Sizing & Care Guide

Finding your ring size should be easy!

To find your size... simply grab a ruler, measure the diameter (one side to the other) of an existing ring and match it to the chart below.


Standard sizes we stock are:

Small - 5.5 (K) - Approx 16.20 mm in diameter

Medium - 7 (N 1/2) - Approx 17.30 mm in diameter (most popular women's size) 

Large -  8 (P 1/2) - Approx 18.20 mm in diameter 

If you would like a different size or any men's sizes please email us: Hello@flashjewellery.co.nz 


All Flash is handmade in our New Zealand/Australian studio or ethically via our manufacturer in India. This means every piece is unique and delicate - never two pieces are the same.

We use high-quality metals including sterling silver and semi-precious gems. All gold jewellery is made of brass, then plated heavily in 2.5 microns of 18k gold or is gold filled.

Make that luster last longer by loving and caring for your Flash...
Protecting it from water, (especially salt water) chemicals and objects that can cause scratches or dents. Hairspray, perfume and nail polish will also harm your jewels.

Take your jewellery off when you wash your hands, shower, go swimming, or... If you are left to do the dishes. Gutted.

Please note that all metals naturally tarnish, fade and oxidise with time and will require maintenance.

  • Clean gold plated items soft cloth and mild detergent. Do not use silver polish or strong metal cleaners on gold, It’s too precious for that carry-on!  
  • Sterling silver jewellery is best cleaned with a professional product, follow the manufacturer instructions carefully. Look after gemstones, these are delicate and may chip if not worn carefully.
  • Moisture and humidity can cause oxidisation and tarnishing, so make sure you store your jewellery in a cool, dry place out of sunlight.
  • And lastly, enjoy wearing that Flash!
