Obviously the diamond is the most important component of your diamond engagement ring.
Diamond is one of the four natural forms of carbon, much like graphite (for pencils). Diamond is the hardest natural material.
The value of diamonds for diamond jewellery is often estimated using the 4 Cs: carat, colour, clarity and cut. You will also find these 4 Cs stated on the diamond certificate that is normally offered with each diamond of at least 0.30 ct.

For a diamond engagement ring you should choose diamonds with a good price/quality ratio. In other words, diamonds with a beautiful white colour, such a G or H colour grading, good purity (between VVS2 and SI1) and a very good cut quality (VG cut or better). You can of course opt for higher qualities, but then you invest primarily in value rather than in the obvious beauty of the diamond engagement ring.
Besides diamonds, other precious metals can be used in the manufacture of diamond and other engagement rings. The most durable materials are gold and platinum, but silver and other materials can also be used in combination with diamonds.
