What are Lab-Grown Diamonds?

Lab-grown diamonds, also known as lab-created diamonds, man-made diamonds, or synthetic diamonds, are diamonds that are manufactured in a laboratory. Lab-grown diamonds have the same chemical, optical and physical properties as natural diamonds. Lab-grown diamonds are created using two different methods: high pressure and high temperature (HPHT) or chemical vapor deposition (CVD). HPHT lab-grown diamonds are created through the process of applying high pressure and high temperature to a small carbon seed. CVD lab-grown diamonds are created by placing a small diamond seed in a chamber where it is subjected to hydrogen and methane, which is then ionized to break down the molecular bonds thus causing a pure carbon atom to attach itself to the seed. As the carbon builds, it forms an atomic bond with the diamond seed, thus growing the diamond.
Lab-grown diamonds are real diamonds with the same hardness, optical properties, and chemical composition as natural diamonds.

Benefits of Lab-Grown Diamonds

Lab-grown diamonds have many benefits over natural diamonds.

  • Lab-grown diamonds are ethically produced because they are not mined from the earth. All lab-grown diamonds are conflict-free.
  • Lab-grown diamonds are less expensive than natural diamonds because there is an infinite amount of lab-grown diamonds that can be created.
Where to Buy Lab Grown Diamonds

Lab-grown diamonds are available through many different retailers. Lauren B Jewelry in New York City offers a large selection of lab-grown diamonds in-store located on 44 East 46th Street in New York, NY and online.

Are you ready to say forever? When it's time to select that heirloom piece of jewelry, natural diamonds are the popular choice. If you have questions regarding the benefits of natural diamonds over other types of stones, we have the answers you seek.

What Is a Natural Diamond?

Natural diamonds are those formed by nature. It takes billions of years for natural diamonds to form from heat and pressure deep within the earth. For this reason, this type of diamond is usually the most sought-after. Nothing says 'cherished' like a natural diamond, meticulously cut to perfection and placed in an exquisite setting.

Why Are Natural Diamonds so Envied?

Both types of natural diamonds -- diamonds that have been set into jewelry and loose diamonds -- fetch the highest prices because they're unique, one-of-a-kind stones that have been crafted by Mother Nature herself. While lab-created diamonds are a close second, there's something very special involved in choosing a natural diamond to celebrate your special day. Whether it's set in a classic engagement ring, a sparkling bracelet, or a matched set of pendant and earrings, everyone loves a natural diamond and the infinite amount of time that goes into its creation.

Where to Buy Natural Diamonds

You'll find a superior selection of natural diamonds at Lauren B Jewelry, at 44 East 46th Street in New York, NY. Choose from a carefully curated collection of fine jewelry, or select your own natural loose diamonds to create pieces that are unique to you.

Searching for more affordable jewelry? Consider Moissanite. Moissanite is highly comparable to natural diamonds, but with its own unique characteristics that make it a beautiful and affordable choice for engagement rings, wedding bands, and fine jewelry.

What is Moissanite?

Moissanite was originally discovered in the 1800s by a French chemist named Henri Moissan, hence the name. Moissan found his sparkling gem in a crater left by a meteorite, which makes it truly rare and remarkable. Natural Moissanite is incredibly rare thus the majority of Moissanite jewelry uses lab-grown Moissanite. Still, Moissanite appears much like a natural or lab-grown diamond. This makes it an affordable-yet-stunning alternative to more expensive stones.

Is Moissanite a Good Investment?

Moissanite is a beautiful investment in more ways than one; Moissanite is ranked a 9.25 on the Mohs Hardness Scale. For reference, diamonds are ranked at 10 thus making Moissanite one of the hardest minerals on Earth. Although it refracts light differently than natural diamonds, this can be seen as a plus; those who appreciate pretty rainbow hues may prefer Moissanite because of its higher refractive index. This gives it a more intense and 'fiery' rainbow appearance that emanates flashes of color under strong sunlight.

Where to Buy Moissanite Jewelry

To see a gorgeous selection of Moissanite, visit Lauren B Jewelry in New York. Lauren B Jewelry offers many jewelry pieces with Moissanite, natural, and/or lab-created diamonds to delight every buyer. Choose the stone you prefer and customize your own, unique piece or purchase our in-stock and ready to buy collection of rings and other jewelry. Visit Lauren B Jewelry, at 44 East 46th Street New York, NY, today.

While a diamond will always signify a serious commitment, color gemstones can be a great replacement, addition, or sign of a deeper connection. If you're searching for a colorful gemstone bracelet, pendant, or ring to match your vivacious personality, Lauren B Jewelry, in New York, offers an exquisite selection.

Color Gemstones Are Diverse and Intriguing

From the passionate red of a ruby to the rich, deep hues of a sapphire, everyone enjoys a little splash of color. Regardless of one’s personality, there's a gemstone to compliment you. Choose from our endless collection of loose gemstones to create your own stunning piece. Popular choices include:


The beautiful, soft purple hues of the amethyst have long symbolized peace, calmness, and tranquility. The earliest Romans carved sacred images into amethyst, creating intaglios that still exist today.


Sapphires come in a range of deep, lovely hues, including pink, yellow, blue, and many other colors. These rich stones are reputed to bring harmony into the lives of those who wear them and are often a classic choice for anniversary jewelry.


It was said Cleopatra loved emeralds, associating them forever with royalty. Today, roughly half of the world's diamonds come from Colombia. They symbolize the values of truth, honesty, and eternal youth.

What Is a Cushion Cut?

This diamond shape is an enduring favorite and was considered the go-to cut during the 19th and early 20th centuries. The cushion cut offers the contemporary appeal of a square or rectangle with softer, rounded edges for a more delicate look. Cushion cuts remain popular today because the facets successfully hide imperfections and lower color standards.

What Makes a Cushion Cut Antique?

Since lab-grown diamonds are being made today, the name “antique cushion” can be confusing. In this case, “antique” refers to the cut rather than the age of the stone. The style is similar to the old mine cut used in the 1800s, which featured a high crown, a small table, and large facets. The deep pavilion and larger culet would help the diamond sparkle in candlelight.

While the antique cushion cut isn’t as brilliant as more modern brilliant cushion cuts, the facets produce more colorful fire. This makes antique cuts highly desirable among those who love a vintage look.

How Are Cushion Cut Diamonds Graded?

The GIA® grades all diamonds based on color and clarity. Modified styles, including the antique cushion, are not graded on their cut. Here’s how our antique cushion cut diamonds stack up:

  • Color: All Lauren B diamonds are graded D through J, meaning they are colorless or near colorless
  • Clarity: Most Lauren B diamonds are graded IF (Internally Flawless) to SI1 (Included), meaning any imperfections cannot be seen by the naked eye
