Carat
Carat is the measure of a diamond's weight and size. We offer an array of high-quality diamonds ranging from 0.18 to 25.00 carats- with 1.00 carat being the most popular.
Color
A diamond’s color grade actually measures how little color it reflects. To strike the best balance between cost and beauty, go for diamonds in the Near Colorless range: G, H, and I.
Clarity
Clarity indicates how many flaws are visible to the naked eye. Too many flaws can detract from a diamond's beauty.
Cut
Cut is the quality of a diamond’s proportions and symmetry. The better a diamond’s proportions and symmetry, the more sparkle it will produce. Cut is the most important of the 4 Cs.

Polish
A well-polished diamond will have excellent light return.

Fluorescence
Some diamonds glow blue or green when exposed to UV light. Since fluorescence is rarely visible, it has minimal impact on the appearance of your diamond. To save money, go for medium fluorescence.
Depth
Depth percentage correlates with a diamond's sparkle factor. It is measured by dividing the diamond height by its diameter. For maximum sparkle, the depth percentage of a round diamond should be between 54% and 66%.
Length/Width Ratio
The proportional relationship between your diamond’s length and width. A perfect round diamond would measure equally 1-to-1, so its LxW ratio would measure as 1.
Symmetry
Symmetry tells you how well a diamond’s facets align to create sparkle. Diamonds with perfect symmetry create the most sparkle and earn a grade of Excellent or Ideal.
Table
Table percentage tells you how big a diamond’s topmost facet (aka table) is in comparison to its diameter (aka girdle). When that ratio is in the right range, a diamond will sparkle more.
Culet
The culet is the point at the bottom of the diamond. If the point has a facet on it, it can stop light from reflecting and detract from the diamond's sparkle. Choose a diamond with no culet for optimum sparkle.
Certificate
All of Ritani’s natural diamonds are certified by either the GIA or AGSL, the industry’s two most respected grading labs.

3 Carat Radiant Cut Diamonds

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

The radiant cut is a stunning hybrid of other diamond shapes - it resembles the rectangular silhouette and cropped corners of an emerald cut diamond, but with more sparkle.

Radiant cut diamonds have a modified brilliant cut, making their sparkle similar to princess cut diamonds. Radiant cut diamonds currently make up 3.3% of Ritani's diamond sales.

It's a sophisticated choice for those who want a more extraordinary diamond shape, but still with that classic sparkle. The elongated silhouette of radiant cut diamonds will make your diamond appear larger and will make your finger appear longer and more slender.

Stars who have worn radiant cut engagement rings include Jennifer Lopez and Drew Barrymore. Radiant cut diamonds are also a beautiful choice for custom jewelry, such as pendants and earrings.

Radiant cut diamonds are typically rectangular in shape, but they can also be square. For a square radiant cut diamond, choose a stone with a length to width ratio of 1.05 or less. For a rectangular radiant cut diamond, choose a stone with a length to width ratio of 1.20-1.35. Choose a length to width ratio that is appealing to you - there is no correct one.

If you want to add additional sparkle, choose a halo setting. This can also make your diamond appear larger. Or let your radiant cut diamond stand out on its own with a solitaire setting.

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.
