Birthstones have captivated humanity for millennia, imbued with symbolism, lore, and aesthetic beauty. The practice of associating specific gemstones with months of the year, or even days of the week, dates back to ancient civilizations, with roots in biblical texts and astrological beliefs. While modern lists are standardized, the tradition allows for a remarkable range of personalization and meaning in jewelry. This article explores the diverse colors and origins of the twelve recognized birthstones, drawing upon historical context and gemological characteristics.
History and Lore
The origins of birthstones are deeply intertwined with historical and religious texts. References to twelve stones are found in the Book of Exodus, believed to represent the tribes of Israel, and were later associated with the months of the year. These early associations were not always consistent, and variations existed across different cultures. The standardization of birthstone lists largely occurred in the 19th and 20th centuries, particularly with the efforts of jewelry trade associations seeking to promote gem sales.
Throughout history, gemstones were believed to possess healing properties and offer protection to the wearer. These beliefs, stemming from ancient astrology and folklore, continue to influence the metaphysical associations of birthstones today. The practice of wearing gemstones corresponding to one’s birth month was thought to amplify their positive energies and provide specific benefits. The selection of stones for specific months was also influenced by their availability and perceived aesthetic qualities.

However, garnets are surprisingly diverse, ranging in color from reddish-orange to purple-red, and even appearing in rare yellow-gold and green shades.

It was promoted by Tiffany & Co. due to its international appeal.
Zodiac and Day of the Week Gemstones
Beyond monthly birthstones, gemstones have also been linked to zodiac signs and days of the week. Ancient astrologers assigned gemstones to planets, believing them to reflect celestial energies. These stones were thought to connect individuals to the heavens and offer specific benefits. For example, wearing a gold topaz on Sunday was believed to harness the Sun’s vibrant energy, while an emerald on Friday was associated with Venus’ love and excitement.
The following table summarizes the gemstones associated with each day of the week:
| Day of the Week | Stone | Color |
|---|---|---|
| Sunday | Gold Topaz | Gold |
| Monday | Moonstone/Pearl | Tranquil |
| Tuesday | Ruby/Garnet | Red |
| Wednesday | Turquoise/Sapphire/Lapis Lazuli | Blue/Green |
| Thursday | Amethyst | Purple |
| Friday | Emerald | Green |
| Saturday | Diamond | Clear |
Gemological Properties and Care
The hardness of gemstones, measured on the Mohs scale, influences their suitability for different types of jewelry. Zircon, for example, has a hardness of 6 to 7.5 and can be used in everyday jewelry with proper care. Tanzanite, also with a hardness of 6 to 7, is best suited for earrings or pendants due to its relative fragility. Diamonds, with a Mohs hardness of 10, are the hardest known natural substance and are exceptionally durable.
Many gemstones undergo treatments to enhance their color or clarity. Heat treatment is commonly used to produce different varieties of zircon. Proper care and cleaning are essential to maintain the beauty of any gemstone. Gentle cleaning with mild soap and warm water is generally recommended, avoiding harsh chemicals or abrasive materials.

From the deep reds of garnet to the vibrant blues of aquamarine and turquoise, each gemstone possesses a unique character and significance. Whether chosen for their aesthetic appeal, astrological associations, or personal meaning, birthstones continue to hold a special place in jewelry and cultural traditions. The diverse range of colors and origins ensures that there is a birthstone to resonate with every individual, offering a tangible connection to the natural world and the enduring power of symbolism.
