18 kt white gold diamond “endless” circle pendant consisting of 0.64 ctw diamonds

The diamonds look like they are of VS clarity, at least eye clean although

I am not a jeweler

Comes with original purchase receipt

I believe this is a designer piece because it is stamped but I can’t make out what it says

Looks like “UIDC 750”

I know the “750” refers to it being 18 kt gold

When I bought the necklace I recall it being IJR brand but the stamp doesn’t say that and that name is not on my paperwork

It falls 18 inches down

In excellent Preowned condition
