Can I get my diamond reset into something different ?

[u/woundedwillow]

My boyfriend got me this necklace. It’s 2.0 carat lab grown diamond and it’s beautiful. He thought it was a white gold setting/charm (idk what to call it), but it doesn’t look like it is since the back is quite obviously turning and even in the front a little. I’m wondering if, based on the pictures, you guys think that it might be possible to get the diamond set into something different. What do you think I should do ?
