A Guide to Caring for High Jewellery

What is high jewellery?

High jewellery is hard to define, but easy to know when you see it. Like a luxury car or the perfect cup of coffee, it is not always a question of size or spectacle. Instead high jewellery uses the finest quality precious metals and rare stones, paired with superb craftsmanship in artful designs.

Since 1972 our exceptionally talented Perth jewellery designers have been crafting high jewellery with passion. The result is a boutique selection made with rare coloured diamonds, precious stones hand-picked from our selection, and the highest quality precious metals.

Caring for high jewellery: Tips from our Perth jewellery designers

High jewellery is coveted by many and possessed by few. If you are lucky enough to own a piece then it may appreciate in value, or stay in the family for generations. However ensuring the longevity and lustre of your precious pieces means caring for them the right way.

Cleaning white and coloured diamonds

Linneys is known among Perth jewellery designers for our extensive collection of rare coloured diamonds. Coloured stones, especially Argyle pink diamonds used in our designs, are sought after all over the world for their rarity and beauty.

  • Always clean diamonds by hand to avoid damage
  • Handle the stone sparingly as the oil from fingers can dull its shine
  • Clean regularly, once a week or every fortnight
  • Soak in a gentle degreasing solution (a few drops of mild soap in warm water)
  • Clean gently with a soft, new toothbrush
  • Be especially careful with delicate prongs or antique settings
  • Rinse and dry with a clean, soft lint-free cloth

It is important to steer clear of harsh or abrasive chemicals. Chlorine, bleach, toothpaste, and household cleaners can tarnish and scratch the metal. You should also be incredibly careful with ultrasonic cleaners as the vibrations used to clean hard-to-reach places can shake stones loose.

For peace of mind, consult a Perth jeweller at Linneys every 6-12 months to check for signs of damage and wear.


When you’re not wearing your favourite piece of high jewellery, storing in the right conditions will help to retain its beauty and shine.

  • Store at room temperature, away from direct sunlight
  • Use a jewellery box with a soft, lint-free lining
  • Avoid humid areas like the bathroom
  • Ensure no dust can get in to the storage box
  • Store clean jewellery in a clean area
  • Keep diamond jewellery separate from other pieces to avoid scratching

Of course, if the piece is especially valuable (financially or emotionally) then you may consider storing it in a safe or other secure environment.  

Protecting your investment

High jewellery is something to be treasured, adored, and passed down. With the right care and attention, your finest pieces can last many years and appreciate in value – especially Argyle pink diamonds, which are becoming more rare.

It is important to have your Linneys jewellery professionally inspected and cleaned at least annually. Next time you visit our Perth jewellery design showroom, take advantage of the free cleaning service and allow us to check the settings to keep your high jewellery sparkling and radiant.
