I have a resin 'charm' (not sure what else to call it)  that's make out of sand. A tiny piece of the resin broke/chipped/snagged/?? and the sand is slowly leaking out! 

Is there any kind of fix I can do?

I've never done resin work, so I'm less than a novice at the technique. Thanks!

Can you put a picture up so we can see what we are working with?  You could probably do a patch job, but I think we need to see what the problem actually is.

Sounds like a depression you could just pour more resin into if you brace it in a pile of rice/etc facing upward (carefully though so won't disturb the sand, or add a few drops of polyurethane on sand first), then perhaps coat the whole item with epoxy resin again (or epoxy covered with polyurethane, or maybe even just the polyurethane).  Any of those things should form a solid clear covering without showing any margins of new resin/polyurethane.  
Good idea to first "clean" the area of join with a bit of acetone, with a brush or tiny q-tip then let dry, anuwhere you won't be disturbing the sand though just to allow a better bond.

(If you don't know the difference between the types of resin there are, check my answer here:

...and if you want more info on "coating" resin or other materials/items with epoxy resin, check out the resin page at my site under > Epoxy >> Coating:

here are some pictures, not sure if it shows the chipped/cracked/whatever resin, because honestly, I can't SEE it Smiley

The entire pendant -



at the pendant tip on the edge away from the bail, (the right edge of the picture) the resin chipped or pulled off or something, and the sand drips out

I tried to get a close up of the edge, the 'chip' is the center, a little to the right of the pink dot -

Diane - thanks for the info. I'll see what I can find at the store. There's a bead store that has resin classes, I'll check there too if they do repairs.

Ah, okay, thanks for the pic.  So looks like there are several good ways you could repair this:

...mix up a small amount of epoxy resin (I'd use a "regular" epoxy resin like Envirotex Lite)...stand your pendant (eyepin down) into a pile of rice/beans/etc so it's exactly vertical...drip just a tiny bit of resin onto the end over/into the leak area...let resin cure...next day or at least a number of hours later, if the margins of the repair don't look smooth and it bothers you, mix up a medium amount of epoxy resin and coat pendant all over (or dip it) using more epoxy resin or using clear polyurethane** (then hang pendant and drip till dry or cured, perhaps wicking off any excess at bottom in the beginning)

...do the same thing as above, but use polyurethane alone instead (or even clear fingernail polish) ...polyurethane will harden (dry, in this case) much more quickly than resin, but it is thinner so may have to do multiple coats to make the areas totally even (it's not a bad idea to add one coat of polyurethane all over an area of epoxy resin anyway since it's tougher than resin)

You won't get *sand* in that little truncated end of the pendant where the leak is by using plain resin or polyurethane, but if you want to go to the trouble you could (thoroughly) mix some sand or something else of the same color into the tiny blob of resin you drip onto the leak area...then do the all-over coating if you want in the same way as above with clear resin or polyurethane.

** hardware store, or you can buy it sold as a finish for polymer clay under the name Studio by Sculpey Clear Gloss Glaze (the old Sculpey Gloss Glaze isn't the same and not as tough, but thicker and could work reasonably well)
