I have my 14mm amar slide for sale, I’ve owned this slide for almost a year now, has been taken care of well and I would give it an 9/10 due to it being used but cleaned very very often and having no stains, water marks, chips or scratches. If you would like more photos shoot me a DM and I will be happy to. 
This slide features an opal on the side, a crushed opal section on the mid section, green joint, and a green/purple spiral worked section on the upper section. Medium size pack.
