Those HG Ripples are amazing.
Platinum was used during WWII for something related to defense, so yellow gold was popular for jewelry instead. The gas pipe necklaces were very modern looking (what we would call Retro now), and basically looked like pipes that were round on the upper side and flat on the backside. They were slightly stretchy.

So if your necklace was from the 1940s, you have a beautiful retro gas pipe necklace.
Today we had our Diwali celebration at work. It was a huge success. I got my sari on upside down and backwards this morning. Took it off, and then got it twisted in a moebius loop, don't ask me how. I got it on right the third try and it stayed on all day. It was really comfortable.
So, a bit of a repeat. The previous sari pics were practice. Today was the real deal. Here's a photo of me in the sari at work with my double strand of PP 8mm Freshadamas:
My aunt wearing the same sari in 1944. The black and white film back then was not sensitive to the color blue, which is why the sari looks white in this photo.
And they henna-ed my hand, too. Such fun. I'm not sure I got much actual work done today.
