The original James Webb Space Telescope necklace, as seen on NASA broadcasts

This is the second piece in my new collection which pays tribute to some of the coolest telescopes around (which all started with my old favourite, the Lovell Telescope). It shows the eighteen super shiny mirrors of JWST, and comes on a silver plated chain with a lobster clasp closure.

JWST launched 25th December 2021, which was the greatest Christmas present ever!

I make other versions of this design! Find them here:

Many moons ago, before I started my PhD in astronomy, I remember going to a talk about JWST at the Royal Observatory in Edinburgh. The speaker used an overhead projector to shine a hexagon on the wall which was 1.32 metres across - the same size as each of JWST’s mirrored panels. The mirrors on my necklace version are significantly smaller (to make them wearable!) - a scale of 1:2167, to be precise!

Each of these necklaces started its life on my computer. I digitally drew each of the 18 panels and other necklace components, then translated the designs into files that can be read by my laser cutter. This machine is the focus of my studio, and I’ve spent years hacking and tweaking it to perfection. I laser cut, assemble and polish the mirrored piece, before hanging it on a silver plated chain with a lobster clasp closure. I then carefully place it on a backing card in a Cepheid Studio branded gift box, ready for wrapping and sending to you, its new owner!

If you’re buying this necklace as a gift I can include your gift message in the parcel and send it straight to the recipient.

Although the item was lost in the mail, the supplier and Etsy were very helpful in providing me with customer support and a refund. I am grateful for that , even though I am disappointed to have not received it
