1.25 Carat Heart Shaped 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

Heart shaped diamonds are the most romantic of all the diamond shapes portraying the universal symbol of love. Due to their complex shape, they are also the hardest to cut. Make sure to look for a heart that is perfectly symmetrical on both sides with a length to width ratio of 1 or close to it.

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.
