Like gold, platinum is ideal for setting your diamonds and gemstones. However, to enjoy it to the full, make sure to keep it clean and safe.

While it is the strongest of metals, it can scratch and develop a lustre of wear. Many people prefer this look, but if you like it to be shiney like new then a good jeweller can polish it back to the original high polish.

Do not wear your platinum jewellery during rough work or handling household chemicals. Keep it in a jewellery box away from other pieces so that it does not get scratched. Also regularly check the settings and if any claws seem loose then immediately take it along to a professional for attention.
