Recently we have received a question asked via our online form about repairing cracked sapphire gemstones. Somebody also asked a question about how to repair a cracked jade stone. These seem to be common problems, since many types of crystals and minerals, as hard as they migh be, exhibit various microscopic and (sadly) macroscopic defects. We are always sorry to hear about such issues, especially if it happens to a favorite jewelry item, meditation stone, or a crystal dear to your heart.
While these kinds of questions should have been directed to a professional gemologist, in the following we will try to share our (somewhat limited) knowledge on how to deal with such problem.
Please note that this is a general discussion. In reality, it all depends on the type of mineral, color of mineral, and on the specific fracture to your stone. Paradoxically, a more difficult case could be a gemstone with a fracture only visible on the surface, but extending deeply in the bulk, as compared to the totally broken stone. This is due to the fact that it might be impossible to completely fill up the crack with glue material in a partially fractured stone. This, however, is relatively easy to do on a totally broken natural gemstone, provided that there are only two or three broken pieces and that all of them are accounted for. Hughes 330 epoxy is good for such complete breaks. It is a very good cement for inlay.
In any case you need to consider leaving this repair in the hands of a skillful and experienced jeweler. Even better, try contacting a rock shop manager who, by the nature of his everyday job, should be familiar with how to use epoxy on gems, crystals and minerals. If you still want to try it for yourself, you can play with some of the most popular lapidary epoxy glues.
Epoxy 330 is water clear adhesive for all sorts of lapidary repairs. It can be used on rocks and gems as a transparent glue for invisible bonding. It is also good for ceramics, glasses, and metals. It can be used to bond gems to metal bases, gems to glasses and to fill cavities. It bonds relatively quickly, in some 15 minutes (10 if heat is applied), but the full strength is achieved in 2 hours. The test of time is the only viable test in these cases, so there's never a guarantee.
These sorts of adhesives are also used for making doublets and triplets of opal or in opal jewelry. If you need extraordinary optical properties, clarity and permanence (this is a must if you sell doublets or triplets) your choice is Hxtal.
Trained lapidaries will be able to apply pressure, heat and vacuum conditions alongside using these epoxy adhesives. Acetone is the usual solvent until the epoxy thickens - afterwards you would have to apply a long soak in paint remover. Using vacuum, however, might be questionable, as most experts, will avoid the risk of polluting their vacuum machines.
Know that there are some online gemology forums where you can get a more specific advice regarding all types of repairs on semi precious stones and gemstones.
This is an interesting question, and there is a debate going on as to what degree the metaphysical properties have been altered. We believe that the healing and spiritual potential of such stones is somewhat diminished, but that they remain useful.
Txs, it was very useful. Is there any special meaning if the stone is broken?? Any sort of spell broken?
I take it that your question concerns a stone previously used for casting a spell. Then, if the stone is broken, it is very likely that the spell is broken too. Not that you should use gemstones for casting spells in the first place.
Need to repair damaged murtis made of jade, lapia lazuli, crystal (spatika) and other. What equipment do you recommend. Thank you.
Thanks for the comment. In your case we are talking about a rather sensitive repair. I would suggest consulting an expert gemologist just to make sure that you are doing everything the best possible way. Sorry I could not be more specific.
The tip of my pyramide-shaped, green fluorite gemstone broke, what can I do to fix this? Also, what does this break signify, if anything? (It's part of a pendulum/bracelet)
Thank you, Versha
In terms of metaphysical action it shouldn't matter much.
What if your gemstone just has a minor chip? What would you recommend for that?
I wouldn't even bother about a minor chip. I would use it as it is.
Do you know any experts in Denver to repair specimens? I have a 2 very pricey stones to repair. Thanks!
Unfortunately, I don't. In any case, you would need a quality jewelry repair service. Maybe some of the readers of sunnyray website would be able to give you a good tip. Thanks for the comment.
I have a beautiful 1/2" checker board cut garnet that has cracked. The garnet is set in a ring. Can it be repaired without further damage?
Hi Patrice. In cases like yours, when you have something precious and beautiful, I'd leave the repair job to the professionals.
