Yes, that's true, they do take workmanship into account too when giving a price.
They will look at the diamond and will be able to test the carat weight with a special gems testing "thing", don't worry they won't need to dismantle anything!
I think you also get allowed a bit more if you've got your eye on another piece to trade it for rather than just wanting the cash.
Of course you could always visit several jewellers to get prices to compare... everyone's got their favourites, there is a thread here somewhere about jewellers.
