apparently engagement rings say something about the wearer..
Round Cut: Traditionalist
Also known as brilliant-cut, a round diamond symbolizes traditional values. Round wearers appreciate the ring's clean lines and symmetry. It has no beginning, no end and beautifully symbolizes romance! And it reflects more light than any other diamond. Ladies who like round diamonds are trustworthy and team players, but they sometimes lack spontaneity. Avril Lavigne and Christina Aguilera both wear wedding rings with round diamonds. It's the most popular cut! Wedding Prediction: You'll have a lovely, vintage-traditional wedding with pink roses, a white dress, and tea light place card holders.
so .. traditionalist? i guess you will know what to expect for the wedding!
