Included and flawed, but still a laurellite, cuprian, Mozambique#1164

Included Laurellite, reverse color changer, cuprian, Mozambique. This standard round brilliant still is flashy and reasonable clean face up, despite its flaws and lower quality crystal. It is a nice gemstone that is very rare. It comes from Mozambique and is cuprian. it weighs .90 carats.

The list of problems in the title makes this stone sound worse than it looks.  The flaws are not under the table and the inclusion/poor crystal is not bad enough to stop the standard round brilliant from flashing.  So this is a nice little Laurellite.  Laurellite is a name I gave to a new variety of Elbaite, tourmaline, that comes from Mozambique.  It is cuprian and has a reverse alexandrite color change change from purple/violet in daylight (cool) and blue/blue green in incandescent light (warm).  This reverse color change is unique in the world of gemstones.  I am personally surprised that I was able to get another piece of this very rare material since most of the purples from Mozambique, like the ones from Paraiba before them, are heated to product the cyan blue Paraiba or paraiba type gemstones.  This unexpected surprise weighs .90 carats.

About Bruce Fry

I was born in Summit, NJ in 1947 and graduated from Summit High School in 1966. I graduated from the Colorado School of Mines in 1970 and after spending another year in graduate school, I left to see the world of Brazil. After spending some more time discovering myself, I ended up working for the Commonwealth of Pennsylvania for 32 years as an Air Quality Engineer in the Department of Environmental Protection. I retired in 2007 and took up faceting gemstones again after a long hiatus that reached back to my twenties. I had started cutting cabochons when I was 13 and bought my first faceting machine when I was 15, but ran out of money and time until I retired.
My great love in gemology is tourmaline and the collection presented here represents my effort to get as much beauty and variety in the colors of tourmaline as I can. I was particularly lucky in being able to get unheated cuprian tourmaline before copper was discovered in gem grade tourmaline from Mozambique.
