Is Tirquoise considered a precious gem?

It is interesting that the term "semi-precious" is no longer accepted for use by the international jewellery trade organizations with good reason. For example under the old system alexandrite is semi-precious and yet prices can reach $50,000 per carat and more, the same with tourmaline where Paraiba material can reach $20,000 per carat and so on with a whole list of other examples, hardly what one would call SEMI-precious. To answer your question, yes turquoise is a precious stone.

I think size matters in this case; the smaller the better.  You can store your jewellery in a safety deposit box when you travel, but it's hard to keep your art pieces secure.  Also, gems just keep appreciating in value, whereas art is harder to predict.  Go for the sure thing: jewellery.

The more rare the gem, the higher the price and few find them

All gem stones, (Birthstones all of them) are beautiful to wear when it reflects the month that you came into the world. All gemstones have a unique effect on  the body/ system. Some effects the blood stream/ circulation, stress, anxiety and even radiation (people who a near computers or machines with a lot of radiation coming from them) \n\nThis website, tells information for all (or most) gemstones. All birthstones can be found in here. They also explain what each can do to "heal" the body.\n\nI had a necklace that helped me with headaches from being on the computer. This stone fluorite was on the necklace was helping because of the radiation that came from the computer.\nThey are very facinating thoes beautiful stones!\nGoodluck finding what you need.

Le trophée pèse 3175g d'or massif 18 carats. Si un scélérat s'en emparait et le fondait, il en tirerait déjà $71455 !!! Si l'on rajoute la valeur de l'objet, on comprend mieux l'étendu du service de sécurité encadrant ce trophée.

An ore has minerals or metals suspended in a base, unwanted material that needs to be refined to make the pure mineral or metal usable.\n\nA gem is a crystaline material that has some intrinsic value.

If you've put this question in "Investing", then it is worth nothing.  Gemstones of poor quality (ie. poor color, clarity and /or cut) are not worth your investment unless they have something special about them - ie. they are extremely rare or they have a unique or special inclusion etc.\n\nYou haven't elaborated why you think your stone is of "poor condition" so it's difficult to say how much its monetary worth might be.  It depends largely on color, clarity and cut.  \n\nAssess your stone by asking yourself these questions:\nIs it a pure red? Pinkish-red? Orangy-red? Or does the red have undesirable brown modifiers? Is it transparent? Is it translucent or opaque?  Are there visible inclusions? Are they distracting? Do they affect the stones aesthetics and/or durability? Is it cut well? Is the stone cut too deep or too shallow?  Is it balanced? \n\nStones that are pure red, transparent, eye clean & well cut will fetch the highest market prices.  Stones with poor color that are opaque, included and poorly finished will not be worth very much.\n\nSend me an IM with an url to a photo and I'll try to help

Mostly, this is a bit of poetic license by the author of the song.\n\nHowever, it is founded in how you go about refining gold ore.\n\nWhen you're refining or working gold, the more pure the gold, the more desirable.  This is expressed in the karet figure - 10k, 18k, 24k, for instance.  \n\nSo, presumably, if it is God refining the gold, it will be as pure as it possibly can be, and therefore of the highest value.

Woah I just answered this question. Weird. The 15 year gift is Crystal. As in, wine glasses, etc. For gemstones its Ruby.

In my opinion, it depends on each individuals preference for jewelry.  GOLD seems to be the favored precious metal because of its value, both by rare availability and its historical influence to our greed and vanity. PLATINUM and SILVER comes in as a close second place.\n~meow

Gemstone quality crystals can be made into jewellery and so are vauable. Others are useful for their ores (hematite Fe2O3 iron ore, malachite copper ore etc.) I also heard somehing about using crystals for resonance but I'm not sure what that means lol hope this helps\n\nP.S. Quartz ie. silicon used for glass

Is this for an engagement ring? If so, maybe you can consider another stone, rather than an imitation. Lots of women I know have citrine, sapphire, or other stones for their engagement rings. (It was good enough for Princess Diana, though her sapphire was surrounded by diamonds.)

a diamond, it has a universal appeal due to its lustre and brilliance

Color, cut, clarity, and carats - the same as for any other gemstone.
