Purchasing high quality hand made jewellery can sometimes be a tricky and confusing business! Read below some of the frequently asked questions about the jewellery making process, the end product and delivery to you. For any further questions please contact

Kate McCoy is a qualified diamond grader (IGI), gemologist (GII) and jewellery designer based in Sydney, Australia. Kate creates high fashion and bespoke jewellery for women and men. Her pieces are uniquely designed and hand made to the highest quality.



What materials do you use to make your jewellery?

All fashion jewellery pieces are made from sterling silver (unless stated otherwise). Selected products are then plated in 14kt yellow gold, 14kt rose gold or rhodium. Kate McCoy currently uses a range of authentic gemstones, hand picked, such as; rose quartz, black onyx, lace agate, lapis lazuli, amethyst, garnet, aquamarine, turquoise, carnelian, citrine, smoky quartz, apple quartz, sunstone, hydrothermal emerald, hydrothermal ruby, pearl and more. 

Most fine jewellery pieces are made from 9-18kt white, yellow or rose gold and/or platinum. All gemstones used in fine jewellery pieces are hand picked, ensuring the fine quality associated with fine jewellery.

All engagement and wedding rings are bespoke creations, and as such, each piece is unique in design. Rest assured your Kate McCoy design will not be mass produced! Engagement and wedding ring bands are made using a choice from sterling silver, white gold, yellow gold, rose gold or platinum. Stones used in engagement and wedding rings most commonly include, but are not limited to, diamonds, rubies or sapphires. Other stones are available, but it is not recommended if their hardness is below 7 on the moh scale.

Where do you source the metals and gemstones from?

Materials are sourced worldwide, subject to origin and availability. For example, emeralds are unique to Colombia and Zambia, whilst Ink Blue Sapphires and Argyle diamonds are unique to Australia. Most materials are sourced at the International Jewelry Trade Fair in Hong Kong where suppliers from all over the world gather three times a year to trade precious goods. Outside of this, the majority of materials are sourced in Australia. All metals are industry stamped for quality assurance.

How do I care for my jewellery?

Kate McCoy designs and hand makes high quality fashion jewellery that is beautiful and long lasting. However all jewellery is subject to minor scratches and knocks through everyday wear and tear, and must be cared for and looked after. 

  • Do not get your jewellery wet. Jewellery should be removed when washing hands, showering and swimming. (Just don't forget to put it back on!)
  • Remove jewellery when doing rough work such as gardening, cleaning or manual labor. 
  • Keep your jewellery clear of makeup, moisturisers, perfumes and sprays as much as possible. It is best to apply products before putting on jewellery. Harsh chemicals can damage and weaken jewellery and may change the colour (these are bad for the environment anyway - steer clear).
  • Use a soft, clean cloth when polishing jewellery after every wear to maintain the polish of the metal and shine of the gemstone.
  • Store your jewellery in a dry area, out of direct sunlight.
  • Rings will always get the most wear and tear as we use our hands constantly. Unfortunately this is unavoidable. 
  • Silver has a tendency to tarnish over time. A gentle polishing with a soft cloth after wearing, particularly if your jewellery has been in contact with sunscreen, makeup or perspiration, before storing will ensure the next time you take it out to flaunt, it will look amazing!

The great thing about Kate McCoy jewellery is that you can always get any pieces cleaned, re-polished and or re-plated. The cost for having jewellery pieces re-polished or re-plated varies depending upon the size and intricacy of the design. If you would like to have a piece detailed, please send a clear photo and description to to organise an appointment or postage.

How can I find my ring size?

Within Australia, letters are used to indicate ring size. Ring sizes start at I and go up to size Z.

The easiest way to find your ring size is to use a thin strip of paper and wrap it firmly around the finger you wish to wear the ring on. Mark where the end meets and measure against a ruler in millimeters - this will indicate your exact ring size.
