What is a lab diamond?

A lab-grown diamond is a marvel of modern science and innovation. Unlike diamond simulants like cubic zirconia or moissanite, lab-grown diamonds are real diamonds; they just have a different origin. Cultivated in controlled laboratory environments, these diamonds possess the same chemical composition, physical characteristics, and dazzling brilliance as natural diamonds, and they are revolutionizing the world of engagement rings.

How Does the Price Compare Between Lab-Grown and Natural Diamonds?

The accessibility of lab-grown diamonds presents an enticing opportunity for individuals to own exquisite diamond jewelry without the premium price tag. While the price difference between lab-grown and natural diamonds is a dynamic landscape subject to fluctuations, it is likely to hold true for some time that a lab-grown diamond of exceptional quality could be acquired at up to a 15th of the price of a natural diamond of comparable quality. The chart below illustrates what that can look like in reality.

Lab vs. natural diamonds:What’s the difference?

Chemically and physically, lab-grown diamonds are identical to natural diamonds, sharing the same remarkable properties of brilliance, durability, and chemical composition. The key difference is how they come into existence: lab-grown diamonds are created under controlled conditions in a laboratory setting, while natural diamonds are formed deep within the earth's mantle over millions of years and mined from the ground. While both options offer unparalleled beauty, lab-grown diamonds present a sustainable alternative that reduces the environmental impact associated with traditional diamond mining, making them an increasingly popular choice for conscientious consumers.

Frequently asked questions

How can you tell a lab-grown diamond from a natural diamond?

Distinguishing between lab-grown and natural diamonds requires the keen eye of a trained gemologist or jeweler, or the use of sophisticated testing equipment in a lab. When viewing lab-grown diamonds through a loupe under 10x magnification, it is clear to see that the girdle is laser inscribed with the words ‘laboratory created’. And using methods such as spectroscopy, gemological experts can observe the unique signatures that differentiate lab-grown diamonds from their natural counterparts.

Why aren’t lab-grown diamonds perfect?

While lab-grown diamonds boast remarkable clarity and brilliance, they are not without imperfections. Despite the controlled laboratory environment, the crystal growth process isn't entirely predictable, leading to occasional imperfections. Fracture lines may form unexpectedly, and variations in crystal size are not uncommon. Factors such as temperature fluctuations or impurities in the growth environment can influence the outcome, resulting in diamonds that may exhibit minor flaws or irregularities. However, these imperfections are inherent to the growth process – just as with natural diamonds – and do not diminish the beauty or durability of lab-grown diamonds.

How does the quality of lab-grown diamonds compare to mined diamonds?

Just like their natural counterparts, lab-grown diamonds exhibit a range of qualities, from breathtaking brilliance to less striking appearances. However, what sets lab-grown diamonds apart is their accessibility. While natural diamonds of comparable quality can command prices significantly higher, lab-grown diamonds offer a more affordable alternative. This means that individuals have a greater likelihood of acquiring a stunning lab-grown diamond at a fraction of the cost of a similar natural diamond.

Where do lab-grown diamonds come from?

The majority of lab-grown diamonds are produced in advanced facilities located across several key regions worldwide. Among these, countries such as the United States, China, India, and Singapore are prominent centers for lab-grown diamond production, with India emerging as the leader in growing and cutting lab diamonds. This global network of facilities ensures a steady supply of high-quality lab-grown diamonds, meeting the growing demand for sustainably-sourced gemstones in the jewelry industry.

How are lab-grown diamonds created?

Lab diamonds are born from a marriage of science and artistry, cultivated through innovative technologies that replicate the natural diamond growth process. By harnessing the power of high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) methods, lab-grown diamonds are nurtured from tiny diamond seeds into exquisite gemstones of incredible beauty and brilliance. Explore more details about how these two methods compare in this article.

How are lab diamonds certified?

For both lab-grown and natural diamonds larger than 4mm in size, independent certification is a standard practice. Accredited gemological laboratories like GIA And IGI meticulously examine each diamond, assessing its cut, color, clarity, and carat weight to generate a comprehensive certification report. However, for diamonds under 4mm in size, certification is typically not pursued within the trade due to the disproportionate cost of certification relative to the diamond's value.

Tori & Aidan: Proposal on the Nā Pali Coast, Kauai

Why we chose K&D: Being an artist with a strong passion for sustainability, it was crucial for me to find a ring that was not only unique but also shared my eco-conscious values. Fortunately, Ken and Dana Designs perfectly aligned with my vision.

When spotting the Carrisa ring, I was immediately enamored with its floral basket design. The intricate details, like the delicate leaves that held the diamond in place made me fall in love even more. Additionally, I opted for a lab-grown diamond for sustainability reasons and K&D provided an abundance of helpful information and resources on their website that reinforced my choice. I am absolutely smitten with my ring and am looking forward to admiring it every single day for the rest of my life.
