This modern take on classic diamond cuts stands out when set in rings, necklaces, earrings and bracelets. Our selection of princess-cut lab-grown diamonds offers a stylish, contemporary appeal minus the hefty price tag.

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%.
Min

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.
Min
Max
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 Princess Cut Lab Grown Diamond can cost anywhere between $120 and $23,000 depending on the 4 cs. The median price is $2,500.

Princess cut diamonds fit well with a variety of settings, including solitaire, halo, and three-stone designs. To protect the corners, which are more prone to chipping, consider settings with V-shaped prongs or a bezel setting that encases the diamond's edges.

Caring for a princess cut lab-grown diamond involves regular cleaning with a soft brush and mild soap to remove any buildup of dirt and oils. It's also wise to have it inspected by a professional jeweler periodically to ensure the setting remains secure, especially given the diamond's sharp corners. Avoid exposing your diamond jewelry to harsh chemicals or physical impacts that could damage the stone.

A princess cut lab-grown diamond is a square or rectangular-shaped diamond with sharp corners and numerous facets that maximize the stone's brilliance. It's one of the most popular cuts for engagement rings and other fine jewelry. Lab-grown princess diamonds are created in controlled laboratory conditions, offering an ethical and more affordable alternative to mined diamonds, without sacrificing quality or beauty.
