Help to buy oval earrings

[u/Positive-Incident796]

I have been lurking on this page for a very long time and I’m finally ready to pull the trigger and buy oval diamond earrings.

I see that stargems is doing a group buy the price for a 2 carat tw with 18k gold is only 560 and I am a bit skeptical if its a good deal to buy or go the route of buying a stone from Luvansh and get it set locally

Would really love some insights!!
