Where can I get the market value of a diamond I have?

If you get your diamond appraised at your local jewellers & they appraise the diamond through one of the gemmological laboratories (for example EGL, GIA etc) then they provide a laminated certificate with the diamond grading info plus you can look it up on their websites following receiving the certificate by entering the certificate number given to you. Hope this helps!

List it on Ebay for a penny and see if anyone bids - that's what it's worth....whatever the market is willing to pay.\n\nBest wishes,\n\npup

eBay will give you a good idea of the current market value of the item in question.

Diamonds are not rare. South Africa has a bunch in storage that they hide until the current ones are sold.\n\nAs for worth, that depends on the size of the diamond, cut, clarity, and flaws---and the current market price.

Just a Guy ~\n                     EBay, Brother. Put up a price and a description and picture and let the people come to you with offers. Then you'll get an idea of what they are worth.

You'll have to get it authenticated.  If it is, it's worth several thousand and up depending on the condition.  Look on E-bay for completed items similar to this, that would indicate a base price.

Getting an accurate history of diamond prices is difficult since different types have appreciated differently. I don't have estimates for 2005. If you  look at the 1st link (page 4) you will see that rough diamond prices have gone from ~1000 to ~1800 from 1980 to 2004, an increase of 80%. From the second link you can see the consumer price index went from 246.8 to 565.7, an increase of 129%.  Rough diamond prices have gone up less than inflation.  (I can't find comparable figures for cut diamonds, but they tend to follow rough prices.)  The next problem is that you buy retail and sell wholesale, and the wholesale price is often 1/2 of retail. (See third and fourth links) I don't think of diamonds as a good investment. (Except my wife likes the one I got her, so it was a good investment from that standpoint)

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 !!

Worth of course depends on how many people are wanting to buy it.  On of the best sources to get it out there and seen is to take a picture of it and sell it on ebay.  There is a huge huge demand for minerals/crystals of that nature on there.  I know because I buy alot of my crystals on there.  See if htat works for you.

eBay is a terrible place to assess value for anything other than the most high-end, hard-to-find items. Buy a copy of Becket Baseball Card Monthly, the standard for card prices. \nI agree with the above poster about the umm, design for the 1987 set. However, I would revise the valuation upwardly to, perhaps, around $50, based mostly on the strength of the McGwire card and the growing appreciation in prices of 1980s sets. But definitely check this with BBCM.

If it has sentimental value, take it to a jeweler and ask what it would cost to have it replated.  Try a locally owned jeweler rather than a mall jewelry store.

The best way to get an accurate value is to check a Beckett guide...they sell them at stores and card shops, or you could go to a local card shop and ask them the value. Once they give you a value....type the card description in a search on ebay and check the completed listings.....this will tell you if it is currently a marketable item....you can usually get somewhere between the ebay price and the beckett price if you decide to sell. Good Luck

Current market price for platinum is approx $1040 /oz. There is really no answer to your question because it depends on the quality of the diamond. Industrial diamonds can be purchased for less than a penny an ounce (< 50 cents per carat).\nTop quality diamonds can go for millions of dollars apiece. It all depends.
