I purchased a baggie of rough emeralds with matrix attached. How do I clean them without harming the stone within (if there is anything within)

Hydrochloric acid will gt rid of limestone, and i don't thin it will do anything to an emerald. For other kinds of stone, saw away as much as possible as close to the gemstone as you can. Then facet it. The faceting process will remove the rest of the matrix.

Use a mild hand or dish soap. Just make sure you rinse them very well, to get rid of any soar residue. Also it is better to let them drip dry, if you use a towel you will end up with fuzzes all over them.

Here's the pages with the info. You'll have to read fast. Don't wait so long next time. Good Luck!!\n\nhttp://mineral.galleries.com/minerals/gemstone/aquamari/aquamari.htm\n\nhttp://mineral.galleries.com/minerals/silicate/garnets.htm\n\nhttp://mineral.galleries.com/minerals/gemstone/class.htm

That depends on many factors. First of all, you would have to weight the rough stone and determine how many carats each was. Then, and most importantly, you have to judge the quality of the stone: intensity and quality of the color, inclusions, origin of the stone, and how much of that rough could be used into cutting the stone. \nIf all three stones were top quality (from top origins, and without treatments, top color, clarity and so on), it could be something like: Emerald, Ruby, Sapphire. \nStill, take into account that this goes by particular specimen (and this applies to many gemstones) and not so much by species. \nRough, uncut stones are hard to judge, since the inclusions are harder to see, and you don't get a good sense of color. \nYou can probably get a good piece of rough stone for not too much money. If you are looking to have it cut or polished, though you may be disappointed, as very little of it may be useful. \nIf you are looking to buy stones to wear, I recommend that you look into cabochon cuts: this cut makes the color look beautiful, whilst using lesser quality (clarity wise) stones, so it's not as expensive, and you may find big, beautiful pieces that are ready to be set. \nHave you considered buying spinels? They come basically in every color, and they are so shiny that they glitter even in their rough, unpolished forms. \nGood luck!

What you need is a plastic bucket (unless you're willing to clean your clubs in a bathroom or kitchen sink), a mild dishwashing detergent, an old toothbrush or other brush with plastic bristles, and an old towel for drying.Squirt a little of the dishwashing liquid into the bottom, then add warm water to create suds. Make sure the water is warm, not too hot (very hot water can loosen the ferrule on golf clubs).\nYou only need enough water in the bucket to cover the heads of your irons\nAfter 1-2 minutes of soaking time, take each club in turn and use an old toothbrush (or other plastic-bristled brush) to clean out the grooves on the clubface. This is the most important step in cleaning your clubs - removing all dirt and debris from the grooves. \nAlso drag the brush across the sole of the iron and over the back of the clubhead, removing dirt, grass and other debris. \n\nA soft-bristled brush should work fine. If you've allowed dirt to build up in the grooves and harden over time, you may need to allow more soaking time and then use a stiff-bristled brush. Never use a wire-bristled brush during cleaning.\n\nUse your old towel to dry off the clubhead. Also drag the towel up the shaft of the club. This will remove any loose debris from the shaft and also ensure that the shaft doesn't go back into your bag wet.\nNever submerge persimmon woods in water. It's a good idea not to submerge metal woods, either, because they usually have a nice, glossy finish.\nInstead, quickly dip metal woods into the sudsy water, rub with a moist cloth, then dry with a dry cloth. Use a moist cloth to clean off persimmon clubheads, then dry immediately.\n\nUse a soft-bristled brush, if necessary, to clean out the grooves on woods.

You mean you need to meet buyers of rough gemstones.\n\nI think you should try contacting an American tutor first. Then seek out those who speak your language and try your hand there first. But in the mean time, here is a start.

mix it...let NaCl dissolve in water...then let the mmixture evaporate or perhaps bring the mixture into a boil 'til you can see the formation of crystals...   try it... i've encountered such experiment in my chemistry class... im not quite certain of the procedures though...it's two years ago...cant remember it well...^_^

A dark green stone with light green flecks..hmm, could be jade.  But it could be something else too....a quick trip to the jeweler or to a gemologist will solve it! Really, all you need to do is get a specific gravity measurement on it (i.e. a ratio between how much the stone weighs in air versus in water).  Jadeite is 3.33 and Nephrite is 2.95.\n\nHowever, there are a few quick tests & observations you can conduct at home that might shed some light on what you have.\n\nHold the stone in your hand.  Does it feel cool to touch?  (You may have seen Chinese or Burmese people touch jade to their cheeks to test its coolness as a sign of authenticity.)  \n\nObserve the texture of the material. If there is a fracture, the texture should be splintery and rough.  If it shows fairly smooth flat surfaces and "faults" (cleavage planes), you may have another type of green stone. e.g. Amazonite. \n\nIf it is polished, does it look like it has a "dimpled" skin? Can you see tiny veining on the surface? If it is translucent, does the material look slightly fibrous?\n\nIt's really hard to say what you've got based on your description.  As a collector, I'm pretty good at visual ID of jade.  If you have a photo, send the url to me and I'll do my best to help!

Either take them to a local reputable jeweler, or a pawn shop, or post a classified ad in your local newspaper. Or, best case, get a refund (or at least a store credit) from the jeweler where they were purchased.

Possibly when the ring was new, it had a layer of clear hard varnish which has now been buffed off.  The scratches it used to get were scratches in the varnish, not in the ring itself.  But find another jeweller and get a second opinion.

no just clean it & keep it  dry.\n\n~vadge~

Go see the doctor and see if they can remove the stone or help you to move it out.

I would say just be happy that you have a man that would buy you nice things, but if it's just killing you to know, take it to a reputable jeweler to get it appraised, but be careful about leaving it over night because I saw a 20/20 report about jewelers taking out real stones and replacing them with crap and if yours is real you may get ripped off.

make sure whatever you wash it with doesn't get between the chip and the card.\n\nCoke may dissolve whatever kind of glue holds it on.

Get a can of stripeze....careful when using tho...highly flammable. follow instructions and do it outdoors. DONT bead or sand blast them! If you do you will never get the polished look back! Rinse them good. Get some simichrome polish or other type of polishing compound. Be ready to use some elbow grease...you might want to buy a buffing disk for your electric drill.

Do not crush the rock salt as this will make the impurities harder to remove.\n\nDissolve the rock salt in very hot water and filter.  If the filtrate (the water that comes through the filter) is colored, then you might need to treat it with charcoal to remove these soluble impurities.\n\nOnce you have a clear solution, allow some of the water to evaporate until the solution becomes saturated.  A single seed crystal will start the formation of sodium chloride crystals from the solution.  Stirring will keep the crystals smaller, otherwise you can end up with one very large crystal of salt.\n\nThis crystallization process is what does the final purification.  The crystals formed will be almost pure sodium chloride.

Hematite is cut and polished just like any other rock/ore. I'm unsure how to go about removing marks from it though.
