what does OB 10K mean inside of an old ring?
468222
The 10K stand for the karat weight of the metal, normaly used for gold and platinum. The OB may stand for many things. Im sure someone will correct me on this, but i dont know of any metals used in jewlery that is named as OB. It could be the makers mark, as many crafters used to put their initials on things, much as many artists sign their paintings or have signature trademarks.

It is stamped "825 China" probably because it is made in China. The 825 is the code for Continental Silver (European) and it means the alloy contains 82.5% Silver.\nThe millesimal fineness (a system of denoting the purity of Platinum, Gold and Silver alloys by parts per thousand of pure metal in the alloy) for 14 carat Gold is 585 and for 10 carat Gold is 417, therefore the Gold jewelry would be stamped accordingly.

like your 1st answer said, contact whoever made your high school ring, be it jostens or art-carved.  Your old ring is history, join the club, but you can have a new one made.  My high schools, moved in at the end of tenth grade both used Jostens.  If you played sports you probably had a symbol on the side, mascot on the other. call or email jostens or your old high school to get company they used in whatever year and contact them. they have blanks and they can punch you a new ring you pick the stone color or gem and the metal mine was lustrium (some nickel, platinum, silver,palladium combo) but that's what you get for $250.

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.

The old currency usually has an expiration date.  However, it can be different in every case.  Check with the country of concern.

take it to a bullion dealer - the prices are fairly well set - it is worth around a thousand dollars, there is a charge for storage etc. but the price should be around 90% of the actual oz. price.  you will make a hundred or so dollars more if you sell it private - at the rate - or slightly more.  Try a silver smith too - find them in the yellow pages, but first find out what the bullion dealer will buy it for. and what they sell it for - that is the least you will get for it.  they sell it for more than the stock price, and pay less than the stock price.

Your best bet is to take the ring to a jewelry store and ask them about the ring. Some people who have been in the buisness a long time may be able to tell you some of the history on different stones etc.

The G&L most likely refers to Gondolo & Labouriau, sometimes spelled Gondolo & Labourian, a high end Brazilian jeweler which has been around since the late 1800s I believe. That should get you searching. Good luck!\nYou may want to take it to a reputable jeweler to have it appraised.

You're going to be wearing this ring for a long, long time, hopefully for the rest of your life, so for heaven's sake, get what you like! A good bet is to think about the jewelry you wear now, the stuff you find yourself grabbing again and again because you prefer it and it flatters you (watch, earrings, necklaces, etc.) If it's mostly yellow gold, then that's probably what you should choose in a wedding ring.\n\nAnd, no, there's no reason in the world that your two rings need to match. You are two different people, with two different styles, which is a great thing, and should be celebrated. (by the way, my fiancee chose an antique styled yellow gold band, and I chose a more modern styled white gold one. we have the same psalm inscribed in our rings, which unites our two very different styled rings.)\n\nGood luck, and congrats!

You need a Numismatist. Here is a link. You will need to have it inspected. Usually you can check your yellow pages and find someone qualified.

It means the same a 99 from a goldsmith one from a black smith\n\nTo elaborate - thief tries 99 times and owner does it in one day, A thief may try for 99 days to steal, whereas an owner can steal in one day
