Shape
Shape influences the personality and price of a diamond.

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.

1 Carat Lab Grown Diamonds by Ritani

Carat Weight

Ideal for most jewelry settings, 1-carat lab-grown diamonds are a versatile and distinctive size choice that complements every hand. They are a favored choice for engagement rings due to their fine balance of elegance and affordability. For those interested in creating the appearance of a larger diamond, we recommend a halo setting. With a halo setting, the center diamond is lined with a band of accent diamonds, enhancing its size and sparkle power.

All Ritani lab-grown diamonds are certified by International Gemological Institute, (IGI) the most respected independent lab diamond grading laboratory.

Lab Grown Diamonds

Lab grown diamonds are real diamonds that are created in the lab instead of deep inside the earth's crust. They are physically, chemically, and visually identical to earth grown diamonds and are indistinguishable even by a trained gemologist.

The only difference between lab grown diamonds and earth grown diamonds is how they were created. Earth grown diamonds are created under high pressure and temperature deep under the earth's surface, while lab grown diamonds are created under high pressure and temperature(HPHT) in a lab

Lab grown diamonds are typically between 30 and 50 percent cheaper than earth grown diamonds! Therefore they have become a very popular choice for engagement ring, since you can get a bigger size diamond for your budget.

All Ritani lab grown diamonds are certified. Most of our lab grown diamonds are certified by IGI, the most respected independent lab diamond grading laboratory.
