The green emerald is a gemstone that is typically considered a precious stone rather than a semiprecious stone due to its rarity and high value. Emeralds are not recommended for exterior applications in cold climates, especially in areas with significant temperature fluctuations. This is because emeralds are relatively soft and brittle gemstones, ranking 7.5 to 8 on the Mohs scale of hardness. They are prone to cracking or chipping under extreme temperature changes or physical stress. Furthermore, emeralds are not as resistant to weathering and general wear as some other stones that are more suitable for exterior use. They can lose their luster, clarity, and color over time when exposed to harsh weather conditions, ultraviolet radiation, and pollutants. For exterior applications in cold climates, it is generally recommended to use more durable and resilient stones such as granite, quartzite, or certain types of marble that are more resistant to freezing, thawing, and general wear. These stones are better equipped to withstand the harsh conditions and maintain their beauty and structural integrity over time.

Yes, green emerald semiprecious stones can be used outdoors, but they may require extra care and maintenance to preserve their beauty and durability. Emeralds are a relatively softer gemstone compared to others, and they have a tendency to chip or scratch easily. Therefore, if you plan to use emeralds in an outdoor setting, such as as a pavement or in a fountain, it is important to ensure that they are properly protected and installed to prevent damage from elements, foot traffic, or excessive wear. It is recommended to consult with a professional jeweler or stone specialist for guidance on using emeralds in outdoor applications.
