History and Lore of Birthstones
The tradition of associating specific gemstones with birth months is deeply rooted in antiquity, with its most famous precursor being the biblical Breastplate of Aaron. As described in the Book of Exodus, this sacred vestment was adorned with twelve distinct stones, each representing one of the twelve tribes of Israel. This early association of stones with specific groups laid the groundwork for the later tradition of linking gems to individuals. Over the ensuing centuries, the practice evolved, with various cultures attributing different meanings and powers to the stones associated with each month. The specific list of birthstones has shifted over time, influenced by trade, availability, and cultural preferences.
By the 19th century, the custom of wearing a gemstone corresponding to one's birth month had gained considerable popularity in Europe. This trend eventually crossed the Atlantic and took root in the United States, where it was further formalized. The modern list of birthstones, as recognized by many in the jewelry industry today, was largely standardized in the early 20th century, though variations still exist. For instance, some months are associated with multiple stones, offering a range of options in color and price. This historical journey from the Breastplate of Aaron to contemporary jewelry counters illustrates the enduring human fascination with these natural treasures.
Kendra Scott’s BFF collection draws directly from this rich history, selecting birthstones that carry their own unique stories and symbolism. For example, the gemstone for January, garnet, is historically associated with protection and friendship. Its deep red hue has long been a symbol of vitality and enduring bonds, making it a fitting choice for a collection centered on friendship. Similarly, February’s amethyst is believed in various traditions to bring courage and clarity of mind. The ancient Greeks and Romans associated amethyst with Bacchus, the god of wine, believing it could prevent intoxication and maintain a clear head. These historical attributions add a layer of depth to the gems, allowing each piece in the BFF collection to serve as a tangible representation of the qualities that define a relationship.
The BFF collection is particularly significant in that it allows individuals to express friendship through the gift of jewelry. Whether given to mark a birthday, a graduation, or simply as a gesture to celebrate a lasting bond, these pieces are designed to be worn as a constant reminder of a shared connection. This modern application of an ancient tradition highlights how birthstone jewelry has evolved from a personal talisman to a medium for expressing interpersonal relationships. The collection’s success lies in its ability to weave together historical significance and contemporary sentiment, creating pieces that are both timeless and timely.
Geological Formation and Sources
The beauty and value of a birthstone are intrinsically linked to its geological origins. Each gemstone forms under specific conditions of heat, pressure, and chemical composition, resulting in a unique mineral structure. Understanding how these stones are formed provides insight into their properties and rarity. For instance, garnet, January’s birthstone, is not a single mineral but a group of silicate minerals that form in metamorphic and igneous rocks. The deep red variety, almandine, is commonly found in schist and gneiss, and major sources include India, Sri Lanka, and the United States.
Amethyst, February’s birthstone, is a variety of quartz, colored by iron impurities and natural irradiation. It forms in geodes and cavities within volcanic rocks, with significant deposits found in Brazil, Uruguay, and Zambia. The finest amethyst exhibits a deep, saturated purple with flashes of red, though lighter hues are also common. The formation process can take millions of years, making each stone a product of immense geological time.
Aquamarine, March’s birthstone, is a beryl variety colored by trace amounts of iron. It typically forms in pegmatites—coarse-grained igneous rocks—and is often found in large, well-formed crystals. Brazil, Nigeria, Madagascar, and Pakistan are key sources for high-quality aquamarine. The stone’s name, derived from the Latin for "seawater," reflects its captivating blue to blue-green hues, reminiscent of the ocean.
Diamond, April’s birthstone, is composed of pure carbon and forms under extreme pressure and temperature deep within the Earth’s mantle. It is brought to the surface through volcanic activity in kimberlite pipes. Major diamond sources include Botswana, Russia, Canada, and South Africa. While diamonds are renowned for their hardness and brilliance, their formation process is a testament to the powerful forces at work within the planet.
