A heart-shaped diamond solitaire ring is one of the best designs for an engagement diamond ring. Giving the heart-shaped diamond ring to your better half is the best way to show that your heart belongs to her now. Here, a heart-shaped diamond is used as the main gemstone, which is secured in a six-prong setting. You can also cluster two pear-shaped diamonds on the crown of the ring as well in order to offer the same look, but for an affordable budget range.
Another design for a solitaire diamond engagement ring features an oval shaped diamond at the center that is secured using a bezel setting. Furthermore, to complement the sturdy appearance and overall look of the gemstone, a moderately thicker shank is used in this design. Usually, platinum or yellow gold is used in a solitaire diamond engagement ring.
