Platinum Princess Cut Engagement Rings

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.

Lab Grown and Natural Diamonds

To complete your engagement ring, choose from our large selection of certified natural and lab grown diamonds. Whether you are looking for a 1 carat diamond or a 5 carat diamond, you are sure to find something that matches your expectations. Save 40% or more by choosing from our lab grown diamond collections.
