Rubies are actually sapphires’ dramatic sibling.
Both are corundum — the only thing that makes a ruby a ruby is chromium, which gives it that fiery red.
I’m using a UV torch to invigorate the chromium - the red in garnet most often comes from iron which doesn’t react to this test
Rubies glow under UV light.
Thanks again to chromium, many rubies literally fluoresce. They can look like they’re glowing from within ✨
They’re seriously tough.
Rubies score 9 on the Mohs hardness scale, making them one of the hardest gemstones — perfect for everyday jewellery.
Rubies symbolise love, courage, and confidence.
They’ve long been associated with passion, vitality, and protection — basically the gemstone equivalent of walking tall.
Also, the perfect stone for valentine’s day! Just sayin’
