MiaDonna is the world's first Lab Grown Diamond Store

That means we're experts in lab-grown precious stones! Lab-grown gemstones are the stunning, ethical and affordable alternative to earth-mined gems. By recreating the earth’s natural process in a controlled lab environment, we are able to create Rubies, Emeralds, Alexandrites, and Sapphires that are of higher quality and more beautiful than most earth-mined equivalents. With a lab created gemstone, you get a show-stopping center stone without worrying about negatively affecting the environment or humanity.

Are lab created gemstones real gems?

Absolutely. Just like lab-grown diamonds, our gems are 100% real! Our laboratory techniques produce REAL Rubies, Sapphires, Emeralds, and Alexandrites that are chemically, physically, and optically identical to earth-mined gemstones, but the best part is they are up to 90% less.

How are lab grown gems created?

MiaDonna offers the most technologically advanced lab-grown gemstones from Chatham. Chatham creates their high-quality gemstones using a single growing method called Flux Fusion. During the growing period (six months to a year) the chamber’s temperature and chemistry are carefully controlled to duplicate the environment in the area of the earth where that gemstone variety forms. Over time the crystal begins to grow on the ‘seed’ in its natural crystal shape. Since foreign materials found in the earth are eliminated from a starting ‘seed’, the crystal grows more predictably, which in turn consistently produces the best qualities and colors— even better than those found in nature. Once this process is finished, the outcome is a rough crystal identical to one found in nature which results in the highest quality lab grown gemstones available.

What makes MiaDonna Gems better than others?

MiaDonna lab-grown gems are simply better. All of our Sapphires, Rubies, Emeralds, and Alexandrites are created using the Flux Fusion method which generates optimal brilliance and light return for the highest quality gems.

Sapphires

Sapphires are associated with blessings, divine knowledge, sincerity, and faithfulness. They are also the birthstone for September and the gem of the 5th and 45th anniversaries.

While all colors of Sapphire are beautiful, the most popular color, especially for engagement rings, is blue. Blue Sapphire is the most difficult gem crystal to grow. Color in Sapphire often follows the crystal structure in color zones. Even the best Sapphire crystal has different shades of blue in it. That’s why lab grown blue Sapphires come in three lovely shades of blue, not just one. The price difference between the finest lab-grown and mined Sapphire of the same size and quality can be as much as $10,000 USD per carat!

Padparadscha

The rarest color of Sapphire, Padparadscha is the September birthstone, and used as the 5th and 45th anniversary gem.

True Padparadscha Sapphires are very rare in nature— most jewelers have never even seen one! Growing Padparadscha Sapphire crystals takes a lengthy process of about six months. The result is a beautiful range of orange-pink to red-orange colors, sometimes referred to as “sunrise and sunset” colors.

Rubies

Rubies are associated with intense passion, good luck, protection from misfortune, and personal inspiration. Ruby is the birthstone for July and the gem for the 15th and 40th anniversaries.

Fine Rubies glow like coals, with red fluorescence making them particularly vivid in sunlight. Rubies are very rare: it’s almost impossible to mine flawless Rubies and many mined Rubies are enhanced with heat and fracture filling to improve their appearance. Natural Rubies can command the highest per-carat price of any colored stone. This makes the Ruby one of the most important gems in the colored stone market.

Emeralds

As the gem of spring, Emerald is the perfect choice as the birthstone for the month of May. It’s also the gem of the 20th and 35th wedding anniversaries.

Emeralds are fascinating gemstones made from a mineral called Beryl. They have the most beautiful and most intense radiant green color. It takes about a year from start to finish to grow an Emerald crystal: the crystals grow for about nine months. The controlled environment is rich in chromium to give the crystals a rich green hue, and allows them to grow larger and cleaner than the Emeralds grown in nature. Emeralds are at least twenty times more rare than diamonds, and in the finest grades they can sell for approximately the same per-carat price as earth-mined diamonds. Our lab grown Emeralds are identical to the finest grade earth-mined Emerald but are 3% the cost at only $395 USD per carat.

Alexandrite

Alexandrite is a birthstone for June and is also the gem for the 45th and 55th wedding anniversary.

Alexandrite is the very rare color-change variety of the mineral chrysoberyl and is often described as “emerald by day, ruby by night,” because it changes color from bluish-green in fluorescent light to brownish or purplish-red in incandescent light. Originally discovered in Russia’s Ural Mountains in the 1830s, it’s now found in Sri Lanka, East Africa, and Brazil. This fine gemstone is exceptionally rare and valuable because it is no longer being mined.

The Alexandrites we grow are true laboratory-grown Alexandrite, the famous color-change chrysoberyl variety with the exact same properties as the mined gems. Some suppliers sell a chemically treated color-change synthetic Sapphire as “lab grown Alexandrite.” It isn’t Alexandrite and doesn’t look like the real thing, due to only a slight color change from blue to purple. If you see “Alexandrite” that doesn’t change from green to red, you’ll know that it is just an inexpensive imitation.

Pick your Alexandrite.
