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
Max
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.
Min
Max
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.

1.5 Carat Diamonds

A 1.5 carat diamond is often considered the ideal middle ground for shoppers looking to maximize visual size without stepping into the significantly higher price range of a 2 carat diamond. With approximately 50% more weight than a 1 carat diamond, a well-cut 1.5 carat stone delivers a noticeably larger appearance and greater finger coverage, making it a popular choice for engagement rings and diamond jewelry.

One of the biggest advantages of choosing a 1.5 carat diamond is value. While a 2-carat diamond may only appear modestly larger to the eye, its price can increase substantially due to the rarity of larger diamonds. A 1.5 carat diamond allows shoppers to enjoy an impressive size upgrade while often saving thousands of dollars compared to a similar quality 2 carat stone.

Whether you're shopping for a round, oval, cushion, emerald, or pear-shaped diamond, a 1.5 carat diamond offers a beautiful combination of brilliance, presence, and affordability. Browse our collection and compare diamond prices transparently to find the best value for your budget without compromising on the look you want.

All our diamonds are certified by either the AGS or GIA – the two most respected independent grading labs in the world. Compare diamonds side by side, view detailed grading information and find the perfect stone to create a breathtaking engagement ring that reflects your style and budget.
