Hi, I am not at all experienced with diamonds so I am hoping you can help. I have a platinum wedding set that I no longer use. The e-ring has 8 prong set round diamonds (4 on each side of the center stone). The matching wedding band has 10 prong set round diamonds with a space in the center to accommodate the low set large e-ring stone (so that the bands can sit flush). I went to a jeweler to ask what the cost would be to melt the rings and make a platinum eternity band using the same diamonds. He offered me a $800 credit for the set toward a new purchase, or would charge me $600 (mainly cost of labor) to make the eternity ring from the existing material. He would not need to add more diamonds (I'm a ring size 4), and he would keep any extra platinum. Is this a fair price? Thank you so much!!
