History and Lore
The Legacy of Ruby
Ruby has a long and storied history that spans across cultures and centuries. In ancient India, Ruby was considered the "king of precious stones" due to its rarity, hardness, and beauty. It was believed to possess mystical powers that could protect the wearer from harm and bring about prosperity. The deep red color of the ruby was often associated with the life force of blood, making it a symbol of power and youthful energy.
In Burmese culture, rubies were believed to make warriors invincible in battle. This belief was so strong that many warriors wore rubies into battle to invoke their protective qualities. The ruby was also thought to have the power to predict misfortune or danger, making it a popular talisman for those who wished to avoid negative outcomes.
Throughout history, rubies have been cherished by royalty and nobility. Many royal crowns and jewelry pieces have been adorned with rubies, symbolizing power and divine favor. The ruby's association with the heart chakra is also significant, as it is believed to stimulate feelings of love and compassion. This makes the ruby not only a gemstone of beauty but also one of profound emotional significance.
The Mystique of Onyx
While Ruby is often the more prominent of the two July 4th birthstones, Onyx has its own rich history and cultural significance. Onyx is a type of chalcedony, a microcrystalline variety of quartz, known for its parallel bands of color. The most common form of onyx is black, but it can also be found in a variety of colors, including white, red, and even rainbow hues.
Historically, onyx has been used as a protective stone. Ancient Greeks and Romans believed that onyx could ward off negative energy and promote strength and vitality. It was often used in amulets and talismans to provide protection during travel or in battle. In medieval Europe, onyx was associated with the zodiac sign Taurus and was believed to bring stability and confidence to those born under this sign.
Onyx has also been used in various spiritual practices. It is often used in meditation to help ground the wearer and promote emotional stability. The stone's grounding energy is thought to help individuals stay centered and focused, making it an ideal companion for those seeking clarity and strength in their lives.
Geological Formation and Sources
Formation of Ruby
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The characteristic red color of ruby is due to the presence of trace amounts of chromium. The more chromium present, the stronger the red color. This is why the most valuable rubies are those with a deep red hue, often referred to as "pigeon's blood" red.
Ruby is formed under intense heat and pressure deep within the Earth's crust. It is typically found in metamorphic rocks such as marble and in igneous rocks such as basalt. The conditions required for the formation of ruby are quite specific, which is why ruby deposits are relatively rare.
Some of the most famous ruby sources include Burma (now Myanmar), which is known for producing high-quality "pigeon's blood" rubies. Other significant ruby-producing countries include Thailand, Sri Lanka, Afghanistan, and Madagascar. Each of these locations has its own unique geological conditions that contribute to the formation of rubies with distinct characteristics.
Formation of Onyx
Onyx, as a type of chalcedony, is formed from the deposition of silica in the form of microcrystalline quartz. It is typically found in sedimentary rocks, where it forms in layers over time. The parallel bands of color in onyx are a result of the alternating deposition of different minerals during the formation process.
Onyx is commonly found in various parts of the world, including Brazil, India, Mexico, and the United States. Brazil is one of the largest producers of onyx, particularly the black variety. The stone is often mined in large quantities and is used in a variety of applications, from jewelry to decorative objects.
The different colors of onyx are due to the presence of various impurities during the formation process. For example, red onyx is formed when iron is present, while black onyx is formed when carbon is present. These impurities not only affect the color of the stone but also its overall appearance and durability.
Gemological Properties
Ruby's Scientific Characteristics
Ruby is one of the most durable gemstones, with a hardness of 9 on the Mohs Hardness Scale. This makes it second only to diamond in terms of hardness, which means that it is highly resistant to scratches and abrasions. This durability makes ruby an excellent choice for everyday jewelry, as it can withstand the rigors of daily wear.
The refractive index of ruby ranges from 1.76 to 1.78, which gives it a brilliant luster that enhances its beauty. The specific gravity of ruby is around 4.00, which is relatively high compared to other gemstones. This high specific gravity is due to the dense structure of the corundum crystal lattice.
Ruby is also known for its pleochroism, which means that it can exhibit different colors when viewed from different angles. However, this property is not as pronounced in ruby as it is in some other gemstones. The most valuable rubies are those with a deep red color and a slight hint of blue, known as "pigeon's blood." This color is highly prized in the gem trade and can significantly affect the value of a ruby.
Onyx's Scientific Characteristics
Onyx, being a type of chalcedony, has a hardness of 6.5 to 7 on the Mohs Hardness Scale. While it is not as hard as ruby, it is still relatively durable and can be used in various types of jewelry. However, onyx is more susceptible to scratches and abrasions compared to ruby, so it requires more careful handling.
The refractive index of onyx ranges from 1.48 to 1.53, which gives it a moderate luster. The specific gravity of onyx is around 2.58 to 2.64, which is lower than that of ruby. This lower specific gravity is due to the less dense structure of the chalcedony crystal lattice.
Onyx is also known for its ability to take a high polish, which enhances its appearance and makes it a popular choice for cabochons and beads. The different colors of onyx can be used to create a variety of designs, making it a versatile gemstone for jewelry and decorative objects.

Care and Cleaning
Caring for Ruby
Due to its high hardness, ruby is relatively easy to care for. However, it is still important to take certain precautions to ensure that it remains in good condition. Ruby is sensitive to high heat and sudden temperature changes, so it is important to avoid exposing it to extreme temperatures. This is particularly important if you plan to clean your ruby with steam or ultrasonic cleaners, as these methods can cause damage.
When cleaning ruby, it is best to use a soft cloth and a mild soap solution. Avoid using harsh chemicals or abrasive materials, as these can scratch the surface of the stone. It is also important to avoid exposing ruby to chlorine, as this can cause damage to the gemstone.
When storing ruby jewelry, it is best to keep it in a soft pouch or a jewelry box to prevent scratches. It is also a good idea to store ruby separately from other gemstones, as harder gemstones can scratch softer ones. By following these simple care and cleaning tips, you can help ensure that your ruby remains beautiful and valuable for years to come.
