  • Small but mighty sparkler!
Ring Size: 7 Total Diamond Weight: 0.3 carats
This 0.3 ct lab diamond ring set in sterling silver is so beautiful, sparkly and shiny! The stone is small but not microscopic. The band is substantial and feels comfortable on my finger. It stacks beautifully over my plain white gold wedding band. It's perfect for everyday wear. This is an understated beauty at a great price. Love it! ... show more

Ring Size: 8 Total Diamond Weight: 0.3 carats
Beautiful tiny diamond that shines and sparkles. Love how petite looking it is. The packaging came with a large ring box and a mini gift bag for gifting for others.

  • Beautiful Ring
Ring Size: 8 Total Diamond Weight: 0.5 carats
I’m so happy I got this it’s beautiful with an awesome spectrum making it shine. It’s very nicely set and seems durable not being something I’d wear out in garden . The silver looks just like white gold too. It’s a perfect fit to. Then there’s the great packaging I was afraid the package would be small but to my surprise three boxes making it a more secure delivery in my eyes. The silver is non tarnish along with scratch proof which remains to be seen. I’d trust this jeweler for later purchases. Five star item ❤️ ... show more

  • One month wear
Ring Size: 5 Total Diamond Weight: 0.3 carats
Please ignore that it is on my pinky, I have gained weight since birth and did not know my ring size anymore. After 1 month of wear it has not tarnished or scratched. It fits the ring size that was ordered. The diamond itself is small but sparkles very well. It is comfortable