The tip of my pyramid-shaped polished amethyst completely broke of. The gemstone is small and and a necklace. What can I do to fix it?
My black onyx gemstone cracked in half in my senior class ring, is there any ways to repair it, all the pieces are still in the ring.
I would leave the repair to a qualified jeweler. That's by far the best way.
i have a blue sapphire. here i found a minor crack inside the stone. Is it dangerous or harmful for me if i wear it.
No, no danger at all.
i am wearing a green color gemstone on my right lady's finger but on top of gemstone in the corner side it got slightly broken or you can say a small tip got removed.
will it make any difference does the effect of stone will reduce.
please help me out, I'm little worried.
As far as I see it, no reason whatsoever to worry.
The tip of my white sapphire is slightly broken will it bring misfortune.
No way. Just please don't ever program that thought, or any other negative thought, in your subconscious mind.
I have a beautiful Chrysoprase quartz and noticed a slight cracked line in the stone. Should I be concern. Does it weaken the power of the stone. Thank you
My opinion is not really, or not to the extent that you would notice.
My fluorite point necklace has a fracture/crack the whole way across the Middle. Is there anything I can do to heal this? I've read things about burying it and stuff but I really have no clue. I've had fluorites before that have snapped straight in half and I really don't want this one to do the same
It is not easy to say if it will stay that way or crack all the way through. I doubt burying your fluorite would help. Maybe a gemologist could be able to fill the fracture with some transparent material to prevent further damage. They often do that to fill fractures in Rubies and Sapphires. Hope this helps. Thanks for the comment and I wish you all the best.
Hi, and thanks for being here.
I have a John Hardy ring with an agate stone.
There is a tiny hole near the center that seems to go through the entire stone.
Should the hole be filled, and if so?
Also, if it isn't filled, what is the risk or likelihood the hole will grow over time?
Thanks again, and happy new year.
No the hole shouldn't grow over time. Unless, e.g., there are microscopic cracks somewhere in the stone, but that holds for any type of stone or crystal.
I have a large opal (set in a ring) with a hairline fracture, partway through it. Can I brush a small amount of superglue gel on the back (to keep fracture from spreading)?
I have never done that, and I'm not sure if that's the best thing you can do. Fractures in Opal are often related to the well known property of Opal to lose water in time. Please check with a gemologist, what's the best course of action in your case.
Is there a chance that my citrine will repair cracks by itself if i program it to repair itself?
Although people report miraculous repairs, changes of shape and form, and similar manifestations, the likelihood of something like that happening is not great. That is not to say that you shouldn't try.
Hi! Thanks for a lovely site with great info! Yesterday a tigers eye and a moonstone came to me in two separate rings. This morning of course i dropped the moonstone on my night stand and i discovered a thin crack along the side. The crack is slightly black as if it has been there for a while and dirt got in BUT I didnt see that yesterday. So, if the crack is a result of my shaky morning hands - should I be worried? I was surprisingly upset by this but I take that as a sign of my already deep affection for my new gem friends.
Hi Dilan, and thanks for the comment, and no, you shouldn't be worried at all. Usually, what matters the most is your own interpretation of the event, not what I or anybody else thinks about it. Many blessings!
I dropped an ametrine pendant and a part of it broke off. Would epoxy be a good option for trying to put it back into one piece? Its one of my favorites to wear and to look at, but is also very sentimental so I'm willing to retire it and just keep the pieces to have if repairing it is too arduous or potentially harmful to the stone itself. Thanks!
If it is of sentimental value, I would suggest going to a professional jeweler. Otherwise you can try with the epoxy glue. Thanks for commenting.
I have a Watermelon Tourmaline Slice that broke in half during shipping. Is there any way I can repair it myself?
I haven't tried such a repair on Tourmaline. It is much better to give it to a professional if it has any special meaning for you.

Sir i have a blue stare sapphire it has a scratch and a minor crack. Is it dangerous or harmful for me if i wear it.
I don't think it's harmful, in the metaphysical sense, that is.
Hi I have a peridot that chipped and a chunk of it came off can I use epoxy 330 to fill it in
