Read on to learn more about this gemstone, including its appearance and cost. Also, discover the different shapes and sizes it can be found in.

Synthetic chrysoberyl var. alexandrite

A rare green variety of chrysoberyl, alexandrite has a unique color changing property. When illuminated in sunlight or incandescent light, it changes from strawberry red to dark pink. The reason for this remarkable color change is the presence of certain impurities. However, these impurities are not found in many natural alexandrite crystals, so it’s important to be cautious when evaluating these stones.

The difference between natural and synthetic chrysoberyl lies in its content of Cr and V. Natural chrysoberyl, which comes from four different sources, has the highest Cr content and lowest V. Both types show a tabular habit, with pinacoids dominating the crystal structure. The most common natural chrysoberyl specimens are found in Tunduru and the Siberian mountains.

The mineral chrysoberyl is a form of quartz with parallel fibrous crystals of various minerals. This property allows them to reflect light across their polished surfaces. This phenomenon is known as chatoyancy. Chrysoberyl is found in granite pegmatites, marbles, gneisses, and mica schists. Crystals often weather out of parent rock, and are found in stream beds and gravel beds.

A true synthetic alexandrite crystal was first grown in 1973 by a U.S. company. Since then, several firms began marketing synthetic alexandrite. Several different methods were used to create many artificial alexandrite crystals, including Morion Synthetic Alex, marketed by Judith Osmer of Ramaura Ruby fame. These synthetic crystals often look as real as the finest natural alexandrite.

Inamori, a synthetic alexandrite, showed a dramatic color change in fluorescent lighting. The color change was attributed to the chromium ions absorbing ultraviolet light. They then jump to higher energy levels and release excess energy as light. Synthetic alexandrite is a rare gem, and it’s often extremely expensive. There are two main methods to produce synthetic alexandrite.

A good quality alexandrite comes from the Ural Mountains in Russia. However, there are newer finds of gem-quality material from South America and East Africa. Typically, the color change of alexandrite ranges from green to yellow to blue green, but it’s possible to find gemstones of a different color combination. It’s rare to find a gem of this quality in a natural gemstone, but synthetic alexandrite closely resembles natural alexandrite.

Color-shifting gemstone

Alexandrite is a type of fine gemstone valued for its magnificent color. It was discovered in the mountains of Russia in 1830 and named after the young Czar Alexander II. Today, the finest natural Alexandrite comes from this region. But the creation of lab-grown Alexandrite by Chatham Laboratories has enabled this precious gemstone to be found in jewelry at affordable prices. Chatham Created Alexandrite offers the same color-shifting properties as natural Alexandrite, but without the high price tag.

Natural alexandrite is rare, but artificially-created gemstones are widely available. This gemstone is a rare form of chrysoberyl and falls in the 8.5 Mohs hardness scale. It is durable and eye-clean. But perhaps its most impressive characteristic is its ability to display the colors of the rainbow. While natural alexandrites exhibit vivid green color changes in different angles, synthetic alexandrite displays blue-green and purple colors.

Lab-created Alexandrites are incredibly beautiful and have the best color-changing properties of any alexandrite on the market. Chatham creates alexandrites from a seed of Russian alexandrite and adds chromium in a solution to ensure the dramatic color change. In addition, Chatham Created Alexandrites are created in the shape of an oval to ensure the same physical and chemical properties as their natural counterparts.

Despite being extremely rare, Alexandrite has a long history and is widely available today. It was discovered in the Ural Mountains of Russia in 1834. The tsars of Russia found it and popularized it, claiming it was the perfect gemstone to represent the majesty and prominence of the Russian royal family. Currently, Alexandrite is mined in Brazil, Sri Lanka, and East Africa.

It appears purple on the inside but reddish-purple on the outside. Natural alexandrites that show excellent color change are extremely rare and extremely expensive, but lab-grown versions are affordable and look just as good.

Quality and cut are key, and Chatham lab-created alexandrite is among the most beautiful in the world. A high-quality cut and color change are the hallmarks of a Chatham stone. A Chatham gemologist handpicks the top stone from five top-grade alexandrites. This ensures the best possible quality at a reasonable price. The cut and clarity rating of a Chatham stone are comparable to that of a mined stone, so the price is well worth the quality.

If you prefer to purchase a gemstone from a local shop, Chatham sells synthetic alexandrite at prices as much as 50% to 75% less. The price varies according to size, shape, and cutting, and can range from $20 to $250 per carat. During normal business hours, a Chatham alexandrite can be ordered online and is subject to availability. Once you’ve decided on a custom design, the gem will take anywhere from twelve to fifteen business days to be produced. If you need the piece quicker, you can pay an extra service fee.

While the quality of natural alexandrite is not quite as high as synthetic alexandrite, Chatham Created Alexandrites come close to the Russian ideal. These gems start with a seed of alexandrite that was naturally mined in Russia. Chromium is added to the mix, ensuring dramatic color change and the same physical and chemical properties. Chatham Created Alexandrite is a much better alternative to natural alexandrite, but with a much lower price tag.
