3 Carat Round Cut Diamond Sidestone Engagement Rings

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

Round cut diamonds (also called brilliant-cut diamonds) are revered for their classic shape and incredible sparkle. Cut with 58 facets — or 57, if there is no culet — the round shape was designed to produce as much sparkle as possible. As sparkle is what many people are looking for when they buy a diamond, round cuts are immensely popular.

60% of the diamonds in our inventory are round-shaped, making it easy for you to find the right one for your needs. Not only are round cut diamonds the most sparkly, but they are also the most popular diamond shape. However, because they are the most sparkly and the most popular, this makes them the most expensive diamond shape.

Round cut diamonds are perfect for custom jewelry, such as earrings and pendants. To make your round cut diamond appear even larger, choose a halo setting. Or let your round cut diamond stand out on its own in a solitaire setting.

Ring Style

Sidestone engagement rings are one of the most popular setting styles at Ritani. This style features feature smaller diamonds in the band for added artistry and sparkle. Sidestone engagement rings pair beautifully with all diamond shapes, but look especially stunning with emerald-cut diamonds or Asscher-cut diamonds. These step-cut diamond-shapes don't sparkle much, so a diamond sidestone setting will add more sparkle to the ring. There are many different ways in which diamonds can be set into the band of an engagement ring, each creating a different look. French-set diamonds are diamonds that are raised, allowing extra light to enter the stone, and are set with tiny beads of metal. Pavé diamonds look like they are paved into the band and are set with tiny points of metal. Micropavé diamonds are set the same way, but with smaller clusters of diamonds set closer together. Channel-set diamonds are the most secure - they are held within a metal channel.

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.
