Whether you are a gemstone enthusiast, a jewelry buyer, or simply curious about the symbolism behind birthstones, this comprehensive overview will provide valuable insights into the gemstones that define May.
History and Lore of the May Birthstones
The Emerald: A Gemstone of Ancient Reverence
The emerald has a long and storied history that spans across cultures and continents. As early as 2,970 BCE, emeralds were being mined in Egypt, where they were used in jewelry and placed in tombs as symbols of eternal life and youth. Ancient Egyptians believed that emeralds represented the heart of the sun god Ra and associated the gem with fertility and rebirth. The Greek historian Pliny the Elder wrote about emeralds in his Naturalis Historia, noting their beauty and the laborious process of mining them in the mines of Egypt and later in South America.
During the Renaissance, emeralds gained popularity among European royalty. Spanish conquistadors brought vast quantities of emeralds from South America—particularly from Colombia—after the conquest of the New World. The gemstone became a symbol of luxury and power, adorning the crowns and jewelry of European nobility. In the 16th century, the emerald was believed to have protective qualities; it was thought to ward off enchantments and promote good health.
In modern times, the emerald is often associated with love and commitment. It is one of the four classical precious stones (alongside the diamond, ruby, and sapphire) and is frequently used in engagement rings and anniversary jewelry. The emerald's deep green color is also linked to the heart chakra in metaphysical traditions, symbolizing emotional balance and unconditional love.
Agate and Chrysoprase: Earthly Companions
While emerald is the most prominent May birthstone, agate and chrysoprase are also recognized as alternatives. Agate has been valued for its durability and aesthetic qualities since ancient times. It was used by the Egyptians for amulets and by the Greeks for protective talismans. Agate was particularly popular during the Victorian era, when it was incorporated into mourning jewelry due to its association with strength and resilience.
Chrysoprase, a type of green chalcedony, was discovered in Germany in the 16th century and later in Australia, where large deposits were found. Known for its bright apple-green color, chrysoprase was considered a gemstone of joy and optimism. It was also believed to have healing properties, particularly for the heart and circulatory system.
These alternative May birthstones reflect the diversity of green gemstones and their varied meanings. Agate and chrysoprase offer a more earthy and affordable option to the precious emerald, while still carrying symbolic significance.
Geological Formation and Sources of May Birthstones
The Emerald: A Beryl of Transformation
Emerald is a variety of the mineral beryl, with its green color derived from trace amounts of chromium or vanadium. Beryl forms in granitic pegmatites and metamorphic rocks under high-temperature conditions. The presence of these trace elements during the crystal's formation gives the emerald its signature green color. Emeralds are typically found in Colombia, where the majority of the world's emeralds are mined. The Muzo and Chivor mines in Colombia are particularly famous for producing high-quality emeralds with rich color and clarity.
Emeralds are known for their inclusions, which are natural imperfections that form during the crystal's growth. These inclusions, often referred to as "花园" (gardens), are considered part of the gemstone's character and can be used to determine its origin. Colombian emeralds, for example, are often identified by their hexagonal and two-phase inclusions.
Emerald has a hardness of 7.5–8 on the Mohs scale, which means it is relatively hard but also brittle. This combination of properties makes emeralds susceptible to cracking or chipping if subjected to impact or extreme heat. As a result, emeralds are typically set in protective settings, such as bezel settings, to minimize the risk of damage.
Agate and Chrysoprase: Earth-Friendly Gemstones
Agate is a type of chalcedony, a microcrystalline form of quartz. It forms in cavities within volcanic rocks and is often found in layers or bands of different colors. Agate is known for its durability and is widely distributed around the world. Major sources of agate include Brazil, India, and the United States. The gemstone is available in a wide range of colors and patterns, making it a popular choice for both jewelry and decorative objects.
Chrysoprase is a green variety of chalcedony that gets its color from trace amounts of nickel. It forms in the same geological environments as agate and is found in several locations around the world, including Australia, Germany, and the United States. Chrysoprase is known for its bright apple-green color and is often used in cabochons or beads. It has a hardness of 6.5–7 on the Mohs scale, making it more durable than emerald but less hard than quartz.
Both agate and chrysoprase are more affordable than emerald and are often used as alternatives in jewelry. Their earthy tones and natural patterns make them versatile choices for a wide range of styles, from minimalist designs to bold, statement pieces.
Gemological Properties of May Birthstones
Emerald: A Precious Green Gem
Emerald is a precious gemstone with unique physical and optical properties. It is a beryl, a mineral composed of beryllium aluminum silicate (Be₃Al₂(SiO₃)₆). The presence of chromium or vanadium in the crystal lattice gives emeralds their green color. Emeralds have a refractive index of 1.57–1.58 and a specific gravity of 2.72–2.78, making them relatively heavy for their size.
Emeralds are known for their inclusions, which are natural imperfections that form during the crystal's growth. These inclusions, often referred to as "gardens," are considered part of the gemstone's character and can be used to determine its origin. Colombian emeralds, for example, are often identified by their hexagonal and two-phase inclusions.

Care and Cleaning of May Birthstones
Emerald: A Delicate Treasure
Emeralds require special care due to their inclusions and relative brittleness. They should be cleaned with a mild soap solution and a soft cloth to avoid damaging the stone or its setting. Ultrasonic cleaners and steam cleaners should be used with caution, as they can cause damage to emeralds if not properly monitored.
Emeralds should be stored separately from other gemstones to prevent scratches or chips. They should also be kept away from extreme temperatures and direct sunlight, as heat can cause the gemstone to become brittle and increase the risk of cracking.
When wearing emerald jewelry, it is important to avoid activities that could subject the stone to impact or pressure. Emeralds should be removed before engaging in physical activities or using harsh chemicals, such as those found in household cleaners or chlorinated water.
Agate and Chrysoprase: Durable and Easy to Care For
Agate and chrysoprase are both durable gemstones that can be cleaned easily. They can be cleaned with a mild soap solution and a soft cloth or a soft-bristled brush. Ultrasonic cleaners and steam cleaners can also be used to clean these gemstones, as they are less sensitive to heat and pressure than emeralds.
Agate and chrysoprase should be stored in a dry, cool place to prevent damage from moisture or extreme temperatures. They should also be stored separately from other gemstones to prevent scratches or chips.
