The birthstone for July, Ruby is one of the so-called ‘big four’ gemstones (along with Diamond, Sapphire and Emerald) and is a member of the corundum family of gems. Considered by some to be the stone of love, it is also used to celebrate the 15th and the 40th wedding anniversaries. It’s a very hard stone that will keep its rich lustre for many years… if looked after carefully.
