I love colored diamonds. I think black diamonds are really pretty. I haven't seen any other colored diamonds in real life, only photos.

Blue diamonds have become popular a few years ago. You should be able to see jewelry with them in your usual jewelry stores.
I have seen a pink diamond in a wedding ring. It had a very pretty shade of pink!

SO many cool facts! I have no idea--I'm actually very new to diamonds BUT my bf and I did go look for some rings around the holidays and I wanted to brush up on as many things as possible. That said, I think colored diamonds are beautiful; the pink diamond wedding ring you describe in your comments sounds gorgeous!

Natalia Khon said...

I believe you you still have to go to a jeweller and custom order a wedding ring if you want a good size colored diamond. Regular jewellery stores usually offer standard stones that they know can be sold fast and easy.
