Oval Cut Lab Grown Diamonds

Are you eyeing a round-cut diamond but prefer something more unique? An oval-cut lab-grown diamond is the perfect alternative! Defined by its elongated shape, an oval-cut lab-grown diamond ring creates the illusion of a bigger size. Style varies depending on the diamond's cut, but a narrower oval works best when flanked with stones on both sides.

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 Oval Cut Lab Grown Diamond can cost anywhere between $72 and $49,000 depending on the 4 cs. The median price is $1,900.

​An oval cut lab-grown diamond is a type of diamond that has been shaped and polished into an oval form. This cut combines the brilliance and fire of round cut diamonds with a more elongated shape, offering a unique aesthetic. Lab-grown oval diamonds are created in controlled laboratory conditions, using advanced technology to replicate the natural diamond-growing process, offering an ethical and sustainable alternative to mined diamonds.

When selecting an oval cut lab-grown diamond, consider the 4 Cs: Cut, Color, Clarity, and Carat. The quality of the cut is particularly important for oval diamonds to ensure maximum brilliance and symmetry. Look for an oval shape that is well-proportioned, avoiding diamonds that are too elongated or too wide. A length-to-width ratio between 1.3 and 1.5 is generally considered ideal for a classic oval appearance.

​Oval cut diamonds offer several advantages, including the illusion of greater size due to their elongated shape, which can also make the wearer's finger appear longer and slimmer. Oval diamonds are known for their brilliance and are less common than round diamonds, making them a distinctive choice for those seeking both sparkle and uniqueness.


Caring for an oval cut lab-grown diamond involves regular cleaning with a soft brush and mild detergent to remove buildup and maintain its sparkle. It's also advisable to store your diamond jewelry separately to prevent scratches and to have it inspected by a professional jeweler periodically to ensure the setting remains secure and the diamond is in good condition.
