✨ Where do they get their diamonds from to make diamonds?

  • The jewelry chain buys the diamonds from Pure Grown Diamonds, a New Jersey company that produces them in Asia. “Grown” diamonds — a term the Diamond Producers Association disputes as misleading — cost consumers 30 to 40 percent less than natural diamonds.

✨ How do they make diamonds?

basicallly it is carbon that is highly compressed and heated over time

✨ How they make colored diamonds?

These diamonds owe their color to a combination of intense pressure and heat. While still buried deep within the earth, these factors cause distortions in the crystal lattice that absorb green light, thus reflecting a pink hue. Ultra-rare red diamonds, which are essentially just deeply colored pink diamonds, have the same cause of color.

For a behind the scenes look at how lab created diamonds are made, we’ve created a series of GIFS illustrating the steps involved in the CVD process.

Diamonds are made up almost entirely of pure carbon. That's why both lab diamonds and mined diamonds have the exact same physical properties.

Are synthetic diamonds real diamonds made?

The man-made diamonds have the same chemical composition as those that are found on the earth’s surface. They have the sparkle, fire, and scintillation as exhibited by organic diamonds. Though they are known as synthetic diamonds, technically they are not as they have the same chemical composition as organic diamonds.

What are argyle diamonds & where are they from?

The unique composition of Argyle diamonds is attributed to a volcanic pipe, commonly known as the Argyle pipe, made of olivine lamproite. Due to an eruption, minerals such as zeolite, micas, kaolinite and clays interacted with the diamonds during their formation. Most Argyle diamonds contain small amounts of nitrogen impurities, but the majority of their color is tied to structural defects of the crystal lattice. Argyle Diamond - Grading Scale
