Alexandrite Gemstones

Alexandrite changes colour because of the way its chemical composition interacts with different light sources. Small amounts of chromium within the gemstone influence how it absorbs and transmits light. 

Daylight contains a different balance of wavelengths from warm  lighting, causing alexandrite to display different colours depending on the environment. The effect can range from a subtle shift to a dramatic transformation between green and red. The strength of this colour change is an important factor when assessing the quality of an alexandrite gemstone.

Yes, natural alexandrite is considered a rare gemstone, particularly when it displays a strong colour change, attractive colours and good clarity. Fine-quality stones in larger carat weights are especially uncommon, which contributes to their desirability among gemstone enthusiasts and collectors.

Although alexandrite has been discovered in several countries, finding natural stones with an excellent balance of colour, clarity and colour-changing effect can be challenging. Laboratory-grown alexandrite is also available, offering a different option for those attracted to its distinctive appearance.

Alexandrite can be an excellent choice for engagement rings if you are looking for a distinctive coloured gemstone with a unique appearance. With a Mohs hardness of 8.5, it offers good resistance to scratching and is suitable for many jewellery designs, including rings intended for regular wear.

However, durability also depends on the gemstone's individual characteristics, cut and setting. A protective setting can help reduce the risk of damage from accidental knocks. Regular care and professional checks are recommended to help maintain the gemstone and its setting over time.

Natural alexandrite can command high prices because of its rarity and distinctive colour-changing properties. The value of an alexandrite depends on several factors, including the strength of its colour change, the attractiveness of its green and red colour ranges, clarity, cut, carat weight and, where reliably established, origin.

Larger natural stones with a pronounced colour change are particularly sought after. Laboratory-grown alexandrite is another option and is generally more accessible in terms of price. Comparing these characteristics can help you choose a gemstone that suits your preferences and budget.

Yes, lab grown alexandrite is available and can display the same characteristic colour-changing effect as natural alexandrite. It has essentially the same chemical composition, crystal structure and key optical properties, but it is produced in a controlled laboratory environment rather than forming naturally within the Earth. 

Lab grown gemstones are generally more readily available and can offer an alternative to rare natural gemstones. When purchasing alexandrite, it is important to establish whether the stone is natural or lab grown, as this distinction significantly affects its rarity, value and how it should be described.
