver content the brighter or whiter the metal but beware of antiquing effects that can make a piece of sterling silver jewellery or decorative silverware look dark. Silver which is 99.9% silver is too soft to be practical for most day to day uses. Do not use tissue or anything other than a jewellery cleaning cloth to polish your jewellery as unseen tiny hard fibers will scratch the surface.
Pearls come in a variety of colors and shapes
A high quality pearl will have a lustrous, shiny surface, strong reflections, and a good contrast between its light and dark areas. Pearls come in a variety of colors. That colors are white, gray, black and yellow. The shapes of pearls can be round, baroque, symmetrical, or irregular. The most exquisite and expensive pearls are the sphere-like round pearls.
But still your pearls should have minimal blemishes on the surface such as pits, cracks, or discoloration. Necklaces with pearls can have single or double strands. The single strands usually have larger, more expensive pearls than the double strands. Pearls that appear completely flawless are usually fakes. Authentic pearl earrings should match in size and their look and feel.
Cleaning is must in gemstone
For stubborn dirt, a soft brush can also be used on these types of stones. In hot environments, the heat can cause the water to evaporate and discolor an opal. Jewellers use mechanical cleaning procedures to clean gemstones. Some of these methods can be harmful if done incorrectly, so ensure that the cleaning is being performed by a qualified professional.
One common method is ultrasonic cleaning, which uses frequency waves to clean gemstones. They can be cleaned in the same mild detergent and water solution as other gemstones, and delicately scrubbed with a very soft brush. Designer jewellery can cover the gamut of rings, engagement and wedding rings, watches, necklaces and pendants, bracelets and anklets, cuff links, tiaras and other unusual pieces.
