when you return your old ring that you have been wearing for 5 years,
they reappraise it, and yes, take off a few hundred dollars off for usage (considering that they have to take the stone back to the lab, have it repolished, which'll make it smaller, it's understandable.) even so, they do give you back about 94% of the original price of the ring back (that's minus the tax from the time of original purchase.)
then that goes into payment for a new ring, that has to be twice the amount of the original ring (at the time of purchase, no tax) and a few hundred more bucks added for the restocking fee.
as for me, i got married 4 and a half years ago with a 1.5 c f vs2 tiffancy classic setting which cost ...a little over 25k .
then i had it upgraded, yeah!! for a 2.5c same quality, which was little over twice the price. I wore my 1.5c carefully and didn't have much damage, so i got about 96% of the original price back, which was good.
So if you're thinking of upgrading, I think it's a good deal. they take your worn ring back.
My friend who got married around the same time with a similar size gia cert ring wanted to have hers upgraded to a 3carat on her 5 year anniversary, but most jewelers refused to give her more than 70% of what she had paid 5 years ago.
So she decided not to trade in and keep the 1.5 and turn it into a necklace,
and just bought a 3 carat ring with cash.
Since we don't have as much cash lying around, being able to trade in the original ring at a good price was a real saver.
plus, i buy little accessories and gifts all the time at the store we go to, so the sA actually didn't charge us the restocking fee, which was a few hundred bucks.
I say, it's a pretty good deal.
and the new, bigger!!! ring sparkles like crazy.
