Jewelry, Gems, & Minerals/turquoise


Hello, I liked your blog so have an additional question for you.  I have to unset a long, 25mm, oval good quality turquoise from a 1//2 bezel setting to repair the back.  The stone was super glued into the setting.  If this stone can't be soaked in acetone, is there any other method for removal?  I'm considering using ThermaShield to protect it while I unsolder, repair and re-solder the piece.
Any suggestions will be appreciated,

Dear Debbie,

Please use a follow-up to tell me exactly where and what is to be soldered.  Distance from the stone and metal is critical if using a heat protective coating. Is the metal silver?  Make a simple sketch or send photo if possible.

Also,in the meantime, you might find out if acetone will damage the stone using two tests.  First, take a sewing needle or similar piece of metal. You want a small end to heat red hot with a flame, then touch to the stone on the backside or other area likely not seen when stone is set completely. When touched with the hot point, plastic impregnated stones will generally have a hot or melted plastic smell.  The small point helps minimize any damage to the stone. The second test is to apply acetone to a limited area with a q-tip or if the swab is too large, cut it off and use the end of the shaft.  Rub with some pressure on one area and check to see if the surface becomes in the least bit sticky or if any color shows on the applicator.  Small areas of plasticized stones may be polished with a white buffing compound using light touch.

When I have a better idea what you actually need to solder, I will be able to give more accurate advice. I look forward to hearing from you, Debbie.

God Bless and peace.  Thomaa.

Have a question about jewelry repair or working with precious metal jewelry and gemstones? For many years up to December 31, 2010, I was a working professional bench jeweler, involved everyday with setting stones in mountings, designing and making jewelry, repairing and limited custom manufacture. If you work with jewelry as a hobby or as a profession, I might be able to help. I deal with the retail business, not mass production. Ask privately if you wish. See the box for that: It keeps your question between us. Please DO NOT ask MAKER'S MARKS, but metal quality marks are fine to ask. Please DO NOT ask diamond prices. See a gemologist for that.


I have extensive experience in design, service and making of jewelry. I deal mostly with precious metals and gemstones but work with many materials as needed and usable to create an artistic design. My experience also includes freelance photography and photographer of jewelry and similar items for a former employer and individuals. Design of custom items requires reading the desires of the client and being clear on what can be done within that framework...then fulfilling the transition of idea to reality. Effective communications is essential in a working designer/producer and customer relationship.

Education is English/Physics! Started in human resources, to advertising, to, what a road. I have had formal training in jewelry work and many shared experiences with top grade jewelers. We just never know were we will go or be. Follow your best, your dreams, with some discretion! Don't let the work tear up your body along the way as it has mine.
