The experience of looking for a diamond engagement ring should be a very pleasurable and enjoyable process. Just like no one can tell you who you should fall in love with and marry, nobody can tell you what style engagement ring you should purchase. This decision is very personal. The ring is for the woman you love. No one else matters. Just be comfortable with what you buy and where you buy it.
Be careful!! After you read what I have to say about the 4 C's: carat weight, color, clarity and cut, you will know which jewelry stores are being honest with you and which are not. Hopefully you will purchase a diamond from someone you trust.
