Story
The marquise cut has a romantic story. In 18th-century France, King Louis XV asked a jeweler to design a diamond shaped like the lips of the woman he loved. That is how the marquise diamond was born.
With its long oval form and pointed ends, the marquise cut makes the diamond look larger than its weight and adds a graceful, elegant style. The 1-carat diamond in this Tiffany ring shines brightly and also makes the finger look longer. It is a classic engagement ring, full of romance and beauty.

A lab-grown diamond is a diamond created in a controlled laboratory environment using advanced technology such as CVD or HPHT. It has the same chemical composition, crystal structure, and physical properties as a natural diamond, but is formed above ground.
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds have the same hardness, refractive index, brilliance, and fire as natural diamonds. They are genuine diamonds in every way.
What is the difference between a lab-grown diamond and a natural diamond?
There is no difference in appearance or composition. The key differences are that lab-grown diamonds are more environmentally friendly, ethically sourced, and generally cost 30–50% less than natural diamonds of the same quality.
Are lab-grown diamonds suitable for engagement rings?
Absolutely. Lab-grown diamonds have the same beauty and durability as natural diamonds, making them an excellent choice for engagement rings.
