Price

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.

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.

Heart Shaped Lab Grown Diamonds by Ritani

Shape

Heart-shaped diamonds are a quintessentially romantic diamond cut designed to exhibit exceptional sparkle. This cut is a modified brilliant diamond shape similar to that of pear-cut diamonds. A heart-shaped diamond can have a standard heart shape or be narrow or wide depending on its length-to-width ratio. Because this diamond cut often displays a bit of color in its point, it is best to select a higher color grade than you would for a round diamond.

Heart-shaped diamonds are a popular choice for center stones in diamond engagement rings, but they also look stunning when used in pendants, bracelets, and earrings. Like other diamond cuts, it is essential to choose the right features when purchasing a heart-shaped diamond. The ideal length-to-width ratio is as close to 1.00 as possible, and the diamond should exhibit perfect symmetry on both sides.

All Ritani lab-grown diamonds are certified by International Gemological Institute, (IGI) the most respected independent lab diamond grading laboratory. If you need help selecting a Heart-Cut Diamond, contact us at 1-888-9RITANI or chat now!

Frequently Asked Questions

  • How much does a Heart Shaped Lab Grown Diamond cost?
    arrow

    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.

  • What is a heart-shaped diamond?
    arrow

    ​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.

  • How is the quality of a heart-shaped diamond determined?
    arrow

    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.

  • What should I look for when choosing a heart-shaped diamond?
    arrow

    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.

  • Are heart-shaped diamonds more expensive than other shapes?
    arrow

    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.


  • Can heart-shaped diamonds be set in any type of ring setting?
    arrow

    ​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.


  • Are heart-shaped diamonds suitable for everyday wear?
    arrow

    ​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.
