3.72 Ct. Tourmaline from Madagascar

When you are searching for a gemstone that answers both the heart and the practical senses, this transparent 3.72 carat asscher octagon bluish green tourmaline from Madagascar is the kind of find that quietly ends the search, and The Natural Gemstone Company is proud to present it to you. The stone measures 8.60 by 8.35 by 7.15 mm, a comfortable and striking size for a center stone in an engagement ring, a memorable pendant, or an heirloom piece destined for daily wear. The medium intense bluish green color has balanced saturation and a lively tone that reads sophisticated in daylight and glows warmly under indoor light. The asscher cut, with its step facets and clean octagonal outline, gives the gem a classic, architectural presence that flatters both modern minimalist settings and vintage inspired designs. Heat treated to subtly optimize hue and clarity, this tourmaline retains natural character with excellent polish and a clarity grade of eye clean when evaluated at eye level, so the surface sparkles without distraction and the internal transparency invites focused admiration.

Beyond the color and cut, the way this tourmaline interacts with light makes it feel alive on the finger or in a necklace. The asscher faceting creates a hall of mirrors effect, emphasizing broad flashes of color and depth, while the octagon outline gives crisp, elegant lines that suit a range of mounting styles. Because the gem is transparent and eye clean, light penetrates deeply and returns as lively, even tone and soft scintillation rather than scattered sparkle, which is ideal for someone who prefers refined brilliance over brash fire. The excellent polish enhances every facet junction so that each turn of the wrist reveals fresh planes and subtle shifts from blue toward green depending on the light source, making the gem both versatile and engaging. These optical qualities come together to create a gemstone that is both wearable art and a meaningful symbol, suitable for daily use while still feeling special.

Durability is often the deciding factor when choosing a gemstone for everyday jewelry, and tourmaline is a strong candidate for frequent wear. With a Mohs hardness around seven to seven and a half, this tourmaline stands up well to routine handling and the minor abrasions that happen with daily life, while its fair to good toughness means it resists breakage under normal wear conditions. The asscher cut with its step facets and more substantial pavilion also contributes to durability, because the faceting pattern and the relatively even thickness through the stone reduce the risk of vulnerable thin points. For added peace of mind, consider setting styles that protect the corners and girdle, such as a secure four or eight prong setting with protective prong tips, a bezel setting that wraps the outline for maximum protection, or a semi bezel that preserves the sharp asscher profile while shielding the edges. Because this tourmaline has been heat treated to enhance color, it is stable under ordinary wear and light exposure, however, as with all fine colored gems, avoid prolonged exposure to extreme heat or harsh chemicals, remove the piece for heavy manual work, and clean with warm soapy water and a soft brush or a gentle jewelry cleaning solution recommended by The Natural Gemstone Company.

Choosing this Madagascar tourmaline means selecting more than a beautiful stone, it means choosing an item that integrates beauty, practicality, and provenance into a piece you can enjoy every day. Madagascar is renowned for producing tourmalines with vivid, natural tones and this gem showcases that pedigree with its medium intense bluish green color and transparent, eye clean clarity. At The Natural Gemstone Company we stand behind the authenticity and careful treatment disclosure of each stone, and we welcome conversations about custom settings that will both flatter the asscher octagon form and maximize protection for daily wear. Whether you imagine this gem as the central symbol in an engagement ring, a statement pendant you will reach for every morning, or a treasured addition to a collection, its combination of size, polish, cut, and durability makes it an ideal solution for those who want a rare and wearable gemstone.
