The tradition of associating gemstones with specific months, and thus with the individuals born within them, is a practice steeped in history and lore. While the modern list of birthstones is relatively recent, formalized in 1912 by the National Association of Jewelers, the roots of this practice extend back to ancient civilizations. These stones were believed to possess unique powers, offering protection, health, and good fortune to those born under their influence. This article will explore the birthstones assigned to each month, drawing upon historical context and available gemological information.
Historical Origins and Evolution
The concept of linking gemstones to the calendar originated in ancient times, with connections made to astrological signs and the days of the week. Calendar days were named after celestial bodies, and corresponding stones were thought to absorb planetary energies, transferring them to the wearer. For example, gold topaz was associated with Sunday, representing the Sun’s energy, while a ruby or garnet was worn on Tuesday for Mars’ creativity and passion.
Over time, different cultures developed their own lists of birthstones. The ancient Hebrews associated specific stones with the twelve tribes of Israel, as represented on the Breastplate of Aaron. These associations gradually evolved, leading to variations in the stones assigned to each month. The modern birthstone list represents a consolidation of these traditions, with updates occurring as recently as 2016, when spinel was added as a birthstone for August by the American Gem Trade Association and the National Association of Jewelers. Currently, three sets of birthstones are recognized: ancient, traditional, and modern, offering a range of choices for each month.
Monthly Birthstones: A Comprehensive Overview
The following outlines the birthstones associated with each month, based on the modern list, alongside traditional alternatives where noted.
January: Garnet is the primary birthstone for January. It is a silicate mineral group encompassing a wide range of colors, including red, green, orange, purple, yellow, pink, and even black. While red is the most commonly recognized color, the variety is extensive. Garnets generally have a Mohs hardness of around 7, making them reasonably durable.
February: Amethyst is the birthstone for February. This variety of quartz is known for its purple hue.
March: Aquamarine is the modern birthstone for March, while bloodstone serves as the traditional alternative. Bloodstone is an opaque green variety of cryptocrystalline quartz with red spots caused by iron oxides. It has a hardness of 6.5 to 7.
April: Diamond is the birthstone for April, and remains consistent across both modern and traditional lists. Diamonds are renowned for their hardness, registering a 10 on the Mohs scale, and are cherished for their brilliance and value.
May: Emerald is the birthstone for May, also consistent across modern and traditional designations.
June: Alexandrite is the modern birthstone for June, with pearl as the traditional choice.
July: Ruby is the birthstone for July, maintaining its position in both modern and traditional lists.
August: Peridot and spinel are the birthstones for August. Historically, sardonyx was also associated with this month. Spinel comes in a variety of colors, including purple, orange, blue, green, pink, and red, and has a hardness of 8, making it suitable for everyday wear.
September: Sapphire is the birthstone for September, consistent across both modern and traditional lists.
October: Tourmaline is the modern birthstone for October, while opal is the traditional choice.
November: Citrine and golden topaz are the birthstones for November. Topaz was traditionally associated with this month.
December: Blue zircon and tanzanite are the modern birthstones for December, with turquoise and lapis lazuli serving as traditional alternatives.
Gemological Properties and Sources
The gemological properties of these birthstones vary significantly. Diamond, with a Mohs hardness of 10, is the hardest naturally occurring substance, while peridot, with a hardness of 6.5 to 7, is relatively soft. Garnet, as a group, exhibits a hardness around 7.
The sources of these gemstones are equally diverse. Garnets are found globally, with recent discoveries in Africa yielding spectacular colors. Rubies are sourced from Vietnam, Mozambique, Pakistan, Sri Lanka, and Madagascar. Spinel originates from Vietnam, Sri Lanka, Pakistan, Myanmar, Tajikistan, and Tanzania. Aquamarine and other gemstones are also sourced from various locations across Asia and Africa.
Symbolism and Metaphysical Beliefs
Throughout history, birthstones have been attributed with various symbolic meanings and metaphysical properties. Diamonds were believed to provide beauty, happiness, strength, and longevity. Bloodstone was thought to have healing properties, promoting health and youth, and even granting invisibility. Spinel was believed to promote harmony and cure inflammatory diseases. While these beliefs are not scientifically validated, they contribute to the enduring appeal and cultural significance of birthstones.
Care and Cleaning
The appropriate care for a birthstone depends on its hardness and composition. Diamonds, due to their exceptional hardness, are relatively durable and can withstand daily wear. However, softer stones like peridot require more careful handling to avoid scratches. Bloodstone should be protected from high temperatures and stored in soft fabric. Garnets, with a hardness of around 7, are reasonably tough but should still be protected from abrasive materials.
Days of the Week and Gemstones
Beyond monthly associations, gemstones were also linked to the days of the week, reflecting the influence of planetary energies. Gold topaz was worn on Sundays, moonstone or pearl on Mondays, ruby or garnet on Tuesdays, turquoise, sapphire, or lapis lazuli on Wednesdays, amethyst on Thursdays, emerald on Fridays, and diamond on Saturdays.
