Most common diamond cuts
Diamonds are cut by humans and we have been experimenting with what looks beautiful and what is good for shine and brilliance of diamonds. Most common diamond cuts are Round cut diamond, Emerald cut diamond, Baguette cut diamond and Radiant cut diamonds.
Selection of this cut influences how it looks in certain diamond engagement ring or diamond wedding ring. What works and looks beautiful in certain ring, necklace or earring does not necessarily look as amazing in a bracelet design. It is all about the complete look and feel and not just diamond cuts. Most common diamond cuts are shown in the picture below.
Common ring settings
Remember we discussed it is all about the complete look? Rings especially engagement rings and wedding rings with diamonds are traditionally placed in certain settings which ensures that the stone whether it is a diamond or any other gemstone does not fall but also radiates the feel and looks as amazing as possible.
The selection of ring setting also applied to earrings, necklaces and bracelets and should be decided on what you think will be perfect for your jewelry.
