What is Chalcedony Xanh Lam?
Chalcedony xanh lam is a type of microcrystalline quartz that displays a distinct blue color.

The blue hue in chalcedony xanh lam ranges from light sky blue to deeper shades, often exhibiting a subtle translucency that gives the stone a calming visual effect. This gemstone is prized not only for its beauty but also for its durability, making it suitable for a variety of applications.
Composition and Structure
Chalcedony xanh lam is composed primarily of silicon dioxide (SiO2), like other types of quartz. Its microcrystalline structure consists of tiny interlocking quartz crystals, which contribute to its smooth texture and resistance to breakage. The blue coloration is usually caused by trace amounts of minerals or microscopic inclusions that interact with light to produce a soft, uniform color. Unlike more transparent gemstones, chalcedony xanh lam has a waxy to vitreous luster, adding to its unique charm.
