Happily Ever After
Diamonds from every angle

My now fiancé purchased the Karina ring. I spent over a year looking for the perfect ring and even went as far as designing my own with Brilliant Earth and then the Karina showed up on their website one day. The 6 prongs are classic, similarly to the classic Tiffany ring. The claws do not over power the diamond, there are nice diamond hidden accents around all 6 prongs. The pave diamonds are petite on the basket and slightly larger on the ring. The ring itself is very slim which helps to emphasize the size of the diamond. I chose rose gold due to both the warm and cool nature of the color. It can be paired with any other jewelry metal. Not to mention rose gold is not as common; however, becoming increasingly popular. There was some concern about colored prongs reflecting color onto the diamond, I can say if that is the case it is not visible at all. The diamond's color and cut sparkle in the light and look flawless. The ring is comfortable, timeless and sturdy. I'm so in love with the ring and the experience, I definitely recommend the Karina. The only disappointment is the ring came missing a pave stone in the basket. BE is going to fix the ring but it will take 2-3 weeks and who wants to part with their new engagement ring. BE should take time to properly inspect a ring prior to customer pick up. ...Read More
