No returns or refunds, so ask all questions before buyingLOW QUALITYLouisiana Opal is considered one of the rarest types of opal due to its limited source in Vernon Parish and a single commercial mine that is now closed. This rare precious opal is formed in sandstone, with sand grains cemented together by opal, and its colors are only visible when polished. While black opal is often cited as the rarest, Louisiana opal is notable for its rarity and unique geological formation.