Emerald, May’s birthstone, is another beryl variety, colored by chromium and sometimes vanadium. It forms in hydrothermal veins and metamorphic rocks, often with inclusions that are considered part of its character. Colombia is the most famous source of high-quality emerald, with significant deposits also found in Zambia, Brazil, and Afghanistan.
Pearl, June’s birthstone, is unique among gemstones as it is organic, formed within the soft tissue of a living mollusk. Natural pearls are rare and form when an irritant, such as a grain of sand, is encased in layers of nacre. Cultured pearls, which make up the vast majority of the market today, are formed with human intervention. Major pearl-producing regions include Japan, China, and Australia.
Ruby, July’s birthstone, is a variety of corundum (aluminum oxide) colored by chromium. It forms in metamorphic rocks and is prized for its vibrant red hue. The finest rubies come from Myanmar (Burma), with other sources including Thailand, Sri Lanka, and Mozambique.
Peridot, August’s birthstone, is the gem-quality variety of olivine, a mineral that forms deep within the Earth’s mantle and is brought to the surface by volcanic activity. It is found in areas with recent volcanic activity, such as Arizona (USA), Pakistan, and Myanmar.
Sapphire, September’s birthstone, is also a variety of corundum, colored by trace elements like iron and titanium. While most famously blue, sapphires can occur in a range of colors (except red, which is ruby). Major sources include Sri Lanka, Madagascar, and Australia.
Opal, October’s birthstone, is a hydrated amorphous silica, formed in areas where silica-rich water seeps into cracks and voids in rocks. Australia is the primary source of precious opal, known for its play-of-color, a phenomenon caused by the diffraction of light through its internal structure.
Topaz, November’s birthstone, is a silicate mineral that forms in igneous rocks like granite and rhyolite. It can be found in many colors, but the most prized is the imperial topaz, a rich orange-pink. Sources include Brazil, Nigeria, and Sri Lanka.
Turquoise, December’s birthstone, is an opaque, blue-to-green mineral composed of copper and aluminum phosphate. It forms in arid regions where acidic water percolates through rocks containing these elements. Major sources include the United States (Southwest), Iran, and China.
Kendra Scott’s commitment to ethical sourcing ensures that these gemstones are responsibly mined and processed, aligning with the values of an increasingly conscious consumer base. The brand’s focus on "vibrant, high-quality gemstones" means selecting stones for their rich, true-to-color hues, from January’s deep garnet to July’s fiery ruby and December’s cool blue topaz. Each gemstone is cut to enhance its natural sparkle, whether in a faceted oval, a smooth cabochon, or a tiny round stone, showcasing the inherent beauty derived from its geological journey.
Gemological Properties
The suitability of a gemstone for jewelry, particularly for rings that endure daily wear, is largely determined by its gemological properties. These properties include hardness, cleavage, toughness, and chemical stability. The Mohs scale of hardness, which ranks minerals from 1 (talc) to 10 (diamond), is a crucial reference. A gemstone used in a ring should ideally have a hardness of at least 7 to resist scratching from everyday materials like dust (quartz, hardness 7).
Below is a table summarizing key gemological properties of the birthstones mentioned, based on standard gemological data. This information is essential for understanding why certain stones are better suited for specific types of jewelry and how they should be cared for.

When selecting a birthstone for a ring, especially one designed for daily wear like those in Kendra Scott’s collection, durability is paramount. Stones like diamond, sapphire, and ruby (hardness 9-10) are ideal. Aquamarine, emerald, and topaz (hardness 7.5-8) are also excellent choices. Amethyst, garnet, and peridot (hardness 6.5-7) are suitable but may show wear over time if exposed to rough conditions. Softer stones like opal, turquoise, and especially pearl (hardness below 7) require more protective settings and careful handling, making them less common for rings meant for constant wear.
Kendra Scott’s designs take these properties into account. For instance, the Elisa ring features a bezel setting, which encircles the gemstone with metal, offering superior protection compared to prong settings, especially for stones with good cleavage or lower hardness. The low-profile design of the Elisa and Everly rings further minimizes the risk of snagging or impact damage. The brand’s use of a single, oval-cut or round-cut stone in these settings ensures the gem is secure while maximizing its visual impact.
