Gemologist’s Notes

This specimen exhibits the distinct "neon" saturation unique to copper-bearing tourmalines. While the clarity is graded as moderate, the inclusions are typical for this species and do not detract from the stone's remarkable "glow" under natural light. Its 8.1 mm length provides the visual impact of a much larger stone, making it an exceptional center-stone candidate for a bespoke ring or a striking pendant.

Investment Potential

As the supply of copper-bearing tourmalines from both Brazil and Mozambique becomes increasingly constrained, stones of this saturation and size continue to see strong market demand. Ref: PAR 41B represents a prime opportunity to own a piece of the "Paraiba legacy."

Since you have the specific measurements and origin, here is an evaluation of what makes this stone unique and how to best showcase it:

Gemstone Analysis

• Color & Origin: Mozambique Paraibas are celebrated for their "neon" or "electric" glow, caused by copper and manganese. While Brazilian stones are the historical standard, Mozambican gems like yours often offer better clarity and larger sizes while maintaining that iconic turquoise-to-blue saturation.

• Dimensions & Cut: An 8.7 mm length is quite generous for under 2 carats. The Mixed Cut (usually a brilliant crown and step-cut pavilion) is a smart choice for Tourmaline, as it maximizes brilliance while maintaining the depth of color.

   

• Clarity: "Moderate" clarity is very common for Paraibas. Because they are "Type III" gemstones, they are expected to have some inclusions. In this vivid blue hue, these internal characteristics often blend into the "glow" of the stone.

Design Recommendations

To protect your investment and highlight that electric blue color, consider these setting styles:

Care Note

Tourmalines have a hardness of 7 to 7.5 on the Mohs scale. While durable enough for daily wear in a ring, they are sensitive to high heat and sudden pressure. It is best to avoid ultrasonic cleaners; a simple solution of warm, soapy water and a soft brush is the safest way to keep that neon glow bright.

Experience the rare, "swimming pool blue" glow of this 1.15-carat Paraiba Tourmaline. While many copper-bearing tourmalines lean toward green, this specimen showcases a highly coveted Blue primary hue. Originating from the prestigious mines of Mozambique, this gem captures the "electric" essence that has made Paraiba the most famous tourmaline variety in history.

With a length of 7.8 mm, this stone offers the visual impact of a much larger gem, making it an ideal candidate for a centerpiece luxury ring.

The "Electric Blue" Advantage

While the clarity is moderate, these natural internal characteristics are typical of the copper-rich environment where these stones form. When set in white gold or platinum, the "neon" blue of this Mozambique specimen becomes even more pronounced, creating a striking contrast that is impossible to ignore.

Investment Note: Since the start of 2026, demand for "Blue" Paraiba has outpaced supply. Finding a stone over 1 carat with this level of color intensity is a significant addition to any high-end inventory.

The Green hue of this Mozambique specimen is vivid and "electric," maintaining its glow even in dim lighting—a hallmark of the "neon" Paraiba effect. Its ensures the color is rich and saturated throughout the stone.

The Allure of Mozambique Paraiba

While Brazilian Paraiba is legendary, the high-quality deposits from Mozambique have become the gold standard for collectors seeking larger, Eye Clean specimens. Finding a Paraiba at nearly a full carat ($0.96\text{ct}$) that is free of eye-visible inclusions is a true rarity; most copper-bearing tourmalines are naturally "sleepy" or heavily included.

While many Axinite specimens are "included" or muddy in tone, this gem is exceptionally Eye Clean, allowing its sophisticated color-shift phenomenon to take center stage.

• Clarity: Eye Clean (Ultra-transparent)

• Cut: Mixed

Why This Gemstone is a Collector's Find

Magnesio-Axinite is a "connoisseur’s stone," prized for its high refractive index and its distinct pleochroism. Finding a specimen that is Eye Clean at under one carat is actually quite difficult, as smaller crystals often break during the cutting process due to the mineral's natural cleavage.

The cushion cut makes this an ideal candidate for a delicate "misty blue" accent stone or a sophisticated custom ring that reveals its pinkish secret only when the sun goes down.

Expert Insight: Unlike the more common Ferro-axinite, the Magnesium-rich variety is significantly rarer and sought after for its unique color-shifting properties—an essential addition to any "Phenomenal Gem" collection.

Why This Gemstone is a Standout

Magnesio-Axinite is one of the most sought-after "exotic" gemstones in the world, often found in the famous Merelani Hills of Tanzania. Finding an Eye Clean specimen at 1.54 carats is a significant achievement, as this species often presents with fine, hair-like inclusions.

The cushion cut provides a soft, classic silhouette that works beautifully in a bespoke "Toi et Moi" ring or as a striking solitaire. Its high refractive index ensures that the stone remains bright and lively in all lighting conditions, shifting its hue effortlessly as you move from natural sunlight to evening lamplight.

Investment Note: Collectors of "rare species" prioritize Magnesio-Axinite for its high luster and unique color-shift profile. Clean stones with a clear blue-to-pink transition are increasingly difficult to source in today’s market.

Presenting a true curiosity of the mineral world: a 2.37-carat Magnesio-Axinite with a dramatic "day-to-night" personality.

The pear shape is particularly effective for this species, as it highlights the gem's strong pleochroism—the ability to show different colors from different angles—alongside its primary color-change phenomenon.

A Collector’s Treasure

What makes this stone a "museum-grade" specimen is the combination of its size and clarity. Magnesio-Axinite is notoriously difficult to find in "Eye Clean" quality; most crystals are heavily included or only found in small shards. At 2.37 carats, this stone offers a significant face-up presence that makes it a perfect centerpiece for a custom-designed pendant or an avant-garde engagement ring.

Beyond its color change, this stone is a "phenomenal" gem in every sense—it is both pyroelectric (generates electricity when heated) and piezoelectric (generates electricity under pressure), making it as scientifically fascinating as it is beautiful.
