How to Buy a Loose Diamond

If you’re searching for the perfect loose lab-grown diamond, you’ve come to the right place. But, before you make that purchase, make sure you understand how to choose the best stone from the various places when looking for loose diamonds for sale.

Who Needs Loose Diamonds?

Whether you’re using a setting that has been passed down through generations, or you’re replacing a lost diamond for a 10th-anniversary gift, we understand that there are instances where just a loose diamond is needed.

What is a certified diamond?

When a diamond is certified, it means it has been verified and graded for quality by a 3rd party gem laboratory. The lab will use the 4 c’s to grade the diamond and give its ‘stamp of approval.’ If you’re purchasing a diamond, it’s highly recommended that you only purchase a certified diamond.

How Do They Grade Lab-Grown Diamonds?

Lab-grown diamonds go through the same verification and grading process as mined stones. At Clean Origin, we only partner with independent, internationally recognized laboratories, including GCAL and IGI.

After the diamond is graded, the lab issues a formal report, grading each attribute in detail. A visual “map” of the diamond further illustrates any inclusions or “birthmarks” formed during the diamond’s creation. This report includes a unique identification number and accompanies your diamond. Learn more about our independently certified diamonds here.

What should I look for When I Buy Loose diamonds?

Just like if you were searching for an engagement ring, you’ll use the 4 C’s of diamonds to decide what stone is best for you. Let’s review.


People often confuse diamond shape and diamond cut. Round, oval, and pear are all examples of diamond ‘shapes.’ A diamond’s cut, however, is actually an assessment of the artisan’s skill who plans, maps, and hand cuts the facets on each individual diamond. Our cut scale goes from ‘good’ all the way up to ‘ideal.’


When talking about color in diamonds, it’s actually a reference to the absence of color. The color of a diamond is graded on an alphabetical scale starting at D and ranging all the way down to Z, with D being a colorless diamond and Z being yellow. At Clean Origin, we do not offer any color lower than J. Oftentimes, moving up or down one color is an easy way to save a bit of money for a slight change that would be unnoticeable to a naked, untrained eye.


Clarity measures how many natural inclusions or imperfections are found in a diamond. Since lab-grown diamonds are grown using replication of what happens under the earth’s surface, they still contain varying levels of these ‘blemishes.’ Our diamonds start at SI2 and go up to VVS1.


The most commonly known amongst all ‘C’s,’ carat is the size of the diamond. Size is a large contributor to the price of a diamond. However, if you’re saving 20-40% by going with lab-grown, you could easily purchase a diamond that’s 20-40% larger for your same original budget. We offer a wide variety of carat sizes, starting as small as 0.30.

How much are loose diamonds?

Buying a loose diamond will almost always be less than purchasing a ring since you’re not getting a setting. However, the price, loose or not, will really all depend on the type of diamond and where you purchase it. Buying loose diamonds allows you to design your own engagement ring, and that is something extraordinary.

Save Money With Lab-Grown When You Buy Loose Diamonds

Lab-grown diamonds can be anywhere from 20-40% less than mined diamonds. So if you’re looking to get the absolute best ‘bang for your buck”, you’ll want to start there. You can opt to go big on carat weight or get a nicer setting with all of your savings.

When you go with lab-created diamonds, you get quality diamonds at a fraction of the cost. That way, you can ensure you will get the best value on engagement rings and diamond jewelry. High-quality diamonds that are lab-grown allow you to get the best diamond for the best price.

Know What To Look For in Quality Diamonds

However, even within the man-made companies, there is tons of fluctuation with prices for loose diamonds for sale. You will want to shop around to make sure you get the best price for carat weight when shopping for engagement rings and diamond jewelry.