Symbolism and Metaphysical Beliefs
Beyond their physical properties, birthstones are steeped in symbolism and metaphysical beliefs, which have been passed down through generations. These associations add a profound layer of meaning to the gems, making them more than just decorative objects. For many, wearing a birthstone is an act of connecting with these ancient beliefs and harnessing the stone’s purported energies.
Garnet (January) is widely believed to symbolize protection, especially during travel, and to foster friendship and trust. Its deep red color is associated with the life force, vitality, and passion. In medieval times, it was thought to ward off nightmares and protect against poison.
Amethyst (February) has long been associated with clarity of mind, calmness, and spiritual wisdom. The ancient Greeks believed it could prevent intoxication, while later Christian traditions linked it to piety and humility. It is often considered a stone of peace and emotional balance.

Kendra Scott’s BFF collection leverages these symbolic meanings to deepen the significance of the jewelry. For example, gifting a garnet ring to a friend symbolizes protection and enduring friendship, while an amethyst piece can represent clarity and courage in a relationship. The brand’s focus on personalization, such as adding a second birthstone for a child or partner, or engraving a date or initial, further enhances this symbolic layer, turning each piece into a unique narrative of connection and intention.
Care and Cleaning of Birthstone Jewelry
Proper care and cleaning are essential to preserve the beauty and longevity of birthstone jewelry. The specific maintenance required varies significantly based on the gemstone’s hardness, cleavage, and porosity. As a general rule, jewelry should be stored separately to avoid scratches, removed during activities that could cause impact or exposure to chemicals, and cleaned regularly using appropriate methods.
For harder stones like diamond, sapphire, and ruby (Mohs hardness 9-10), cleaning is straightforward. They can be safely cleaned with a soft brush, warm water, and a mild dish soap. Ultrasonic cleaners are generally safe for these stones, but caution is advised if the jewelry has been repaired or if the stone has inclusions that could be affected by vibrations.
Stones with good durability but specific sensitivities, such as aquamarine, emerald, and topaz (hardness 7.5-8), should be cleaned with the same mild soap and water solution. Avoid sudden temperature changes, as they can cause fractures in some stones. Ultrasonic cleaners are typically safe for aquamarine and topaz but should be avoided for emeralds, which often have inclusions (jardin) that could be dislodged by vibrations.
Softer stones like amethyst, garnet, and peridot (hardness 6.5-7) require more gentle care. Clean them with a soft cloth and mild soap, avoiding harsh chemicals or abrasives. Amethyst is particularly sensitive to prolonged exposure to strong sunlight or heat, which can cause its color to fade. Therefore, it should be stored away from direct light when not in use.
Opal, turquoise, and pearl (hardness below 7) demand the most careful handling. These stones are soft and porous. Clean them only with a soft, damp cloth—never use chemicals, soaps, or ultrasonic cleaners. Opals are sensitive to dehydration; store them in a soft cloth with a bit of moisture (e.g., a damp cotton ball in the jewelry box) to prevent cracking. Turquoise is often stabilized with resins or waxes to improve durability, but it should still be protected from chemicals, perfumes, and excessive moisture. Pearls are extremely delicate; wipe them with a soft cloth after each wear to remove body oils and store them separately to avoid scratches.
Kendra Scott’s birthstone rings are designed with wearability in mind. The low-profile settings and durable metal bands (14k gold-plated brass, silver-tone, or rose gold-plated brass) provide a good foundation, but the care of the gemstone itself must be tailored to its specific properties. For example, an Elisa ring with a garnet should be cleaned gently and stored carefully, while a ring with a diamond or sapphire can withstand more robust cleaning methods. The brand’s emphasis on ethical sourcing and quality craftsmanship ensures that the jewelry is built to last, but owner diligence in care is crucial for maintaining its sparkle and significance over time.
