Title: Sealers, to use or not to use.
Post by: CedarTree1325 on October 20, 2017, 10:12:35 PM
Years ago as a teen I use to make cabochons. Im now retired and have my own shop to make all the cabochons!  I realize times have changed, is it correct to use a sealer on the stones, after I have polished them? Also, can anyone recommend a sealer, can I use? Your help appreciated and many thanks in advance.

If your stone is solid and not crumbly or pitty, there's no need to treat your cabs.  Stabilizing stone decreases the value.

If you want to stabilize or fill pits in some material, there are a few options.  Opticon is an old standby.  You could also try Hxtal (https://www.hisglassworks.com/shop/catalogsearch/result/?x=0&y=0&q=hxtal) or Bond Optic (do a search - I've gotten it on Ebay, but haven't used it yet).

Hope that helps.

Thank you for the quick reply!
Yes, the stone Im concerned about is a lapis, where a tiny corner of about 1/32 broke off. The stone is in a noticeable and precarious area of the bracelet, so a repair is needed. I made the bracelet two years ago, and the owner is just now getting it to me. I would like to grind down the stone to be flush with the bezel area, but I feel that would still leave a pit, so a  slight build up of the pit/corner may be my only option. Thank you for the info on opticon and the two other options  :toothy10:.  I will research the 3 options you provided and, reply once again, should I have further questions. Kindest regards.

If you have a small piece of lapis you could crush it and mix it into 330 epoxy and fill the damaged area than grind and repolish. So you don’t have a clear area showing
