CAFFEINE EARRINGS - CAFFEINE CRYSTALS BY POLARISED LIGHT MICROSCOPY (ER34)

These caffeine crystal earrings would make a great gift for a coffee lover!

A solution of pure caffeine was evaporated on a microscope slide to form crystals. By viewing these crystals using polarised light microscopy, amazing and interesting colours and patterns are seen. This is due to the crystals forming regular arrays and interfering with the light path to give the colours seen (no colours were changed using Photoshop).

Interesting and unusual science earrings ideal for anyone interested in science and the natural world. 

Earrings are printed onto one side of 0.5mm thick Aluminium (reverse side plain Aluminium finish) to give a lightweight and durable glossy and scratch resistant earring. 
Aluminium discs measure 16mm in diameter and are mounted on either silver plated or hypoallergenic surgical steel earring wires (please choose from the drop down menu). Please note that due to the nature of the metal the surgical steel hooks are slightly less bright and shiny than the silver plated ones shown in the image. They still look great though! 
Total length from top of earwire to bottom of disc 32mm.

Supplied in a gift box complete with a description of the image.
