Rawfiche & Gemstones

Garnet 

Source: Czech Republic & China

I use tiny shards of Raw Garnet (uncut) to add colour and fill small gaps between pieces of seaglass & seapottery

Apatite

Source: Brazil

I use tiny shards of apatite to fill gaps in pieces or add a specific tone to a piece. 

In the example above seaglass is around the top of the thistle and apatite has been used at the bottom.

Labradorite

Source: Scandinavia

I only use a tiny amount of labradorite to add colour or fill gaps, using Scandinavian Labradorite is quite expensive but a little goes a long way!
