How closely should a pair of diamond earrings match in size?

Diamonds are matched and paired when they are made into earrings, basically, they should be very similar in carat, color, cut and clarity.  They should be mounted with the same styles, thus you are not supposed to tell the difference with your naked eyes.

get a fake one from swarofsky -- nobody can tell but a jewler

You should get 2-3 prices from different jewelers if possible.  They will often offer more if they know you are shopping around.  You should also make an attempt to find the owner.  Some diamonds are marked and can be traced.

Take it to a jeweler.

I do and don't recommend this. I'd hit them with something hard, but not too hard to make sure that it wasn't glass. If it breaks it's not a diamond and if it chips it might be fake, but it might be real. The best way to find out is to go and get it appraised at a jewelry store

same way as you find a very good pair of shoes.  you gotta shop around a try a few on for size.  when you find a pair that not only fits, is comfortable, but also goes with any number of outfits, go with that one...  ;-)

I would take it to a jeweler, there is no way to be able to tell if a diamond is real just by looking at it. They will be able to test it for you. It might also cost some money, just depends on the jeweler.

you might want to take a look on ebay to look for a real diamond ring or maybe a pawn shop will do it instead of a fancy jewerly store...

I think diamonds have to follow a universal standard regardless of what store is selling them. Do some research if you are worried. From my own personal experience, my husband and I both bought our wedding rings from Penneys five years ago. Have had no problems. Not sure there is a difference between the large "chain" store's jewelery departments and a Zales or another store that sells only jewelery.

Stud or small hoops as everyone said.  But they must be silver.  Gold earing looks terrible on most guys.

I did a quick search on www.bluenile.com-\nThere were no diamonds which met your exact specifications, however the closest was a .24 ct E color ("D" is colorless), Internally Flawless (a grade below flawless), Ideal cut.  It was selling for $786.\nA .26 ct Good cut, D color, Internally Flawless stone was $610.

I hope you mean the ring itself, and not the diamond.\nTake it to a jeweler.  They can put a little adjustable band thingy on it so it will fit the finger better.  That costs about $5-10.  Or they can torch the ring & actually MAKE IT smaller.  Won't work on CZ's, because they'll burst, but a good quality diamond should be able to withstand the heat used to modify the size of the ring.

Any jeweler should be able to size your ring...but if you go to the jeweler where you bought it, you probably won't have to pay for it...
