Many of these cabs are the small calibrated kind that will fit into commercial settings. Also, you can make your own bezel for your own creations.
The free form style stones can be set in your own bezel or for wire wrapping. It is up to you how you use these stones (just don’t let small children or babies that might be by your side put them into their mouths as the stones are slippery when wet and will go straight down. I might give you a little comfort though here: “The small ones will go straight out also in about a day.” Well, so much for the laugh for the day” but I am sure it would not be a laugh if you saw your little one put one into its mouth. Keep them safe.
Enjoy using the creative talents God has given you and choose your stones thoughtfully. I try to have my stones inexpensive so the cost to even practice and develop your creative jewelry making talents should not be overly expensive. God bless you as you still learn and practice your talents to increase your skills.
Thanks for looking. Larry E. Whittington
