Palladium

Palladium

This is a lustrous, malleable and ductile rare transition metal from the platinum family together with Rhodium. Chemically, all three are very similar, and is usually extracted from either copper or nickel, without the allergy reactions sometimes associated with nickel. Here’s the science bit – its symbol is Pd and its atomic number is 46. It has two main uses, firstly as a component in jewelry and secondly as a catalyst in industrial manufacturing and is a good purifier of Hydrogen. It was discovered by the well known Professor W.H. Wollaston in London. It is found in the rich platinum and other precious and semi-precious deposits in the former U.S.S.R. and from copper/nickel deposits in America, Australia and South Africa. It no known biological role, is non toxic (hence being used in jewellery), resists corrosion and rusting but reacts with oxidising acids and alkalis.

Palladium Wedding rings

The latest fashion and one of the hottest selling white metal products through the Internet seems to be palladium wedding rings. It is hypoallergenic, is more precious than gold, whiter than white gold, never needs to be rhodium plated and is as white as platinum and slightly less expensive. In the long term, although it is more precious than white gold, it will work our cheaper as it will not need visits to the goldsmith every twelve to eighteen months for plating or dipping. Jewellers have been looking for something for many years, as it is non allergic and needs very little care, making it a perfect cost effective alternative to the more expensive platinum. A good industry standard alloy mix you should look for is ninety five percent Palladium and five percent ruthenium, which is also an alloy from the same family. This combination is technically known as PD950 or 950Palladium. At the moment this precious metal is relatively unknown commercially, but because it is from the same family as Platinum, Palladium wedding bands or engagement rings share the same properties; both are naturally white metals, non tarnish, hypoallergenic and strong. Palladium also looks good combined with a diamond to make a diamond wedding ring.

Palladium engagement rings

The physical weight is very similar to that of 14 karat white gold and one advantage is that if you require the date or place of the engagement engraving, Palladium engagement rings will not discolour or tarnish on the outer layer and will never need dipping or surface renewal with the rhodium plating. As an engagement band, it will be thirty to forty percent lighter than Platinum, making it slightly less expensive to buy, but is equally as white and as tarnish free. Its high durability will make it out last normal gold and due to recent high demand of platinum, it really is a good alternative as an engagement ring or wedding band. It does pay to shop around a little when looking for this type of ring, as different jewellery outlets and designers use different qualities when it comes to adding Ruthenium, so please do check the alloy mix.
