Great purchase! Highly recommend!
Color: Yellow Gold, Size: 1 cttw
Love these earrings! They have beautiful brilliance and sparkle AND I feel the setting is relatively substantial. They have a screw on back and the back is not small and flimsy like some earring backs I have seen. I purchased the 1 carat pair and love them. Highly recommend!

Beautiful and timeless!
Color: White Gold, Size: 0.5 cttw, Color: White Gold, Size: 0.5 cttw
The earrings are beautiful. I was hesitant to go with lab grown over natural but the quality of the earrings have genuinely changed my outlook on pab grown diamonds. These were made with 14kt screw on backs and have given me peace of mind. These were purchased to be worn in the 2nd ear piercings. They look stunning next to my natural halo diamond earrings.

Great quality
Color: Yellow Gold, Size: 0.5 cttw
Beautiful earrings, but I would definitely get the largest 1ct option if an adult plans to wear them. The smaller sizes would be perfect special gift for a child.
