You think sapphire = blue? Think again. 💙
Welcome to Sapphire School — Episode 1.
Sapphire is actually a variety of corundum — a remarkable mineral that appears in an extraordinary spectrum of colours.
Blue, pink, yellow, green, purple, parti-colour… and then there’s red corundum, which gets a name entirely of its own: ruby.
So sapphire isn’t simply a blue gemstone. It’s an entire world of colour.
This September, Jennifer is taking us inside the world of sapphire — from colour and origin to treatments, inclusions, history and what to look for when choosing a stone.
Which sapphire colour would you choose?
