i have a loose Oval Diamond, of 1ct its Measurement are. 5.26-7.75-3.45
i saw for sell 2 mounting that like the seller idndcitet:
the first mounting: is for 1ct stones and if for 7.7X5.5
the second: is for 0.75 stone and is for 7X5
since both do not match exactly my diamond i was wondering if i order the seating will a local jeweler be able change any of them easily to the measurements of my diamond?
how flexible is a jeweler with adjusting the mountings?
