Yes, lab-created diamonds will pass a diamond tester. Even though they are grown in a laboratory by scientists instead of forming deep within the Earth, lab diamonds are still real diamonds. They have the same chemical composition and optical characteristics as natural diamonds. Expert gemologists cannot visually differentiate between the two. The only way to tell them apart is through specialized equipment that detects subtle variations in trace elements and crystal structure.

No, moissanite is a distinct gemstone from lab-created diamonds, with a different appearance and hardness. We do not offer moissanite in any of our jewelry or engagement rings.

Lab-grown diamonds are created using two main methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). CVD is a more advanced, modern technique that is widely preferred for producing high-quality, authentic diamonds. At Valentina Sarai Diamonds, we exclusively use diamonds grown through the CVD process.

The typical growth time for a 1-carat CVD diamond is about a month, though the exact duration can vary based on the size and conditions of each stone.

The CVD process begins with a small "seed" diamond placed in a specialized chamber, where it is exposed to intense heat. A carbon-rich gas mixture is introduced into the chamber and ionized to break the gas molecules apart. This allows the carbon atoms to bond with the diamond seed, gradually building up layers of pure carbon. As the carbon accumulates, it forms strong atomic bonds with the seed, causing the diamond to grow larger. The result is a new diamond that has the same physical and chemical properties as natural diamonds.

This is the precise method we use to grow all of our lab-grown diamonds, which are the exclusive choice for the center stones in our engagement rings, ensuring exceptional quality and brilliance in every piece.
