Blue Goldstone is a type of synthetic glass that is often mistaken for a natural gemstone due to its glittering appearance. It is also known as “Blue Sandstone”. The name “Blue Goldstone” is derived from the sparkling metallic copper flecks suspended within the deep blue or purplish glass, giving it a resemblance to a starry night sky. Blue Goldstone is NOT a naturally occurring mineral but rather a synthetic, man-made, glass-like material crafted through human ingenuity.
