These stones have captivated people for centuries with their rich histories, vibrant colors, and unique gemological properties. Whether you are a gemstone enthusiast, a jewelry buyer, or a student of gemology, this exploration will provide a comprehensive understanding of the significance and characteristics of these two birthstones.
History and Lore
Ruby: The July Birthstone
Ruby, the birthstone for July, has a storied history that spans continents and centuries. Known as the "king of precious stones" in ancient India, ruby was revered for its rarity, hardness, and beauty. The name "ruby" is derived from the Latin word ruber, meaning "red," a color traditionally associated with love and passion. The deep red hue of the finest rubies is often described as "pigeon's blood," a term that highlights the gemstone’s intense coloration due to trace amounts of chromium.
In medieval Europe, ruby was believed to bestow health, wisdom, wealth, and success in love. Burmese warriors carried rubies into battle, believing the gemstone granted them invincibility. These cultural associations have contributed to the ruby's enduring appeal and mystique. Ruby is also traditionally given as a gift for the 15th and 40th wedding anniversaries, further embedding it in the cultural fabric of relationships and milestones.
Topaz and Citrine: The November Birthstones
November is associated with two gemstones: topaz and citrine. While topaz is the traditional birthstone, citrine has also gained popularity as a modern alternative. Topaz has been known and used since ancient times. The name "topaz" is thought to derive from the Sanskrit word tapas, meaning "fire," a reference to the gemstone’s fiery colors and brilliance.
Citrine, on the other hand, is a variety of quartz known for its yellow to orange hues. The name "citrine" comes from the French word for lemon, reflecting its vibrant color. Citrine has been used in jewelry for centuries and is often associated with positive energy and cheerfulness. The modern birthstone chart includes both topaz and citrine for November, allowing for a broader range of choices for jewelry designers and consumers.
These gemstones carry with them a legacy of cultural significance and symbolic meaning. From ancient beliefs about their protective and healing properties to their role in contemporary jewelry, topaz and citrine continue to be valued for their beauty and the positive attributes they are believed to bring.
Geological Formation and Sources
Ruby Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃) with trace amounts of chromium that give it its characteristic red color. The presence of chromium determines the intensity of the red hue; the more chromium, the stronger the red color. The finest rubies are typically found in Myanmar (formerly Burma), which is renowned for producing "pigeon's blood" rubies. Other notable sources of ruby include Thailand, Sri Lanka, India, and Vietnam.
Ruby is formed under high-pressure and high-temperature conditions deep within the Earth's crust. The gemstone is typically found in metamorphic rocks, particularly in mica schists and gneisses. The formation process involves the slow crystallization of corundum over millions of years, during which trace elements like chromium are incorporated into the crystal lattice.
The hardness of ruby is second only to diamond, with a rating of 9 on the Mohs scale. This makes ruby a durable gemstone suitable for everyday wear. However, rubies can be sensitive to high heat and sudden temperature changes, which can cause them to fracture or lose their color.
Topaz and Citrine Formation and Sources
Topaz is a silicate mineral with the chemical formula Al₂SiO₄(F,OH)₂. It is known for its excellent clarity and hardness, which is 8 on the Mohs scale. Topaz is typically colorless in its pure form, but it can occur in a range of colors due to impurities and structural defects. The most common colors include yellow, orange, brown, and blue, with the golden topaz being particularly popular as a November birthstone.
Citrine is a variety of quartz that contains trace amounts of iron, which imparts its yellow to orange coloration. Unlike synthetic citrine, which is created through heat treatment of amethyst, natural citrine is relatively rare. It is primarily found in Brazil, which is the world's largest producer of citrine. Other sources include Madagascar, Spain, and the United States.
Both topaz and citrine are formed in different geological environments. Topaz is typically found in pegmatites, which are igneous rocks that form from the slow cooling of magma. Citrine, being a type of quartz, is often found in hydrothermal veins and sedimentary rocks. The formation of these gemstones requires specific conditions of temperature, pressure, and chemical composition.
In terms of hardness, topaz is slightly less hard than ruby but still durable enough for everyday use. Citrine, with a hardness of 7 on the Mohs scale, is also suitable for jewelry. However, both gemstones can be vulnerable to chipping or cracking if exposed to hard impacts or improper handling.
Gemological Properties
Ruby: A Masterpiece of Color and Hardness
Ruby is one of the most sought-after gemstones due to its exceptional hardness and vivid color. As a variety of corundum, ruby has a hardness of 9 on the Mohs scale, making it highly resistant to scratches. This property makes it ideal for use in jewelry that is worn regularly, such as rings and bracelets.
The refractive index of ruby ranges from 1.76 to 1.78, which contributes to its brilliance and sparkle. The gemstone's color is primarily due to the presence of chromium, which absorbs certain wavelengths of light and reflects the red color that is so characteristic of ruby. The most prized rubies exhibit a deep red with a slight purplish hue, known as "pigeon's blood."
Ruby is also known for its pleochroism, which is the ability to display different colors when viewed from different angles. In some cases, rubies can appear slightly pinkish or purplish depending on the angle of light. This optical phenomenon adds to the gemstone's allure and complexity.
In terms of clarity, rubies can vary from very clean to inclusion-heavy. The presence of inclusions can affect the gemstone's value, but some inclusions are actually desirable as they indicate the stone's natural origin. For example, silk-like inclusions composed of rutile needles can enhance the gemstone's appearance by creating a star effect when the ruby is cut as a cabochon.
Topaz and Citrine: Vibrant and Versatile
Topaz is a versatile gemstone that is available in a range of colors, with the golden topaz being particularly popular as a November birthstone. The gemstone has a hardness of 8 on the Mohs scale, which makes it durable and suitable for use in various types of jewelry. Topaz is also known for its excellent clarity, with many high-quality specimens being nearly flawless.
The refractive index of topaz ranges from 1.61 to 1.64, which contributes to its brilliance and fire. The gemstone's color can be affected by exposure to radiation, which can change its hue. For example, blue topaz is often created through irradiation of colorless topaz.
Citrine, as a variety of quartz, has a hardness of 7 on the Mohs scale. It is known for its warm yellow to orange colors, which are caused by trace amounts of iron in the crystal structure. Citrine is often heat-treated to enhance its color, and natural citrine is relatively rare compared to its heat-treated counterparts.
Both topaz and citrine are relatively stable and can be cleaned with mild soap and warm water. However, they should be handled with care to avoid exposure to harsh chemicals or extreme temperatures, which can affect their appearance and durability.
