Platinum - the most precious metal used in jewellery, is a metal that is lustrous and silvery grey in colour by nature. Platinum is dense, more durable and stronger than Gold. Because of it’s durability, it will assure you that your most precious diamonds and gems will be secure. Platinum does get scratched more easily than Gold, however, a simple buff and polish will make the Platinum jewellery shiny like new. Platinum is unique in the way that the surface does not need to be removed to become shiny again, the surface is burnished to high polish. Platinum develops a patina finish which is often desired by most people and does not require a Rhodium plating to achieve a shiny white appearance. It is a pure hypoallergenic metal so a Platinum allergy is rare. Platinum is affected by harsh chemicals such as household cleaners and chlorine. We recommend removing your jewellery when using chemicals to reduce daily abrasions and prolong the luster of the metals. Store your platinum jewellery in a soft pouch or it’s original box when not worn to protect it from the elements.

Yellow Gold

Pure gold, also known as 24 karat gold is too soft and malleable to be worn as a finished piece of jewellery. For this reason, the process of alloying—mixing other metals with pure 24 karat gold—gives malleable gold more durability and a variance is colour. Gold will develop a film build up of oils from lotions, powders, soaps and natural skin oils which takes away from it's natural patina. Chemicals in the air can also oxidize the yellow gold depending on the karat grade used. Always remove gold jewellery before entering swimming pools or using household cleaners, such as chlorinated water and harsh chemicals which can erode gold jewellery, create abrasions or reduce luster. Keep your precious pieces of gold jewellery in a fabric-lined jewel case, or a jewellery box with compartments or dividers.

White Gold

The properties of white gold, including its colour, depends on its composition. White gold is an alloy of gold and at least one other white metal. Although most people think white gold is a shiny white metal, that color is actually from the rhodium metal plating that is applied to all white gold jewelry. Without the rhodium coating, white gold might appear gray or dull. Over time, the plating will wear away from the white gold and the piece will need to be brought in for a polish and re-plating.


Like their natural hosts, pearls are prone to damage from pollution and rough treatment. Store pearls separately from other jewellery as these soft stones can be easily scratched by harder gemstones or metals. Excessive sun and heat can also damage pearls, dehydrating them. Perfumes, oils, sunscreen etc should be avoided. Wipe pearls gently with a soft cloth after wear to remove any trace residue. Pearls are normally strung on silk and moisture, oils and frequent touching can degrade the integrity of this silk. As a result, regular re-stringing is recommended. Never expose pearls to chlorinated water or any cleaner other than specific pearl cleaner.

Gem set pieces

The choice of gem-stone setting on a piece of jewellery is a security as well as an aesthetic choice. The more the gem-stone is exposed, the more vulnerable the gem is to damage and loosening. An at home ultrasonic cleaner can also loosen gem settings. Repeated rough treatment and wear can loosen all gem settings and you could lose your precious gems. Fine jewellery should be checked at least once a year for wear and the security of settings.

Sterling silver

Sterling silver is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of other metals, usually copper. Because of this, sterling silver will naturally tarnish when exposed to air. Best method of practice to keep your silver jewellery shiny is by storing it in an airtight container or tarnish-protecting cloth bag to help minimize the amount of care necessary. Keep your sterling silver jewellery in a cool, dry place. Polishing cloths are an excellent choice for cleaning your sterling silver jewellery.
