MoissaniteBay Lab Grown Moissanite Diamonds Emeralds Rubies and Sapphires

Explore our certified gemstone offerings and let yourself be charmed by our moissanite, lab-grown diamonds, emeralds, rubies, and sapphires. When you buy a lab-grown gem, you do not have to worry about mining, war conflict, as well as ethical and environmental issues. All of our gems are laboratory-grown using cutting-edge scientific methods for optimal brilliance and light return. In addition, our lab-grown gemstones are chemically, physically, and optically identical to the earth-mined ones. Once our gems have been lab-grown, they are faceted and polished by skilled cutters using traditional methods used in mined gemstones.


Born from a meteorite that fell in Arizona over 50,000 years ago, moissanite is a rare and unique gemstone that sets the standard for a new category of sustainable fine jewelry. It was first discovered by the Nobel-Prize winner chemist Dr. Henri Moissan on a meteor crater in 1893. Dr. Moissan identified the crystals as a new mineral known as Silicon Carbide (SiC). Further research proved that Dr. Moissan had discovered one of the rarest materials on earth. For more than a century, the dream of using moissanite on jewelry was impossible until scientists found a method to grow these brilliant crystals in a lab. Today, it is such a good substitute for diamonds that even experienced jewelers cannot easily tell the difference.

Colorless Moissanite

MoissaniteBay is the European Retailer of IceMoissanite gemstones. All our gems are colorless (DEF) and are almost perfect on the 4Cs scale. Our moissanite cannot be distinguished from diamonds with the naked eye. IceMoissanite has 2.4 times more fire and 10% more brilliance and luster than diamonds. With a Mohs Scale hardness of 9.25, our moissanite is harder than emeralds, rubies, and sapphires and second only to diamonds. IceMoissanite is highly resistant to scratching, abrasion, breaking, and chipping.

Colored Moissanite

Fancy color moissanite can be a striking pick for your engagement ring and custom jewelry. As the Original Retailer of IceMoissanite gemstones, we offer fancy color moissanite gemstones in pink, blue, green, yellow, champagne, grey and black – something to suit everyone. Whichever color you choose, the premium quality of IceMoissanite and its durability will ensure that your gemstones will continue to retain their color and luster during everyday wear. Every rough gem is carefully cut to perfection and polished by hand. IceMoissanite's master gemstone cutters select only the best color shades and clarity qualities.

Superior Brilliance

Brilliance is the term used to describe the light return of a gemstone. It is the foundation of IceMoissanite's unparalleled brightness and sparkle. As light hits the gem's surface, a part of it enters the stone, while another part is reflected. IceMoissanite's excellent cut grade means that your precious gem exudes a high degree of both fire and brilliance, attained by its perfectly balanced and symmetrically aligned facets. IceMoissanite is the most brilliant gem on the market today, without a doubt.

Lab Grown Diamonds

The timeless beauty of diamonds has enhanced the most stunning jewelry worn by royalty, entrepreneurs, and iconic film stars. The finest examples of diamonds are famous in their own right. So, it is not surprising that many people aspire to own a diamond for themselves or gift it to a loved one. But a perfect stone may have imperfect origins. Natural diamonds are associated with war conflict and oppression, not to mention the serious concerns about mining practices and their negative environmental impact. For these reasons, many customers choose lab-grown diamonds as an ethical alternative to mined ones. Our lab-grown diamonds have the same chemical composition, crystal structure, optical and physical properties as natural diamonds. Lab-grown diamonds are categorized as either High-Pressure High Temperature (HPHT) diamonds or Chemical Vapor Deposition (CVD) diamonds, depending on their production method.

Lab Grown Emeralds

Emerald, the green variety of Beryl, is the most famous and valuable green gemstone. Its beautiful deep green color, combined with its durability and rarity, make the Emerald one of the most expensive gemstones in the market and one of the most desirable to own. Emeralds receive a grade on a scale ranging from AAA (most valuable) to B (least valuable). All lab-grown emeralds offered by MoissaniteBay have received an AAA grade for their superior quality and the absence of inclusions. Lab-grown emeralds are becoming the preferred choice for gemstone enthusiasts since inclusions are considered flaws in a gemstone. Just like our lab-grown diamonds, our lab-grown emeralds are identical to natural ones in their chemical composition and have a better appearance.

Lab Grown Rubies

Ruby is one of the most recognizable varieties of the corundum mineral species. Natural rubies command the highest per-carat price of any colored gems. From deep pink to bright red, the 'gemstone of passion' is highly sought after by jewelers and celebrities alike. The inclusions and impurities found in natural gems are not present in our lab-grown rubies. Still, our lab-grown rubies possess the same chemical, physical, and optical characteristics as the naturally occurring rubies. This fact makes them seem "too" perfect.

Lab Grown Sapphires

Renowned for its gorgeous deep blue color, the sapphire is a popular gemstone for engagement rings. Blue sapphire belongs to the mineral species corundum. MoissaniteBay's sapphires are grown in a laboratory under controlled and monitored conditions. Since we use no synthetic materials to replace the corundum used to create sapphires, natural and lab-grown sapphires are virtually indistinguishable from one another. In particular, sapphires are corundum minerals, both in nature (mined) and our labs (grown).
