To transform the diamond into a beautiful gem, it is cut with precise facets. Well cut diamonds have amazing brilliance and fire. This is caused by light reflecting off the diamond's surfaces. The key to desirable fire and brilliance is proportion. Light striking a shallow cut diamond or a diamond cut too deep is lost through the sides or bottom and is not reflected back to the top. Of all the cuts, the perfectly sparkling round brilliant cut is the most popular diamond shape, but there are many others to choose from, including the classic emerald cut, with its clean lines and sophisticated shape, or the elegant ovals or cushion cuts.
While many diamonds appear colourless or white, they may actually have subtle yellow or brown tones that can be detected when comparing diamonds side by side. Colourless diamonds are the rarest and most valuable of all.
Clarity of diamonds. Clarity is an indication of a diamond's purity, determined by naturally occuring internal characteristics called inclusions. These characteristics are sometimes not visible to the naked eye and they are what make each diamond unique.
Diamonds are measured in terms of weight, not size. One carat is equal to 100 points. Two diamonds of equal weight can have different values, because the quality is still determined by the colour, clarity and cut.
Care of Diamonds
While diamonds are extremely hard, they can still suffer chips and fractures from sharp blows to the stone. Naturally, you should always try to protect your jewellery from sharp blows. Diamonds are also extremely scratch-resistant, however it is possible to scratch a diamond with another diamond, so care must always be taken to ensure that stones do not knock each other when worn or stored together.
To keep your diamond jewellery looking sparkling and brilliant, we advise regular cleaning. We offer a complimentary cleaning service to all our customers. Should you wish to clean your jewellery at home we always recommend to our customers that they use only a soft bristled toothbrush and warm water with washing up liquid, then rinse and gently dry the jewellery with a soft cloth.
An expression of integrity, platinum's purity endows it with a brilliant white lustre. Platinum is generally 95% pure, so platinum jewellery will not fade or tarnish and is kind to the skin. (It is very rare to have an allergic reaction to platinum). Platinum's unequaled durability, density and resistance to wear makes it the most secure, protective metal for settings, which means your jewellery will be protected for a lifetime of wear. As platinum is naturally silvery white in appearance, it does not require rhodium plating like white gold. Platinum is purer and rarer than white gold and it retains its whiteness better than white gold. Platinum does not wear away and holds precious stones securely.
As it is an extremely hard metai it is an ideal setting for diamonds and gemstones. This does not stop it from scratching when worn as a ring, which will occur with normal wear and tear and like gold, it will eventually acquire its own surface patina.
The hardness of platinum whilst being an attribute makes it very difficult to work with from the jewellers perspective, and many more hours go into making and finishing a platinum piece of jewellery than one in any other precious metal.
18ct White Gold
18ct White Gold has a slight natural yellow tint. It is normal practice to finish white gold items with a rhodium plating which renders the piece 'silver' white. Items such as earrings, pendants, bracelets and necklaces do not suffer the wear and tear that rings do and as a consequence rings in white gold will show signs of the underlying yellow tint after a period of wear. This can easily be rectified with a re-polish and new rhodium plating.
Rings with large plain surfaces are more prone to this than others with a detailed surface. We always recommend that rings are removed when gardening or doing work which could cause them to get knocked or scratched.
