    Carat Weight

    1.25 carat diamonds are very popular for engagement rings. They provide a good balance between size and price

    Color

    K color diamonds are in the faint color range on the GIA color scale. These diamonds will have a slight yellow tint to them and will therefore have the cheapest prices. K color diamonds can look great when set in yellow gold since the metal will complement the color of the diamond.

    Lab Grown Diamonds

    Lab grown diamonds are real diamonds that are created in the lab instead of deep inside the earth's crust. They are physically, chemically, and visually identical to earth grown diamonds and are indistinguishable even by a trained gemologist.

    The only difference between lab grown diamonds and earth grown diamonds is how they were created. Earth grown diamonds are created under high pressure and temperature deep under the earth's surface, while lab grown diamonds are created under high pressure and temperature(HPHT) in a lab

    Lab grown diamonds are typically between 30 and 50 percent cheaper than earth grown diamonds! Therefore they have become a very popular choice for engagement ring, since you can get a bigger size diamond for your budget.

    All Ritani lab grown diamonds are certified. Most of our lab grown diamonds are certified by IGI, the most respected independent lab diamond grading labaratory.
