About Me

My name is Isaac Mayes  I make and design everything under ONYX.925

Everything is created by hand from start to finish. All pieces are made from solid silver or 9ct gold. 

The reason I got hooked on making jewellery is, it allows me to live the lifestyle I want. I can surf when there are waves, go to the beach when it’s sunny and make jewellery inbetween.


Once again, outstanding job on the pendant and chain, couldn't be happier! I'm genuinely over the moon!

Isaac, my buddy was properly blown away by his dog tag. He was actually speechless. Job done. Thank you so much again.

The rings are ace! Size fits spot on, quality looks perfect and they are just so lovely
