The stone, called chalcedony, is actually a derivative of quartz (SIO 2) with a microcrystalline texture. Chalcedony still holds an important place in the antique jewelry of the world. Chalcedony played an important role in Mesopotamian, Hittite, Egyptian, Hellenistic, and Roman cultures. In Roman times, they were transported from the port of Kadiköy, now Istanbul, to new ports where they eventually became part of ancient jewelry. Chalcedony takes its name from the Kadiköy district, which was called Chalcedon at the time.

Known as the “blue gold” of Anatolia, this stone usually ranges in shades of blue from very light to very dark blue, almost white. mRarely, it is also found in a medley of colors, a mixture of brown and yellow, called chalcedony agate. The Romans believed that chalcedony protected them from negative energy, regulated their memotions, and brought them good luck, so they carved it into magical amulets, seals, miniatures, and jewelry, including rings, pins, bracelets, and necklaces.

With the fall of the Roman Empire, chalcedony lost its appeal as a decorative stone and disappeared from jewelry world for the time being. However, with the Renaissance and the birth of classicism, chalcedony’s powerful energy, unique nuances, and elegant appearance reappeared. Along with other colored stones such as carnelian, agate, sapphire, etc., chalcedony became an object of desire for aristocrats in luxurious and elegant jewelry. Today, chalcedony is still one of the most beloved decorative stones and a popular mineral used in all kinds of men’s and women’s jewelry.
