Much like how we create our Forever One™ moissanite and Caydia® lab-grown diamonds – our rubies, sapphires, and emeralds are created in a lab using cutting-edge, thermal growing technology.

Our rubies, sapphires, and emeralds are all AAA rated! Precious gemstones use a grading system of AAA-D grade. Unlike mined precious gemstones where flaws are inevitable, lab-grown precious gemstones are created in a completely controlled environment. Closely monitored conditions eliminate the defects seen in mined precious gemstones, such as other minerals and impurities, that can diminish their quality or clarity.

Rubies and Sapphires are rated a 9 on the Mohs scale of hardness and make durable options for everyday wear. Emeralds are slightly softer, rated between a 7.5 - 8 on the Mohs scale.

That depends on their size, quality, and clarity. On average, lab-grown rubies, sapphires, and emeralds are about 30-40% cheaper than mined gemstones. This means you can get higher quality gems, at a lower price!

Not to be confused with simulated gemstones, lab-grown precious gemstones have the same physical, chemical, and optical properties of mined precious gemstones. The only difference is their origin! This sustainable option requires no mining to produce and can be made in just weeks to months, rather than millions of years.

Buying any jewelry online can be an overwhelming and daunting process. At Charles & Colvard, we have eliminated the complexity of shopping for lab grown precious gemstones by only offering the highest color and clarity grade on the market (AAA). When purchasing through Charles and Colvard, you can be confident that you are getting the very best!

Lab-grown precious gemstones are just as hard and durable as mined precious gemstones. Rubies, sapphires, and emeralds make perfect heirloom pieces and with proper attention and care, they’ll last a lifetime.

With a hardness of 9 on the Moh’s scale, rubies are a long-lasting, durable gemstone and make an excellent choice as engagement rings.

Color, cut, clarity and size are the determining factors on the price of a ruby. On average, rubies are less expensive than diamonds, however, large rubies are incredibly rare and command prices that rival diamonds.

Rubies have been one of the most sought-after gemstones for centuries. Also July’s birthstone, they symbolize health, wealth, wisdom, and love.

Quality rubies exhibit a deep red color and have minimal inclusions. Lab grown rubies are made in a controlled environment, which enables optimal growing conditions to produce the highest quality rubies.

Ranking between 7.5 and 8 on the Moh’s scale of hardness, emeralds can last for generations, with proper care. Vibrant green in color and minimal inclusions are top characteristics when choosing an ideal emerald for an engagement ring. We make the search easy – our Made, not Mined™ emeralds are created in a lab and have the highest quality rating possible (AAA).

Not as expensive per carat as a diamond, the price of an emerald depends heavily on the color, cut, clarity and size of the gemstone. Rich color saturation without being too dark are the most desirable features of an emerald and demand higher prices.

The allure of emeralds is nothing new and dates back to ancient Egypt. The soothing green color of an emerald symbolizes honesty, vitality, and renewal – making it a sentimental choice for an engagement ring and perfect for May birthstone jewelry.

Quality emeralds exhibit a vivid green color and minimal inclusions. Mined emeralds often contain many imperfections that can detract from the overall look of the gemstone. Lab grown emeralds have the same chemical, physical and optical properties as a mined emerald. The controlled laboratory environment enables these beautiful gemstones to be created without the inclusions seen in mined emeralds.

With a hardness of 9 on the Moh’s scale, sapphires are a long-lasting, durable gemstone and make an excellent choice as engagement rings. (One of the most famous engagement rings of our time was Princess Diana’s stunning oval sapphire ring.) Deep blue in color, they’re often associated with royalty, protection, and wealth. When considering a sapphire as a romantic and unconventional engagement ring, couples should look for superior cut, color, and clarity. Our Made, not Mined™ sapphires are created in a lab and have the highest quality rating possible (AAA).

Sapphires are not as expensive per carat as a diamond. The price of a sapphire depends heavily on the color, cut, clarity and size of the gemstone. Rich velvety blue to violet-blue tones are most desirable and demand higher prices.

Sapphires have appealed to royalty since the beginning of time and have a long history of having healing properties. The deep blue color is mesmerizing and is even thought to protect wearers against bad energy. As an engagement ring, it’s a timeless and elegant choice. In everyday jewelry, it’s championed for its mysterious depths and equally adored as a September birthstone.

Quality sapphires exhibit a deep “velvety” blue color and minimal inclusions. Mined sapphires often contain many imperfections that can detract from the overall look of the gemstone. The advantage of lab grown sapphires is they have the same chemical, physical, and optical properties as a mined sapphire, but the controlled laboratory environment enables these beautiful gemstones to be created without the inclusions seen in mined sapphires.
