37.75 Ct Loose Brazil Tourmaline-like Green Square Cut 20X20X15mm Lab Gemstone. This exquisite gemstone is a stunning addition to any collection. With a weight of 37.75 carats, this lab-created tourmaline-like gemstone boasts a beautiful green color and a square cut measuring 20x20x15mm. The gemstone is transparent and of excellent cut grade, making it perfect for use in jewelry and other decorative items. The gemstone is from Brazil and has not been enhanced, ensuring that it is in its natural state. It is loupe clean, meaning that it is free from any flaws that are visible to the naked eye. This gemstone is ideal for those looking for a unique and high-quality piece to add to their collection. The image shows a square-cut, bright green gemstone, possibly a lab-created tourmaline, or a similar gemstone like peridot or chrome diopside. Lab-created tourmalines are produced to replicate the natural gemstone's appearance and properties, offering an alternative to mined stones. Tourmalines are known for their wide range of colors, with the green variety often attributed to the presence of elements like iron, manganese, chrome, or vanadium. Paraiba tourmalines, known for their vivid colors, owe their hues to copper. Chrome diopside is another green gemstone that could resemble the one in the image, belonging to the pyroxene family and containing chromium. The square cut, as seen in the image, is a popular style that applies the same cutting technique to both sides of the gem.
