July & August Spotlight: High-End Jewelry With Ruby, Peridot, Sardonyx, Spinel

Let’s face it: it can be hard to decide on a birthday present for your loved one.

If your loved one is a summer baby, though, why not give the gift of high-end jewelry that shows off their birthstone? In today’s blog, we’re going to cover the July and August birthstones. So whether you’re shopping for a friend’s birthday or are treating yourself, here at Altier Jewelers we’re happy to let you in on some of the history and significance of these birthstones.

July: Ruby

The name ruby comes from rubeus, which is Latin for red. Ruby is the red variety of the mineral corundum, which becomes red because of the element chromium; other colors of corundum are known as sapphire. Chromium actually causes cracks and fissures in the gem, so few actually grow large enough to crystallize into fine-quality gems. It’s for this reason that larger ones are expensive and can even cost more than diamonds.

Rubies measure 9 on the Mohs scale, with diamonds as the only natural gemstone that’s harder. The Mogok Valley and the Mong Hsu region in Myanmar are both famous for ruby deposits, though they can also be found in Thailand, India, Vietnam, parts of the Middle East, the United States, and East Africa.

Ruby represents strong feelings of love, passion, energy, and power. It is believed to restore vitality and youth when it is rubbed on your skin and to promote courage, awareness, and success.


August: Peridot, Sardonyx, & Spinel


This gem is easily recognized for its lime-green glow, but the process by which it’s formed is rather unique. The mineral olivine forms inside the earth’s mantle and is then brought to the surface by volcanoes. The green color actually comes from the composition of the mineral rather than from trace impurities as happens with many other gems. This is why peridot only comes in one color (though shades will vary depending on the amount of iron present).

It’s rated as a 6.5 to 7 on the Mohs scale. Most of the gem is found in the San Carlos Reservation in Arizona, but it can also be found in Pakistan, Africa, Myanmar, and China.

Peridot represents strength and supposedly possesses healing properties that protect against evil and nightmares, and babies born in August are supposed to be guarded by its good fortune.


The name is derived from the gem’s alternating layers of sard and onyx, which together create a red and white striped stone. Sard and onyx are both types of the mineral chalcedony. The striped layers are parallel, however, unlike curved bands in other types of chalcedony.

This gem measures 6.5 on the Mohs hardness scale. It’s primarily found in India, but can also be found in Brazil, Madagascar, Germany, Uruguay, and even the United States.

This stone is used for strength and protection, and it represents courage, clear communication, and happiness. It is said to bring long-term happiness and stability to relationships. Some people believe that placing sardonyx in each corner of a house will protect against evil.


If you’ve never heard of spinel before, then that’s OK. Throughout much of history, and even today, it was frequently thought to be other gems (such as ruby or sapphire) because of their strong resemblance. Because of the close resemblance, many famous rubies in history were later discovered to actually be spinel. It’s often red, but can also be found in cobalt blue, pink, orange, mauve, yellow, and other colors.

Spinel ranks 8 on the Mohs scale. While extremely hard and durable, this is one of the features that distinguishes it from the harder rubies and sapphires. Spinel has been found in large quantities in Cambodia, Sri Lanka, Myanmar, and Thailand, but it has also been found in Australia, Madagascar, Tanzania, Brazil, and other countries.

This gem is known for its revitalizing properties. If you’re a workaholic, are stressed, or are full of anxiety, this can help replenish your low energy levels, release tension and anxiety, and inspire you.
