New Era Gems is proud to offer you this incredible array of top quality mineral specimens from around the world! For over 30 years Steve has acquired world class specimens directly from the source. This mineral's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. Don't let the picture size fool you. This is one of the biggest, 100% natural, pieces of pyrite we have in stock.
