This listing is for a genuine Green Tremolite crystal sourced from the
world-famous Merelani Hills, Tanzania. Tremolite is a rare member of the amphibole group of inosilicate minerals, known for its long, slender prismatic crystals and fibrous or bladed structures. The vibrant green hue is caused by trace amounts of chromium or iron.Tremolite from Merelani Hills is highly sought-after due to its association with tanzanite and its rarity in collectible, gem-quality form. This carefully selected piece displays classic fibrous and elongated prismatic crystal habits with a rich green colour that distinguishes it from other localities.Each specimen is the actual piece you will receive, with a scale cube (1cm) included in the photo for sizing reference.All of our Crystals are 100% Genuine Specimens & come with a Certificate of Authenticity.
