What Colour Is the July Birthstone?
Rubies are famous for their deep red to purplish-red shades. A rubies red colour comes from its composition of chromium with aluminium oxide. However a ruby will be affected by the trace amounts of chromium and iron in their environment during formation giving a wide range of variants from pinkish red, purplish red and brownish red, meaning every natural ruby will have a unique and distinctive colour.

Today, gifting a ruby conveys deep affection and a promise of enduring loyalty - perfect for marking July birthdays for a loved one or for a meaningful milestone with your partner such as your 40th wedding anniversary which is known as the ruby anniversary.
How Are Rubies Formed?
Rubies are a variety of the mineral corundum just like sapphire, formed deep within the Earth’s crust under extreme heat and pressure.

How to care for Ruby Jewellery
Keep your ruby jewellery in a soft pouch or jewellery box away from other jewellery pieces so that they do not touch or rub to avoid scratching. When it’s time for a clean, mix some warm soapy water, give the ruby a gentle brush with a soft toothbrush, rinse, and pat dry with a soft cloth. Avoid harsh cleaners or soaking for a long time, and always pop your ruby jewellery on last after you’ve sprayed perfume or smoothed on lotion. That way, it stays bright and sparkly for years to come and you do not get liquids and creams stuck in the setting.
