I found that this article from Ray magazine did a good job in introducing the various jewelry lines from Bvlgari. I checked out Bvlgari official site and found among the various designs, I would go for B.Zero1.

It has all the key elements of Bvlgari, the central spiral, the Tubogas jewels, the lateral rims as well as the elegant. Besides that, most of the designs are suitable for both men and women, so if you are preparing for a proposal on Valentine’s Day, it’s the ring you should go for.
Frankly, I would love to receive a B.Zero1 on Valentine’s Day, especially the one in pink.

But if it might not be suitable for guys huh?
The blue one will look too sissy on guys
