Gold & Platinum



Gold is graded not by weight, but by purity called Karats. Pure Gold is 24K, but is too soft for use in jewellery. The best purity of gold for jewellery is 18K, or 75% pure gold and 25% alloy. This is what we always use at Jason Withers Original Diamonds, as it ensures excellent wearability and a fabulous colour.

Jason always considers Gold trade-ins as a partial form of payment for a design. If you have Gold jewellery no longer in use, feel welcome to bring it into your appointment to discuss your options. 85% of Gold used in the ancient past is still being used in jewellery and other products today! palladium

White gold is a very popular choice for jewellery. Jason Withers 18K White Gold is alloyed with Palladium, which unlike nickle and zinc (commonly used by many jewellers) is a very rare, precious metal in the Platinum family that does not tarnish or discolour. This ensures a longer life and a whiter, brighter finish.

Our White Gold is finished with a final plating of Rhodium, one of the rarest metals on Earth. This enhances the shiny, bright white finish that attracts so many people to White Gold. When buying a wedding band and engagement ring set, it is imperative that both rings be made of the same metal. If one is Platinum and the other White Gold, the Platinum will rapidly deteriorate the White Gold because of their different densities and durability.

Platinum is a silvery-white, precious metal which when alloyed to correct standards is more expensive than gold, due to it's extreme rarity and manufacturing difficulties. Unlike the best gold, which with constant wear has a lifespan of about forty years; platinum is much harder and more durable and lasts for three lifetimes. Jason Withers only uses the best, with 95% platinum and 5% Ruthenium alloy, a precious metal in the same family. Platinum of this grade is stamped with "PLAT".



Titanium is an option some men consider when looking into purchasing wedding bands. There are several points to consider when thinking about titanium as your choice of metal. Jason Withers uses aircraft-grade titanium which is known for its extreme durability, lightness and the favourable characteristic that it never discolours. Titanium can be finished as a "brushed" or "polished" look, or a mixture of both. However, once made, a titanium ring cannot be resized. Jason will always inform you of everything you need to know before making a decision on a setting.
