Cosmic microwave background necklace, showing the birth of the universe.

I designed this statement necklace shortly after finishing my PhD in Astrophysics! It combines my love of science and laser cut jewellery. I hope you love it as much as I do. As a scientist, I love accuracy. That's why I produced this necklace using the most up-to-date data from the Planck spacecraft.

Remember on old TVs when you'd get a fuzzy black and white screen when you lost signal? That's a signature of the radiation left over from the Big Bang! When the universe was just 380,000 years old (pretty young compared to today - it's now approximately 13.8 billion years old!), atoms and photons decoupled which effectively made the universe transparent. At that time, the average temperature of all the 'stuff' in space was around 3000K (~2700°C), but it's been cooling down ever since, so the temperature of space is now 2.7K (-270.45°C. Pretty chilly!). On this necklace the darker bits represent the coolest areas, and the lighter bits represent the warmer spots. The line across the centre shows the 'galactic extinction' at 353GHz - this is where the dust from our own galaxy, the Milky Way, is obscuring the CMB!

This necklace is the perfect gift for any astronomy fan or science geek! It comes beautifully gift-wrapped in a branded Becky, Queen of Frocks box. If you have any questions, just send me a message.

All my items are beautifully finished and are hand-made by me in my Paris studio.
