Wood is the material that interests me the most out of the three, so I decided to look into wooden jewellery - something completely new to me, and this is what I found:
Katy Hackney is a London based jeweller who uses wood and other non-traditional materials in her work
Julia Harrison is a US based jeweller who works in wood - her face brooches are amazing! Here is her blog
Grace Girvan - A Scottish jeweller who uses wood and pebbles. Now that's exciting!
The London Jewellery School run Wood Carved Jewellery classes - so it must be popular!
So many lovely things that people make, so many different approaches to using wood in jewellery... I just need to come up with something completely different :-)
