Green tourmaline is a captivating gemstone that has gained popularity in the world of jewelry. This beautiful stone belongs to the tourmaline family, known for its wide range of colors and unique properties. The green variety, in particular, is cherished for its vibrant hues, which can vary from light green to deep forest green. This article will explore the characteristics, cutting styles, and care of green tourmaline, with a special focus on the emerald cut.
What is Tourmaline?
Tourmaline is a complex silicate mineral that comes in a variety of colors. Its name derives from the Sinhalese word “turmali,” which means “mixed gems.” This is fitting, as tourmaline can exhibit multiple colors within a single crystal. It is a boron silicate mineral, often containing aluminum, iron, magnesium, and other elements.
The Formation of Tourmaline
Tourmaline forms in igneous and metamorphic rocks. It can be found in granite pegmatites and can also occur in sedimentary rocks. The presence of different elements during the formation process leads to the wide variety of colors seen in tourmaline. Green tourmaline, specifically, is often colored by the presence of iron and chromium.
What are the Characteristics of Green Tourmaline?
Green tourmaline is characterized by its vibrant color and unique optical properties. Here are some key characteristics:
Color
The color of green tourmaline can range from a light, almost pastel green to a deep, rich green. The most prized shades are those that resemble emeralds, with a vivid and saturated tone. The color can also exhibit pleochroism, meaning it may appear different when viewed from different angles.
Clarity
Green tourmaline is typically found with good clarity. However, like many gemstones, it can have inclusions. These inclusions can affect the stone’s brilliance and overall appearance. Higher-quality stones with fewer inclusions are more valuable.
Cut
The cut of a gemstone significantly impacts its visual appeal. Green tourmaline can be cut into various shapes, but the emerald cut is particularly popular. This cut enhances the stone’s color and clarity while providing a unique and elegant look.
Hardness
On the Mohs scale of hardness, tourmaline ranks between seven and seven and a half. This makes it a durable choice for everyday wear in jewelry. However, it is still advisable to handle it with care to avoid scratches or damage.
Refractive Index
The refractive index of green tourmaline ranges from one point six one to one point six four. This property contributes to the stone’s brilliance and sparkle. The higher the refractive index, the more the stone can bend light, enhancing its visual appeal.
Why Choose the Emerald Cut for Green Tourmaline?
The emerald cut is a popular choice for many gemstones, including green tourmaline. This cut is characterized by its rectangular shape and stepped facets, which create a unique optical effect. Here are several reasons why the emerald cut is particularly suited for green tourmaline:
Enhancement of Color
The emerald cut allows for a larger surface area, which enhances the color of the green tourmaline. The step-cut facets reflect light in a way that showcases the stone’s rich green hues.
Showcasing Clarity
The open facets of the emerald cut allow for better visibility into the stone. This means that any inclusions or imperfections are more easily seen, making clarity a critical factor in the selection of a green tourmaline with an emerald cut.
Timeless Elegance
The emerald cut is a classic and timeless choice. Its elegant lines and sophisticated appearance make it a favorite among those who appreciate understated beauty. This cut pairs well with various settings, from modern to vintage.
Versatility in Jewelry Design
Emerald-cut green tourmalines can be used in various jewelry pieces, including rings, pendants, and earrings. Their unique shape and color make them versatile enough to complement different styles and settings.
How is Green Tourmaline Cut?
Cutting green tourmaline requires skill and precision. The process involves several steps:
Selecting the Rough Stone
The first step in cutting green tourmaline is selecting the rough stone. Gem cutters look for pieces with good color, clarity, and size. The quality of the rough stone will ultimately determine the quality of the finished product.
Planning the Cut
Before cutting, gem cutters carefully plan the cut to maximize the stone’s potential. This involves considering the color distribution, size, and shape of the rough stone. For emerald cuts, the focus is on creating a rectangular shape with step facets.
Shaping the Stone
Once the plan is in place, the gem cutter begins shaping the stone. This involves removing excess material to create the desired shape. For emerald cuts, this means creating a rectangular outline.
Faceting
After shaping, the cutter will facet the stone. This process involves creating the flat surfaces that reflect light. The emerald cut features step facets, which are wider and flatter than those found in brilliant cuts.
Polishing
The final step is polishing the stone to enhance its luster and brilliance. This is a meticulous process, as the quality of the polish will affect how the stone appears once set in jewelry.
What Are the Popular Settings for Emerald-Cut Green Tourmaline?
Emerald-cut green tourmaline stones can be set in various styles, each enhancing the stone’s beauty in different ways. Here are some popular settings:
Solitaire Settings
A solitaire setting features a single emerald-cut green tourmaline, allowing the stone to take center stage. This setting is classic and elegant, perfect for an engagement ring or a statement piece.
Halo Settings
Halo settings surround the central stone with smaller diamonds or other gemstones. This design enhances the overall sparkle and draws attention to the emerald-cut green tourmaline. It creates a stunning contrast between the vibrant green and the brilliance of the surrounding stones.
Three-Stone Settings
Three-stone settings feature an emerald-cut green tourmaline flanked by two smaller stones. This design symbolizes the past, present, and future, making it a popular choice for anniversary rings or meaningful gifts.
Vintage Settings
Vintage-inspired settings often incorporate intricate details and filigree work. An emerald-cut green tourmaline in a vintage setting can evoke a sense of nostalgia and timeless beauty.
Modern Settings
Modern settings focus on clean lines and minimalistic designs. An emerald-cut green tourmaline can be beautifully showcased in a sleek, contemporary setting, appealing to those who prefer a more modern aesthetic.

Regular cleaning is important to keep green tourmaline looking its best. Use warm, soapy water and a soft brush to gently clean the stone. Avoid harsh chemicals and ultrasonic cleaners, as they can damage the stone.
Storage
When not wearing green tourmaline jewelry, store it in a soft pouch or a separate compartment in a jewelry box. This prevents scratches and damage from other pieces.
Avoiding Hard Impacts
Although green tourmaline is relatively durable, it is still susceptible to chipping and scratching. Avoid exposing it to hard impacts or rough surfaces.
Regular Inspections
Periodically inspect your green tourmaline jewelry for any loose stones or damage. If you notice any issues, take it to a professional jeweler for repair.

What is the Value of Green Tourmaline?
The value of green tourmaline depends on several factors, including color, clarity, cut, and carat weight. Here’s a breakdown of how these factors influence value:
Color
Color is one of the most important factors in determining the value of green tourmaline. Stones with a rich, vivid green color are more valuable than those with lighter or less saturated hues.
Clarity
Clarity refers to the presence of inclusions or blemishes within the stone. Higher clarity stones, which are free from visible inclusions, are more valuable. However, some inclusions can be acceptable if they do not significantly affect the stone’s appearance.
Cut
The quality of the cut affects how well the stone reflects light. Well-cut stones that enhance the color and brilliance of the green tourmaline are more valuable.
Carat Weight
As with most gemstones, larger stones are generally more valuable. However, the price per carat can vary based on the quality of the stone. A high-quality smaller stone may be worth more than a larger stone with lower quality.
Origin
The origin of the stone can also impact its value. Stones from well-known sources, such as Brazil or Afghanistan, may carry a premium due to their reputation for quality.
