Platinum is widely in jewellery manufacture, as it is the hardest of the jewellery metals.
Yellow and Rose Gold are very popular choices for engagement rings, their warm tones work beautifully on the skin and provide a beautiful, rich setting for diamonds and many other gemstones showcasing their beauty in engagement rings, earrings, pendants and other jewellery pieces.
White Gold, which is also mixed with alloys and to many people looks a lot like Platinum, is often used to accentuate the whiteness of diamonds.
It has a warmer white shine than platinum and is also preferred to it in jewellery with an intricate or vintage design.
