Shape
Shape influences the personality and price of a diamond.
Price
Many factors impact diamond price. With Ritani's Diamond Price Match Guarantee you can be confident you'll get the best price for a diamond. Tip: Tradition tells you to budget 2-3 months' salary for your ring. We say, just do you.
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.

Emerald Cut SI1 Diamonds

Shape

The emerald diamond shape has a large, open table and rectangular step-cut facets, reminiscent of its green gemstone namesake. Emerald cut diamonds are growing in popularity for engagement rings and make a great choice for earrings and diamond necklaces.

As an engagement ring, the emerald cut diamond can create the illusion of elongating your finger. The emerald cut diamond is an incredibly sophisticated choice that evokes Art Deco glamor.

If you’re looking for a sparkly diamond, an emerald cut diamond may not be right for you - the large facets of this shape means that clarity tends to be its defining feature, as opposed to the sparkle of a brilliant cut. However, they do produce flashes of light that create a hall of mirrors effect.

If you are purchasing an emerald cut diamond engagement ring but want to add more sparkle, choose a classic diamond band or a halo setting.

When purchasing an emerald cut diamond, choose a clarity grade of at least VS1. Emerald cut diamonds can be square or rectangular. A length to width ratio of 1.00 – 1.03 is excellent for a square emerald, while a 1.40 – 1.50 is best for a rectangle.

Clarity

undefined diamonds have slight inclusions visible under 10x magnification (SI stands for slightly included). For Emerald Cut diamonds, you might notice some imperfections even to the naked eye. Make sure to look at your diamond's imagery to determine if it's eye clean or chat with a specialist to discuss your diamond.

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.
