Jewelry, Gems, & Minerals/Larimar


What is the best way to  shape and polish rough cut larimar. Also best way to set stone: drill hole for simple bail or do bezel setting?

I have not cut Larimar myself but the stone cutters and Dominican Republic will cut Larimar to all forms many shapes teardrops hearts whatever the trick is to save as much as the blue as possible... Generally Larimar will come in many patterns and a lot of white swirls the best result is keeping as much blue as you can and not wasting it... Now I have to tell you, I'm not a cutter, but Larimore can easily fracture you can have a oval for example almost done and  an end will just crack off... I think it comes with experience and which direction to cut it on... I can tell you this if you're using diamond bits for drilling holes... Do anything you can to avoid drilling.... My experience, cracked pieces holes that are not straight holes that are oval-shaped... Just a real mess. And that's with diamond bits using water as a coolant..
I have no experience with ultrasound drilling you may want to look into that. If you're going to be doing a lot... hAnd mounting is the best way because is generally hard to make Larimore into exact sizes without wasting too much stone... Please let me know if I can answer any other questions

I will answer any questions regarding semi-precious stones or precious stones. I will answer questions regarding mounting both semi-precious and precious stones. I can also answer most questions regarding small manufacturing. I can not answer questions regarding casting or fine jewelry.


I am a small manufacturer of jewelry for semi-precious stones. I have been working in this area for 10 years. Our Major stones are Larimar (from the Caribbean) and Dichroic ( a man made crystal ). The majority of our work is in silver and 14k gold. We do not deal in fine jewelry such as diamonds..
