1.25 Carat Oval Cut Lab Grown Diamond Engagement Rings in Platinum

Carat Weight

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

Shape

Oval cut diamonds have a sparkling, brilliant facet pattern and an elongated silhouette. Developed by Lazare Kaplan in the 1960s, the oval cut diamond is a hybrid of the round brilliant and marquise shapes. 3.2% of all Ritani diamonds sold are oval cut. They are a stunning choice for those who love sparkle but are looking for a slightly more unusual style.

Oval diamonds have become increasingly popular in recent years for engagement rings. Stars who have worn the oval cut diamond include Blake Lively and Hailey Bieber.

Oval diamonds are also a great choice for custom jewelry, such as pendants and earrings. There are some benefits to oval diamonds: they create the appearance of a longer, slimmer finger when worn in an engagement ring, and they also appear bigger than they really are due to their larger surface area. To make your oval diamond appear larger, choose a halo setting. Or let your oval diamond stand out in a solitaire setting.

Oval diamonds will come in varying length to width ratios. They tend to look the most appealing between 1.30-1.50. An oval with a length to width ratio of 1.30 will appear rounder, while an oval with a length to width ratio of 1.50 will appear more slender and elongated.

Metal

Platinum is a very popular choice for engagement rings. Platinum is a white metal that is also extremely durable. Because platinum is too soft in it's pure form to be used for jewelry, it is usually combined with a small percentage of other metal alloys such as cobalt, iridium, ruthenium, or palladium.

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.
