Looking to buy lab diamond studs for family members, CHEAPEST PRICE?

[clorchicken]

Hi, looking to buy 4 pairs of lab diamond earrings for my mom, 2 sisters, and 1 SIL. Anyone know of the cheapest price for either 1, 1.5, or 2 ctw? I know it's a large gap but I'm trying to find the most economical way to do this. I found Luvansh has 1 ctw studs for $245 a pair with their 30% off code. Is this a good deal? Is this a trusted seller? Is this too good to be true?
