History of the Alexandrite: June's Birthstone


Happy June, everyone! The first signs of summer are now undeniable, and I'm so looking forward to it. Since last month's post on the emerald went over so well, and several of you requested that I make it a series on the birthstones, we are going to learn about June's birthstone today. 

Technically, there are three birthstones listed for June, the pearl, alexandrite, and moonstone. Since the pearl isn't exactly a stone, and moonstone isn't as popular, I picked the alexandrite for our study. 

The alexandrite is a more recently discovered stone, not near as ancient as the emerald. However, it does have a connection to the emerald. The first crystals were discovered around April of 1834 in emerald mines near the Tokovaya river in Russia. In fact, the stones are named after the Russian Tsar, Alexander II. The legends tell that on the day the future Tsar came of age, the stone was discovered in the mine. Its principle colors of red and green are also the principle colors of Imperial Russia, so it was natural that this stone was adopted by Tsarists as their national stone.

According to AJSGem.com, the legend goes like this:

Miners were working alone in the mountains one day, collecting emeralds. One miner gathered some stones, which looked like emeralds and took them back to the camp at the end of the day. But in the light of the campfire, the stones shone a brilliant shade of red! The miners were perplexed. When morning came and they saw that the stones were green again in the light, they realized that they had found a new and mysterious gem.

The beautiful aspect of the alexandrite is its color-changing ability. During the day, under natural light, the gem appears as a bluish-green. However at night, or under florescent light, it appears red or purplish-red. Below is a video with the scientific explanation of how this stone changes color, in contrast to stones like the emerald.

Alexandrite became a favorite among Russian aristocracy, and was highly prized. In France, it also became popular. But it was the American Tiffany Company that truly brought this stone its fame. George Kunz, a master gem buyer for the company, fell so much in love with the stone that he traveled to Russia and purchased unknown amounts of it. He bought so much, that the Tiffany Company had almost a monopoly on the gem for decades.

The original source of alexandrite, in the Ural mountains of Russia, closed after only a few decades of production. For many years, alexandrite was almost impossible to find, and was considered nearly extinct. However, they have found new sources in Sri Lanka, Brazil, Tanzania, and other places, but the colors are not always consistent with the original Russian Alexandrite. Therefore, this stone is still considered a rarity.

If you have a birthday in June, please tell us in the comments below so we can wish you a very happy birthday!

Matthew Maury - Pathfinder of the Seas

With Nancy J. Farrier

Have you ever wondered how scientists discovered the ocean currents, such as the Gulf Stream Current? Who first figured out there were even currents to map out? The answer to those questions would be Matthew Fontaine Maury: oceanographer, astronomer, historian, cartographer, meteorologist and geologist.


Maury was born in 1806 in Virginia, but his family moved to Tennessee when he was five-years-old. He longed to grow up and join the Navy like his older brother. In 1825, he did join the Navy and went to sea. He was fascinated with studying the seas and the ways of navigation on the seas. He also wrote down his findings and published book about navigation.


Memorial at Goshen Pass
The main focus of his life work happened when he was in bed, unable to get up. I am not positive if he’d been injured or was ill near to the point of death, but either way he was bedridden. One of his children would read the Bible to him every day, and one day began to read Psalm 8 to him.


Maury was struck by the words in Psalm 8:8 – “The fowl of the air, and the fish of the sea, and whatsoever passeth through the paths of the seas.” He had this verse read to him over and over as he pondered the idea of “the paths of the seas.” At last he said, “If God says there are paths to the sea I am going to find them if I get our of this bed.”


He recovered, and with the inspiration of the Psalm, began his intense study of the seas and the patterns of their movement. He is considered the father of oceanography. He charted the currents and helped shippers understand the ways of the ocean so they were more successful at crossing the oceans.


Naval Observatory, Washington D.C.
In 1842, he became the superintendent of the Navy’s Depot of charts. There he had access to ships logs, charts and various instruments used in navigation. Later at his behest the Depot of Charts became the United States Naval Observatory. He used his knowledge of meteorology to assist in mapping the ocean currents.


In 1847 he published the Wind and Current Charts of the North Atlantic. Then in 1851 his book, Explanations and Sailing Directions to Accompany the Wind and Current Charts
came out. His most famous book, The Physical Geography of the Sea came out in 1855. These books were used to develop more charts to assist the sailors as they used the various trade routes.


Monument in Richmond, VA
Maury went on to write many more books. He became a professor of meteorology at the Virginia Military Institute. He did many lecture tours and received honors from all over the world. Maury Hall at the Naval Academy was named for him. Monuments were created to honor him. He is named “Pathfinder of the Seas” and the “Father of Modern Oceanography.”


Throughout all his work, and in his books, Maury always gave credit to the Bible and believed God had given us guidance through this great book. He gave credit to the Bible for the vision he had that was ahead of his time. He even mapped out places where cables could be strung across the ocean, an advanced idea for his time period.


Maury died in 1873 after he took ill during an intense lecture tour. His work continues on and has benefited all of us.



Have you ever heard of Matthew Maury? Have you seen charts of the ocean currents or heard them referenced during weather reports? This is a fascinating idea and I loved that his inspiration came from listening to the Bible being read aloud at a time when he was unable to get up.
