Coloured Gemstones: Rubies May 22, 2018 – Posted in: Our Blog

Aaron Signature School Series

We love rubies! They are pink to blood-red in colour. Blood-red or pigeon blood is the brightest and most valuable shade of red. The trace element that makes rubies red is chromium. The ruby is the traditional birthstone for July, and makes the perfect gift for 15th and 40th anniversaries!
