What Are Lab-Grown Diamonds?

Lab-grown diamonds are genuine diamonds that are grown in laboratories, not in the earth. They have the same chemical and physical properties as natural diamonds, and are classified as "diamonds" by professional institutions.
They are sometimes called "synthetic diamonds," "artificial diamonds," or "lab diamonds," but they all mean the same thing and are essentially the same substance as natural diamonds. I would be happy if you could think of this as the development of genuine diamonds through scientific advances.

The main difference is where they are produced. Natural diamonds are produced deep underground, while lab-grown diamonds are produced on the ground (in a lab). They have the exact same components and characteristics as natural diamonds, except for the environment in which they are produced.

Lab-grown diamonds are "diamonds themselves," with the exact same chemical composition (100% carbon) and crystal structure as real diamonds. On the other hand, moissanite and cubic zirconia (CZ) are imitation stones or simulants made to resemble diamonds, and are completely different minerals.

<Lab-grown diamonds>
Chemical composition: Carbon (C) / Mohs hardness: 10 / Brilliance: Diamond equivalent

<Moissanite>
Chemical composition: Silicon carbide (SiC) / Mohs hardness: 9.25 / Luster: Iridescent

<Cubic zirconia>
Chemical composition: Zirconium oxide (ZrOs) / Mohs hardness: 8-8.5 / Shine: Strong, weaker in dim light

* What is the Mohs scale of hardness?

They are not fake. Unlike cubic zirconia or moissanite, they are "real diamonds" whose structure, hardness, and brilliance all match those of natural diamonds. Many gemological institutions (e.g., IGI and GIA) will issue official certificates.

They are indistinguishable to the naked eye, but can be distinguished under a microscope by looking at special inclusions and growth patterns, which requires specialized laboratory analysis.

Lab-grown diamonds do not require mining or distribution costs and pose little environmental or humanitarian risk. In addition, by operating an online store, we are able to cut labor costs and fixed store costs, allowing us to maintain high quality while offering affordable prices.

Pricing

Of course, that's OK. People choose us for a variety of reasons. We receive support from couples who value ethical choices, people who want to spend money on their honeymoon or wedding, people who want to get the ideal grade or size of their diamond within a budget, and many others who prefer the same diamond at an affordable price.

Please consider this for your wedding ring or engagement ring.

Diamonds over 1 carat come with a certificate. We can also provide a certificate as an option for diamonds under 1 carat to 0.3 carats upon request.

Our lab-grown diamonds come with a certificate issued by a highly reliable grading institution (IGI or GIA), which also includes the 4Cs of carat weight, color, clarity, and cut.

Commitment to quality

Like natural products, lab-grown products are hard and scratch-resistant, but please avoid strong impacts and oily or cosmetic stains. We recommend regular cleaning and inspection.
