Diamonds & Gems FAQs

Everything you need to know about our diamonds and gemstones, all in one place.

What are the 4C’s of diamonds?

The 4 C’s of diamonds are Color, Cut, Clarity, and Carat. Color refers to how white a diamond is on a scale of D-Z. Cut refers to the exact proportions, quality of polish and the arrangement of a diamond’s facets. Clarity refers to the presence of inclusions in a diamond. Carat weight is a measurement of a diamond’s weight.

What are the different types of diamond shapes?

There are several different diamond shapes and cuts, some that are probably still being invented as you read this. The most popular diamond shapes and cuts available at Lauren B include Oval Shapes, Radiant Cuts, Antique and Modified Cushion Cuts, Round Brilliants, Emerald Cuts, and Pear Shapes. After that come Marquise Cuts, Asscher Cuts, Princess Cuts, Heart Shapes, and Hybrid Step-Cuts. You can learn more about what makes each shape unique here.

Are Lauren B diamonds ethically sourced?

All of our diamonds are conflict free, based upon our personal knowledge and the information provided to us by our suppliers who follow the Kimberley Process. We will always strive to uphold the legitimacy of the diamond trade and disclose the source of all our gemstones.

How are lab-grown diamonds created?

The two processes in which diamonds are formed in a lab are Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT). Both processes can take the diamond up to 12 weeks to form. To learn more about each process, you can read our blog, An In Depth Look at CVD vs. HPHT.

Can you tell the difference between a natural and lab-grown diamond?

Contrary to popular belief, no one can tell the difference between a natural and lab-grown diamond just by looking at it with the naked eye. Only a trained gemologist can tell the difference between the two diamonds by using a loupe or a special diamond tester.

Are the same cuts available for both natural and lab-grown diamonds?

Yes! All natural and lab created diamonds can be cut the same. However, some cuts are harder to find in natural diamonds than lab diamonds because they require more rough diamond to be cut. Due to this, diamond cutters will oftentimes refuse to cut these shapes so as not to waste rough, natural diamond.

Can diamonds get scratched?

Diamonds are the toughest mineral on Earth, ranking at 10 on the Mohs Hardness Scale. They are the most durable gemstone which is why they are the best center stone option for everyday jewelry and engagement rings. The only other object that can scratch a diamond is another diamond. However, this does not mean that diamonds are indestructible and we recommend airing on the side of caution with all diamond jewelry.

Are loose diamonds safe to buy online?

Yes, if you have the right information. Look for detailed diamond specs, independent grading reports from reputable labs like GIA and VeraLume™, clear photos, and videos. At Lauren B, our exclusive loose diamond collection includes on-hand videos, detailed charts, and the option to view or purchase directly from our website. Once you’re ready, a design consultant will guide you and provide any additional images or videos you request.

Can Lauren B arrange my loose diamond in a custom setting ring?

Of course! However we do have a small setting fee for outside diamonds, similar to a “corkage fee”: diamonds under 3 carats are $300 to set and diamonds over 3 carats are $400 to set.

Does Lauren B provide a GIA report for their diamonds?

Yes; all of our natural diamonds come with a GIA report, and most of our lab-grown diamonds do as well. In addition to GIA, a select number of lab-grown diamonds also include VeraLume™ reports. You can preview each diamond’s available grading report directly on its product page before purchase.

Are diamond carat and diamond size the same thing?

Diamond carat and diamond size are related but they are not the exact same; carat is not a measure of a diamond’s size but, rather a measure of a diamond’s weight. To determine a diamond’s actual size, we also look carefully at its spread or measurements. This is measured in millimeters and tells how large or small the diamond appears face up in relation to its weight.

Does Lauren B sell other types of gemstones?

Yes, our loose stone inventory carries Moissanite and a range of color gemstones while our showcases have hundreds of Moissanite and color gemstone rings.

What is VeraLume™?

VeraLume™ is an advanced grading system for select lab-grown diamonds that goes beyond the traditional 4Cs by evaluating Color Tone, Growth Lines, and Visual Performance.

Do all Lauren B lab-grown diamonds include VeraLume™ grading?

VeraLume™ grading is available on select lab-grown diamonds that meet strict criteria, giving clients the option for enhanced transparency when choosing a diamond

What makes VeraLume™ grading different?

Unlike traditional reports that focus only on the 4Cs, VeraLume™ also discloses undertones, internal growth patterns, and face-up beauty. This ensures a clearer picture of each diamond’s true character.
