What are Type 2 diamonds?

Type II diamonds are those with a non-detectable amounts of nitrogen. Type IIa diamonds have negligible impurities of any kind, while Type IIb are those with atoms of the element Boron trapped in the carbon lattice. Type IIb diamonds are associated with fancy blue diamonds.

What are the main types of diamonds?

Diamonds are separated into five types: Type Ia, Type Ib, Type 1aB, Type IIa, and Type IIb. The impurities measured are at the atomic level within the crystal lattice of carbon atoms and so, unlike inclusions, require an infrared spectrometer to detect.

Which type of diamond is best?

Flawless is the top grade in the GIA Clarity Grading System.

Diamonds are also classified into five different types depending on their nitrogen atom impurities: Type I: (Type IA diamonds, Type IB diamonds, and Type IAB diamonds) and Type II (Type IIA diamonds, and Type IIB diamonds.) Their nitrogen impurities are measured at the atomic level within the crystal lattice of their makeup. Unlike inclusions, which can sometimes be seen by the naked eye, these impurities require an infrared meter to detect. Because this is high-level industry terminology, you don't have to worry too much about the type of a potential diamond. Your jeweler or gemologist will help you navigate these terms as you shop for a ring.

What is a Diamond?

This beloved engagement ring center stone is a solid form of the element carbon. Its atoms are arranged in a crystal structure called diamond cubic. "Natural diamonds were formed about 100 miles below the earth's surface from one to three billion years ago, making them older than life on earth," says Grant Mobley, Diamond & Industry Expert from the Natural Diamond Council. "They form under rare conditions of extreme heat and pressure inside the earth that causes carbon atoms to crystallize. Millions of years ago, ancient volcanoes blasted toward the surface, trapping diamonds in their lava and bringing them close enough to the surface for us to find."

What is the most common diamond used for engagement rings?

When you think of a "natural diamond," you most likely think of a mined diamond. For years, mined diamonds have been the most common choice for engagement rings and wedding bands. "Mined diamonds form deep in the earth's crust under immense heat and pressure over billions of years before they're recovered by mining operations," explains Madeline Fraser, founder and CEO of Gemist.

How are diamonds made?

The first method, called High Temperature, High Pressure (HTHP), uses presses to mimic the environment found in the earth's crust. A diamond seed is exposed to intense heat and pressure, which forces it to grow into a fully-formed diamond. The second process uses Chemical Vapor Deposition (CVD) to grow a diamond from a hydrocarbon gas mixture.

How long does it take to make a lab grown diamond?

Both of these methods can create a true lab-grown diamond in about two to three weeks —significantly less time than the three billion years it takes to create a mined diamond. After both methods, jewelers cut and polish lab-grown diamonds exactly like they would a mined diamond. And, because it's made of the same carbon makeup, a lab-grown diamond will shine just as bright as a mined diamond.

Where did diamonds originate?

According to the GIA, the earliest diamonds were sourced from water banks in India. The diamond industry we know today, though, began in Africa, where diamonds were discovered in 1866. Over 20 years later, entrepreneur Cecil Rhodes launched De Beers Consolidated Mines in 1888. Then, by 1900, De Beers controlled about 90% of the world's production of rough diamonds. Today, the 50 largest mines account for about 90% of the world's supply of diamonds.

Can you color a blue diamond?

If you have your heart set on a blue diamond or a stone with a pale pink tint, you can still get one that's color-treated to your preference. "Colorless diamonds can be color-treated using several different methods," Mobley explains, adding that any sort of color addition is irreversible. "Color treatment is usually only done to a natural diamond with a color that already caused it to have a lower value than a colorless diamond. Color treatments can sometimes improve the look without lowering the value further."
