If the Northern Lights had a physical form, it would look something like this Labradorite Oval gemstone. The Labradorite Oval at 179.92ct is one of the most visually arresting loose gemstones in the UK market right now, and that is entirely down to its labradorescence, the optical phenomenon that sends flashes of iridescent colour dancing across the surface in ways that shift and surprise with every turn. The oval cut is a particularly good choice here. Its elongated, symmetrical form gives the stone more surface area, meaning more of that colour play is visible at once. Labradorite has long been likened to the Aurora Borealis and it earns that comparison completely. Display it on a mantlepiece and it becomes a talking point. Take it into a meditation practice and it brings the grounding, protective energy this stone is known for. As a loose gemstone gift for crystal enthusiasts, collectors or anyone drawn to natural wonders, it is genuinely hard to beat.

• Oval cut maximises the stone's iridescent colour display.
• Labradorescence mirrors the Aurora Borealis in real life.
• 179.92ct loose gemstone, highly collectible for UK mineral enthusiasts.
• Valued in crystal healing for protective and grounding properties.
