My son has really started to get into faceting. He bought a boule of hydrothermal emerald(man made) as he wanted to cut a design he made specific to emerald.
He sliced the emerald in half and gave me one half while he cut his up into the sizes he was going to facet.
I was mostly hands off with this and only really helped out when his stone popped off the dop. He did a great job!
Cracking job, love the colour
