She Loved It!

The ring arrived in time for Valentine's day!! When she opened the box, she was speechless and at the same time, tears of joy filled her eyes! She adores this ring! The ring sparkles on her finger. Great investment too!

Just perfect !

I hesitated after reading the other reviews for smaller total carats (1.5-2.5 is actually small in an infinity setting). It's the perfect size, not too small, not too big. It shines like no other mainly because of the cushion-cut. Incredible match in diamond size, color and cut over 19 diamonds. Got a total 4.9carats for a size 7. Best buy I ever made. Well worth the extra bucks over the smaller sizes (round or others). Highly recommended.

Great ring

The ring was very well made and was more than well received. Great prompt service as always.
