What is the value of topaz?

From The Image.Com:\n\n"Clear topaz has little value, and is quite prevalent. Some varieties can be irradiated to various shades of blue, and this acceptable in the trade. Most blue topaz on the market today is irradiated. There is a grayish variety of topaz that is sometimes cut to produce a stone called "champaign" topaz. "\n\nCheck out the link for further information about the other colors of topaz and their scarcity, etc.

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.

first if it was appraised a long time ago for 23K, it is probably worth considerably more now- especially if it is a canary diamond with few flaws--i know enough about jewelry to be dangerous- i would check the yellow pages for estate jewelers or jewelers who buy estate jewelry-- if one of these fellows buy your ring, they would give you the wholesale value not the retail value or they could not stay in business..you could try and sell it through the want ads, if you had a current appraisal and knew its value--yet that could also be dangerous with a valuable ring--that is worth a lot of money- i know an estate jeweler in dallas that would give you a fair value and or appraisal for the ring- then you could decide what you wanted to do thereafter--i am a retired CPA & CFP- if i can be of further help- holler back at me- good luck to you- by the way- you should get a current appraisal on the ring and make sure you increase the insurance on the ring to the current replacement value !!

This is really hard to answer. It's not like there is some New York Element Exchange where traders buy and sell elements. If you mean what is the monetary value of an element, there are some that are pretty easy to determine,  since metals like gold, silver, platinum, palladium, aluminum, copper, and other metals are used in industry. But if you want to know the cost of hafnium, then you aren't going to find any one answer, if you can find one at all. \n\nIf you want to see what the metals market prices are go here:http://www.metalprices.com/\nThat will give you most of them. If you want to see the cost of gases for industrial use, like nitrogen, oxygen, hydrogen, helium, you'll have to contact someone like Praxair or Airgas to get a quote.\nhttp://www.praxair.com/praxair.nsf/0/6021E2747E378CF285256B9F0070368D?OpenDocument

They are artificially held up in price by DeBeers and associated firms, there are actually huge amounts of diamonds being held back from the market to maintain the price levels.  The diamond cartel also funds massive ad campaigns to create a market.  The truly valuable gems are large, uncrazed emeralds, spinels, peridots, and sapphires...especially star sapphires (red sapphires are called rubies).  Large, well cut aquamarines are good value as well.\n\nAvoid opals and pearls....opals craze very easily if not in the proper humidity, and pearls can wear through the nacre after just a few years of being worn and rubbing against clothe.

Depends how much carat gold your jewels are made of, or if mixed with for example silver. 24 karats will be of more value then 18 karats. You could have it checked out by a certified jewelry store. They can estimate the price for you. If it is old jewelry like from greatgrandma or something, the cuttings or the way that it is made or fabricated can sometimes be of more value then the value of the gold itself. In thta case a respected antiquedealer os shop is also worth visiting.

Not a lot considering there is a 1986 card of him out there that is worth much more. The '86 Bonds is from the Topps Traded series and is worth almost triple the value of the 1987 card. The 1987 Topps, though, is worth around $10, but I would sell high on it now and invest in another card because the value of Bonds' cards will go down with all of the controversy, much like the McGuire and Jose Canseco cards have.

Being a variety of beryl it belongs to the same family as emerald. Its colour varies from an almost white pale blue to a slightly darker sky blue, this latter being the most prized of all. There are also some greenish blue specimens which potential buyers would be wise to avoid. When investing in aquamarine, choose a stone that is pure, brilliant and as dark as possible. Be careful not to confuse it with blue topaz, a far less valuable mineral.\n\nGenerally, aquamarine is faceted, except for the translucent or milky specimens which are better cut en cabochon. This cut is popular today with jewelers for the creation of reasonably-priced parures.\n\nAquamarine comes from Brazil, Madagascar, Russia and the USA. Specimens from China and Colombia tend to be of a yellowish tint.

An item has three possible values: the value to you, the fair value, and the value to the buyer.  Unless the watch has no value to your family as an heirloom, you could put the thing on Ebay and cross your fingers.

Check with a couple of local jewlers, shop around and get some info before you commit, they will talk to you and help you out, plus ALLWAYS negotiate the price most will move, just tell them that "that one is the one I really want but it is a bit higher than I can do now and will have to wait", it works, try it  xoffice.com

I have about 5 of those complete sets. Knowing that they are only worth about $10. for the complete set, I would say that the card is probably worth about 50 cents.

It depends on what the condition is.  Even in poor condition it's never worth less than $1 and would be worth at least the silver value.  Remember, anything is worth what a buyer is willing to pay for it.  Check recent Ebay sales, the price list on pcgs.com, or recent coin mags to get an idea.
