Tourmaline Introduction

Tourmaline, known as "tourmaline" in English, comes from the ancient Sinhalese word *Turamali*, meaning "mixed gems." This beautiful gemstone has a rich history and is often associated with legends. According to an old tale, if you could find the starting point of a rainbow, you would discover eternal happiness and wealth. Though rainbows are common, their beginning remains elusive—until 1500, when a Portuguese expedition team discovered a remarkable gem in Brazil. It shimmered with vibrant, neon-like colors, as if a rainbow had fallen from the sky into the earth. This ordinary stone, bathed in the light of the rainbow, gained a variety of dazzling hues and became a treasured treasure. Not all stones share such fortune. The gemstones found at the base of the rainbow were later named "Tourmaline," and they are also called "the rainbow that fell to Earth." Today, tourmaline is grouped with other colored gemstones like rubies, sapphires, chalcedony, tanzanite, and emeralds. These natural gems are highly popular among the public and hold significant value. In Chinese history, the term "Bixi" first appeared during the Qing Dynasty. Classical texts from that era mention "Biya," which was used in various records. One text, *Shiya*, notes: "The name 'Biyia' is mentioned in Chinese literature, though not widely published. The Qing Dynasty's *Plan Cloud* states that 'Douya uses Biya.' *Dianhai Yuhengzhi* describes 'Bixia' and 'Bixi,' while *Yuji* also refers to 'Bixiaxi.' Today, the world calls it 'Biyia' or 'Bixi,' but its origin remains unclear, likely derived from a foreign dialect." After the Qing Dynasty, historical records also mention names like "Piselenium," "Bixi," and "Bixiaxi." In modern times, this unique gem is known as tourmaline. Legend has it that Empress Dowager Cixi of the Qing Dynasty adored tourmaline. Many of her jewels contained rare varieties, including the famous watermelon tourmaline. Today, many Chinese people still cherish jewelry made from tourmaline. The demand for tourmaline has risen, and many people choose to gift custom-made tourmaline pieces to loved ones. There are numerous styles available, such as tourmaline bracelets, rings, pendants, and more. Whether for personal use or as a meaningful gift, tourmaline continues to captivate hearts around the world.
