透长石是钙钠 inosilicate 矿物，化学式为 NaCa₂Si₃O₈(OH)。它形成针状至纤维状的集合体，在晶型良好的标本中可呈现丝质到玻璃光泽。蓝色品种拉里玛尔（larimar）因铜引起的着色而闻名，几乎仅在多米尼加共和国巴拉奥纳地区发现，在那里强烈的蓝色基调可与白色纹线形成对比。

- Pectolite is a calcium sodium inosilicate mineral with the formula NaCa₂Si₃O₈(OH). Its most famous variety is larimar, a rare blue form found almost exclusively in the Dominican Republic. Stability Physical Stability: Pectolite is relatively brittle and has perfect cleavage, meaning it breaks easily. It scores about 4.5–5 on the Mohs scale, so it's not ideal for wear in jewelry unless protected. Chemical Stability: It is not highly reactive, but like many silicates, can be mildly affected by acids and prolonged water exposure. Larimar, for instance, may show surface dulling or etching if exposed to chemicals or harsh conditions. Rarity As a species: Pectolite itself is not rare and occurs in many localities worldwide, including the U.S., Canada, Italy, and Russia. As a crystal specimen: Well-formed, translucent to transparent crystals are uncommon and can be highly sought after by collectors. Most pectolite is fibrous or massive. Larimar (blue variety): Very rare, found almost exclusively in a single locality in the Barahona province of the Dominican Republic. The intense blue coloration is due to copper substitution and is highly prized.

关于针钠钙石
收藏者寻求晶体形态良好、半透明至透明的结晶体以及引人注目的蓝色拉里玛尔块用于展示和组合标本。除拉里玛尔外，透长石在全球各地的矿区也有出产，包括美国、加拿大、冰岛、意大利和俄罗斯等，常以在玄武岩性或热液环境中的纤维状集合体形式出现。尽管该矿物本身相对稳定但较脆，具有解理，经过小心处理并在保护壳中陈列可凸显其脆弱的美。原生晶体形态的稀少以及拉里玛尔色彩的魅力，使其在收藏者中形成独特的吸引力，尤其是那些看重独特着色与产地多样性的收藏者。
