July Birthstone Ruby

The birthstone for July is ruby. Ruby is not only a beautiful colour, for who doesn’t like ruby red lipstick or nail polish, it’s also a stunning gemstone.

How are Rubies Formed?

A ruby is the most valuable variety of corundum. Corundum is an extremely hard crystalized alumina. When some of the aluminium ions have been replaced by chromium and small impurities occur, a ruby is formed.
Chromium causes cracks and fissures which makes it difficult for rubies to grow large enough to make quality gems. Rubies are therefore rare and often more expensive than diamonds.
Only a red formation becomes a ruby, a white formation is known as a sapphire.

Sapphire is also a variety of corundum.
Ruby gets its vibrant red colour from fluorescence caused by the element chromium.

Where are Rubies Found?

For centuries the Mogok Valley in Myanmar was the world’s main source for mining rubies.  Rubies are now found and mined in Thailand, Cambodia, Afghanistan, Australia, Brazil, Columbia, India, Nambia, Japan, Madagascar, Pakistan, Tajikistan, Tanzania, and Vietnam. Sri Lanka has lighter red-coloured rubies known as pink sapphires.

Are Rubies Heat-Treated?

Yes, most rubies commercially offered have had some kind of treatment. An untreated ruby is rare and the most valuable of rubies.

For centuries rubies have usually been heat-treated to improve the colour and clarity of the gemstone. 

Often during heat-treatment, rubies are coated with fillers to fill cracks and prevent the gemstones from sticking together during heat-treatment.

What Colour is a Ruby?

Burmese rubies, also known as Pigeon Blood Rubies are found in Myanmar’s Mogok Valley and are the finest Rubies to be found, deep blood red with purple hues and are superior to the brown-orange gemstones found in Vietnam, Thailand India, the Middle East, Africa, and the United States.

July’s birthstone ruby is a vibrant red and the more orange or purple hue contained in a ruby decreases the value of the gemstone.

If a ruby doesn’t fall into the correct red it is considered to be a sapphire with a “fancy colour”.  The colours are orange, yellow, brown, green, blue, purple, violet, black and colourless.

Do Rubies Scratch Easily?

Rubies score 9 on the Mohs Hardness Scale, only a diamond is harder. Ruby does not scratch easily, however, always take good care of your jewellery and avoid hard knocks and contact with strong chemicals.

How do I Clean my Ruby Jewellery?

Clean your ruby birthstone jewellery with mild soapy lukewarm water, if needed, use a soft toothbrush. Rinse well and dry with a soft lint-free cloth.

How much is a Ruby worth per Carat?

Rubies are rarer than diamonds, therefore, large rubies can be worth more than a diamond of the same size. 

As with most gemstones, colours, clarity, and size dictate the value.

The strength and the red fluorescence make the ruby valuable in the production of medical instruments, laser industry, watchmaking and of course making of jewellery.

Can a Ruby be used in an Engagement Ring?

Yes! a July birthstone ruby engagement ring is beautiful whichever style you choose.

The colour red symbolizes love, hearts, roses and Valentine’s Day making ruby a perfect way to show love.
