Ring is beautiful I absolutely love it ! Would definitely recommend it to anyone looking for such a nice engagement ring ! I can’t tell the difference between my natural diamond engagement ring and this lab grown diamond ring except the very big cost difference :)

Heart Cut Split Shank Lab Grown Diamond Engagement Ring

Absolutely fantastic!

The ring far exceeded my expectations. The diamond has a beautiful sparkle and the yellow gold ring looks flawless. The whole presentation was first class. The laser engraved wooden box really compliments the ring. My wife will love it.

Round Cut Split Shank Lab Grown Diamond Engagement Ring

She said yes!

I have never ordered jewelry online before. When the ring arrived it looked even better than the pictures. Customer service was fantastic. I made a mistake ordering and put the wrong ship to address. They corrected it within hours after I emailed explaining what happened. And most importantly, when I gave this to my beloved and asked for her hand she said yes!
