The ultra quirky, ultra colourful lamp you’ll love having in your favourite space. The Rainbow Diamond Motion Lamp is a gorgeously hypnotic lava lamp that features every colour of the rainbow on a gradient – deep red, bold orange, bright yellow, emerald green, sky blue and jewel purple.
The stand features a unique hourglass shape that blends into the elongated diamond shape of the lamp. The gradient glass lamp is full of fun lava that swirls, bubbles and ripples when the lamp is lit, putting on an endless show that’s most striking when the rest of the lights are low. Turn this lamp on when you want to relax, spend some time thinking, or just admire a beautiful colour show.

How does it work?
This lamp contains two liquids, each one close to the other in density but completely insoluble in each other. When the lamp is switched on the bulb produces a heat that is absorbed by the heavier liquid, causing it to expand and become less dense, ultimately rising in the lamp and creating the lava effect. When the lamp is switched off the liquid cools and slowly sinks to the bottom.
