diamond guide

There's nothing quite like the fiery, eye-catching brilliance of a diamond. These days, however, there are a variety of stunning options in addition to natural, mined gems. Whether you prefer the rarity and romance of a traditional diamond or the modern appeal of a lab grown diamond, the following diamond guide provides key details to help you make the best purchasing decision for you.

natural diamond education

Considered one of nature's miracles, natural diamonds formed within the earth under intense pressure and heat. From size and cut to color and clarity, natural diamonds have distinctive qualities that produce their one-of-a-kind brilliance and sparkle. It's important to understand each of these traits when shopping for engagement rings or fine jewelry.

the 4cs of diamonds

The 4Cs of diamonds are key characteristics used to assess a diamond's quality. With any diamond (both natural and lab grown), cut, color, clarity and carat weight all work in concert to determine beauty and value. Essentially, the 4Cs are how gemologists assess and measure the excellence of a diamond.

moissanite vs. diamonds

If you're looking for a beautiful, cost-effective option for your engagement ring or other fine jewelry, moissanite is another wonderful choice. While they may first appear similar to diamonds in appearance and color, these dramatic lab created gemstones are actually made of silicon carbide and offer eye-catching sparkle.

lab grown diamonds vs. cubic zirconia

An inexpensive diamond simulant, cubic zirconia has inferior refractive qualities compared to lab grown diamonds. It’s also not a diamond at all, unlike lab grown diamonds, which are structurally and optically identically to natural diamonds.

are lab grown diamonds flawless?

To the naked eye, a lab grown diamond is indistinguishable from a natural diamond. Just like with natural diamonds, however, there will be inevitable inclusions and flaws in most lab grown diamonds. The 4Cs (cut, color, clarity, and carat weight) are used to determine the value of lab grown diamonds, just as they are with their natural counterparts.

do lab grown diamonds pass a diamond test?

Since diamonds are heat conductors, experts typically check their authenticity with special heat-resistance testers. Do lab grown diamonds pass the test? The answer is more complicated than you might think.

natural or lab grown diamonds?

Chemically, optically and structurally identical to traditional natural diamonds, lab grown diamonds are becoming increasingly popular for their stunning quality and incredible price tag. Lab grown diamonds are real diamonds, are indistinguishable from natural diamonds and can give you a bigger diamond for less than its natural diamond counterpart.

frequently asked questions

Also known as diamond simulants, simulated diamonds like cubic zirconia (which is not a diamond at all) are made to resemble real diamonds but don’t actually share the same chemical, physical or optical characteristics. Lab grown are not diamond simulants.
