To wrap up Earth Science Week it seemed appropriate to mention the pioneering geologist and professor, Florence Bascom.
When she got her doctorate in geology in 1893, Bascom was the first woman to obtain a doctorate from Johns Hopkins.
She was the second woman to have a PhD in geology in the United States. (The first was Mary Emilee Holmes, University of Michigan, 1888.*) She is also credited with being the first woman to be hired by the United States Geological Service, the first woman to present a scientific paper at the Geological Society of Washington, and the first female officer of the Geological Society of America.

Since today is National Fossil DayTM, I wanted to do a bit of a show-and-tell. I love working with fossils in my jewelry, and a number of them have ended up on here, so I thought I’d do a brief overview of the ones I use most often
Fossils are fascinating. Just think for a minute about the intricacy of ancient life that they preserve. They’re like little time capsules.
Okay, so I didn’t know this was a thing, but I found out there is a National Fossil DayTM here in the States. It’s the Wednesday of Earth Science Week in October.
Now that is my kind of holiday. The idea behind it is to show how much we can learn about the past (and possibly predict about the future) from fossils and the need to understand and preserve them.
The National Park Service has some great art and articles as well as a list of related events-check to see if there’s anything going on in your area!
Sir John’s Hatter
Today is Mad Hatter Day. (At least in the US. I guess it’d be June 10th in Europe.) Mad Hatter Day was inspired by Lewis Carroll’s Alice in Wonderland.
When I was younger I was always annoyed that everything October was pink. October’s birthstones are opal and tourmaline. Opal being a pricey stone and not super cheap even in lab grown options, pink rhinestones were the way to go in key chains, toy rings, and other such birthday/astrologically themed trinkets.
A piece of lapis with a wire work bail I made to echo its pyrite sparkles.
Lapis is sometimes considered a secondary birthstone to sapphire. That’s probably due to its brilliant blue color, and the fact that through the middle ages the word sapphire was used pretty loosely!
Lapis is a vibrant blue stone consisting of lazurite and usually pyrite and sodalite as well as a host of other minerals. It’s the pyrite that gives lapis its midnight sparkle of stars.
The green gemstone peridot is the most popular birthstone for August, but it has another, less gemmy birthstone, sardonyx. It seems fitting that one of August’s stones is all sparkle and leaf green, while the other is duller and browner and edging into fall.
Sardonyx is a type of onyx that can be found in shades of browns and reds as mixed with black or white. It’s more common than black onyx (which is naturally bands of black and white-not solid), but since black onyx is a higher demand stone, sardonyx is often dyed black. The sard prefix probably comes from a Persian root for yellowish red. Its colors form very even and straight bands.
