Lab Created Alexandrite : Colour Changing Wonder

The Alexandrite

Jewellers affectionately call alexandrite an “emerald by day and ruby by night” because of how it changes colour in different light conditions. With a bright lustre and incredibly rare colour-changing properties, alexandrite is one of the most desired and valuable gemstones on the planet. 

 

But, you already know getting your hands on high-quality alexandrite is difficult. 

 

Natural stones are harder and harder to come by, and the lab-grown market is just as difficult to navigate with resellers and manufacturers flooding the market with stones that vary in grade, quality and price. 

 

If you get stuck with lab-grown alexandrite that isn’t the right colour or does not provide your desired colour change, you can’t bring your designs to life. Worse, poor-quality stones with pits and blemishes can completely discredit the reputation you worked so hard to build. 

 

So if you want reliable access to top-quality alexandrite and to lead the market with luxury, sustainable jewellery, you’re going to want to learn about how BIRON®’s lab-grown stones can transform your business.

Your current customers will love gaining access to such high-quality, sustainable alexandrite.

 

And you can now attract new customers who increasingly value ethically sourced and sustainable gems. 

 

Available in teal, greenish-blue, or blue-green under natural daylight that changes to purple-red or red under incandescent light, our alexandrite boasts little to no inclusion while maintaining its colour-changing ability.

More About Lab Created Alexandrite

What is an alexandrite?

Alexandrite is made up of a type of mineral known as chrysoberyl and trace elements chromium and beryllium. It is considered rare for its colour change from green to red. It is known as the “emerald by day and ruby by night”.

 

Discovered in the 1830s in the Ural Mountains of Russia, alexandrite is considered exceptionally rare and highly valuable in coloured gemstones when it comes to colour-changing varieties. This gemstone is now also found in Sri Lanka, East Africa, and Brazil and was named after Czar Alexander II who was assassinated in 1881.

 

When viewed under different light sources, alexandrite can shift to green under daylight because the colour is more easily balanced and human eyes are more sensitive to green light. In incandescent light, alexandrite tilts towards the red end of the spectrum. To be considered an alexandrite a colour-change greater than 30% is required.

 

Alexandrite is the birthstone for the month of June and is associated with fifty-fifth anniversaries. This gemstone is available in all shapes but sizes over one carat is rare for natural stones. Oval and cushion are the most prevalent shapes for this stone. Alexandrite is one of the world’s most expensive gems due to its unique quality and difficulty in finding a loose stone in the rough that is ideal for faceting. Alexandrite is usually suitable for cabbing.

What are lab-grown alexandrites?

Created alexandrite is grown in a controlled environment in a laboratory that replicates the same chemical composition as that of its natural counterpart. They can have little to no inclusions and often present as completely clean to the naked eye. They can also differ in colour and saturation. Artificial alexandrite is real and unmined, so is eco-friendly and humane.

 

Natural alexandrite is found in the earth and mined. They are formed without control over conditions and contain different impurities that express different final results in colour, clarity and shape.

 

Their colour-change ability can vastly vary and natural alexandrite is difficult to find in an ideal form in the rough that is suitable for faceting when it comes to gemstone cutting.

What are the benefits of created alexandrite?

Synthetic alexandrite created in a lab has the ability to capture the colour-change alexandrite is known for to varying degrees. It can be bluish-green to reddish-purple to suit individual needs, making it ideal for sourcers and suppliers to meet the demand of retailers, jewellery brands and designers.

 

First grown in 1909, created alexandrite is made with the exact chemical composition of natural alexandrite that contains chromium and beryllium. Alexandrite that is man-made can be made into a clean and facetable version in comparison to its natural counterpart, making it easier to cut and shape while maintaining its unique colour-change and clarity.

 

While reducing carbon footprint and humanely made without being mined, lab-made alexandrite can be created with improved clarity and can have little to no inclusions.

 

This type of manufactured gemstone can also be made larger than one carat, which is considered rare in its natural counterpart, and larger than two to three carats is considered even rarer.

How are artificial alexandrite made?

Artificial alexandrite made in a laboratory can be created using the Crystal Pulling (also known as Czochralski ) method.

 

The melt process involves the chemical composition remaining the same throughout, from start to finish. This method created in the early 1990s involves melting nutrients in a heated container and a seed is dipped into the melt whereby synthetic crystals slowly grow from it as it is gradually pulled away from the melt.

FAQs on Lab Made Alexandrite

Is lab-grown alexandrite real?

Yes. Synthetic alexandrite that is grown in a laboratory is made up of the same chemical composition as its natural counterpart, which includes two natural trace elements chromium and beryllium. This gives the gemstone its colour-changing capability to shift from bluish-green to reddish-purple. Lab-grown alexandrite is real and unmined, and has the same optics and physical properties as a natural alexandrite.

Is lab-created alexandrite valuable?

Yes. Lab-grown alexandrite is valued for its ability to capture the unique colour-change alexandrite is known for. Alexandrite made in a lab can be made into larger carat weights that are rare to find through mining. Synthetic gemstones created through man-made processes can be 100% consistent with naturally-mined gemstones. These gemstones hold a high-quality finish with the clarity required with little to no inclusions at a fraction of the price and have strong roots in eco-sustainability and humanitarianism.

Is lab alexandrite as durable as mined alexandrite?

Yes. Alexandrite grown in a laboratory holds the same durability as that of its natural counterpart. Their chemical, physical and optical properties are identical.

Do manufactured alexandrite contain inclusions?

Synthetic alexandrite is grown in a laboratory that provides a controlled environment to create relatively pure stones. Inclusions can still occur, just fewer than natural alexandrite.

What are the differences between lab, natural and simulated alexandrite?

Lab-grown alexandrite is a real gemstone that holds identical chemical composition, optical and physical characteristics as natural alexandrite. They are real but unmined, can have little to no inclusions and are shaped from lab-grown rough gemstones.

Natural alexandrite grows in the earth naturally and is mined. They are found in the rough and have inclusions or visual variations due to the gemstone’s unpredictable growth process and mineral composition. Unique natural collectible gemstones are available for sale, on our platform.

Simulated alexandrite, also known as imitation, is not the same as lab-grown alexandrite, due to their difference in composition. They are physically and chemically different, constituted of man-made material and can look like a natural or lab-made alexandrite. They can replicate the gemstone’s colour in different chemical compositions such as sapphires coloured by vanadium. Imitation gemstones are significantly cheaper than synthetic or natural gemstones.
