Carat

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.

Common Questions

Frequently Asked Questions

A Heart Shaped Lab Grown Diamond can cost anywhere between $270 and $34,000 depending on the 4 cs. The median price is $2,100.

​A heart-shaped diamond is a unique and symbolic diamond cut that resembles the shape of a heart. It is considered one of the most romantic diamond shapes available and is a popular choice for engagement rings, anniversary gifts, and special occasions. This cut requires high precision to ensure the symmetry and proportions that define its distinctive look.

The quality of a heart-shaped diamond is determined by the standard 4 Cs: Cut, Color, Clarity, and Carat weight. However, the cut's quality, including its symmetry and proportions, is particularly crucial for heart-shaped diamonds to ensure the shape's beauty and brilliance are maximized.

When choosing a heart-shaped diamond, look for a well-defined outline and a symmetrical appearance. The point should be sharp, and the lobes (the top arches of the heart) should be rounded and even. Additionally, consider the length-to-width ratio; a ratio between 0.85 and 1.00 typically offers a classic heart shape.

Heart-shaped diamonds can vary in price, often depending on the cut quality, color, clarity, and carat weight. They may require more precision in cutting and can result in more waste of the rough diamond, which might make them slightly more expensive than more common cuts like round or princess. However, prices can vary widely based on overall quality.


​Heart-shaped diamonds can be set in a variety of ring settings, including solitaire, halo, and three-stone settings. To protect the pointed tip of the diamond, which is prone to chipping, it's often recommended to choose a setting with a V-shaped prong at the bottom.


​Heart-shaped diamonds are suitable for everyday wear, but it's important to choose a protective setting, especially for engagement rings or other jewelry that will be worn daily. The pointed tip of the heart shape can be vulnerable to chipping, so settings with protective prongs are advisable.
