Green wax is for cabbing and has a lower melt temperature, use a good brown faceting wax like Leeco from Graves or other suppliers. Diamond dop is another good one. Clean your dopstick and stone with alchohol and if your stone isnt heat sensitive warm it up as well. I use an alchohol lamp and dont usually have any issues. When I transfer I put some oil from the side of my nose on my finger and lightly oil the pavillion and stick the stone momentarily into the warm wax and make an impression and then let it cool. Next I clean the stone and impression with alchohol and then super glue stone into that impression. Always ask if unsure. Find a local faceter if you can. I’m in California foothills.
