What is a Dark Blue Stone?

A ‘dark blue stone’ is a broad category encompassing various gemstones and minerals that exhibit a deep, rich blue coloration. This hue can range from a sapphire’s intense royal blue to the more subdued tones of lapis lazuli or sodalite. The value and appeal of a dark blue stone are determined by several factors, including its color intensity, clarity, cut, carat weight, and origin. In China, and particularly in the Nanjing region, a variety of dark blue stones are sought after for their aesthetic beauty and industrial utility. These stones often possess unique geological properties that make them suitable for jewelry, ornamental objects, and even specialized technological applications. Understanding the specific mineral composition and characteristics of each type of dark blue stone is crucial for identifying its true worth and potential uses. The geological formations in and around China, including the rich mineral deposits accessible from Nanjing, provide a diverse palette of these coveted blue gems.

Beyond their symbolic meanings, many dark blue stones are prized for their durability and luster, making them ideal for everyday wear and long-term display.
