3 Carat Princess Cut Diamond Engagement Rings in Platinum

Carat Weight

3 carat diamonds are bigger than the average engagement ring diamond and are sure to make a statement and impress your significant other. The large size of your diamond will be very noticeable and make it stand out among the others

Shape

Princess cut diamonds are truly distinctive due to their 90-degree angles and sparkling facets. A modified brilliant cut with a square shape, the emphasis with the princess shape is on bold, modern lines, and lots of brilliance. Princess cut diamonds are a beautiful choice for engagement rings, earrings, and pendants.

Although it was only invented in the 1980s, this diamond cut is one of the most popular choices for engagement rings. For a perfectly square princess cut diamond, choose a diamond with a length to width ratio of 1.00 - 1.05.

The sharp corners of princess cut diamonds are prone to chipping, so choose a setting that will protect the diamond’s corners. To make your princess cut diamond appear larger, choose a halo setting, or let it stand out on its own in a solitaire setting.

Metal

Platinum is a very popular choice for engagement rings. Platinum is a white metal that is also extremely durable. Because platinum is too soft in it's pure form to be used for jewelry, it is usually combined with a small percentage of other metal alloys such as cobalt, iridium, ruthenium, or palladium.

Earth Grown Diamonds

Earth grown diamonds are mined from deep under the earth's surface where they have lain dormant for millions of years. When you hold an earth grown diamond, reflect on the immense journey this diamond has taken and the history it has endured.

A diamond starts out in the lowly form of graphite, such as you might find in the tip of your pencil. Over the course of hundereds of millions of years, the immense pressure and temperature produced deep inside the earth rearrange the carbon atoms into a crystal structure.

Then miners dig deep tunnels under the earth and collect the rough diamonds. The rough diamond looks nothing like the sparkly diamond you are holding. It has an irregular shape, is very dirty and looks dull. The diamond is then cleaned, cut into it's desired shape, and finally polished into the beautiful diamond you are now holding!

All Ritani earth grown diamonds are certified by either the AGS or GIA – the two most respected independent grading labs in the world.
