 this 6.60 ct unheated lavender blue spinel was carefully planned, cut, and polished into a clean cushion gemstone above 2.60 ct. Its soft lavender blue color and gentle violetish pink shift reveal the hidden character of natural spinel.

What is a Ceylon Natural Cobalt Blue Spinel? It is a natural spinel colored by trace elements that create a rare and vivid blue presence, often with a slightly violetish character depending on tone and light. Unlike many better-known blue gemstones, spinel belongs to its own mineral species and is admired for its natural brilliance, excellent durability, and rarity in fine blue colors. In this case, the gemstone is a GIC-certified Natural Cobalt Spinel from Sri Lanka, weighing 6.07 carats and presenting a refined violetish blue appearance in a well-proportioned octagon cut.

This loose faceted gemstone measures 12.94 x 8.92 x 6.15 mm and shows transparent clarity with a VS grade, placing it in a highly desirable category for fine jewelry or advanced gemstone collecting. The cut style is elegant and architectural, with rectangular step-cut character and truncated corners that create a sophisticated octagon outline. This shape allows the stone to display calm depth, internal richness, and controlled flashes of blue rather than only surface sparkle. The result is a gemstone that feels powerful, composed, and distinctly luxurious.

Gemologically, spinel is a separate species from sapphire and belongs to the cubic crystal system, which means it is singly refractive and often admired for its clean optical personality. Fine cobalt-bearing blue spinels are especially rare because the color chemistry required to produce a strong blue without turning too gray or too dark is highly uncommon in nature. When a stone reaches over 6 carats with a high-quality appearance, transparent body, and balanced cut, the collector appeal becomes even stronger.

This gemstone comes from Ratnapura village around mining in Sri Lanka, a source region internationally respected for producing important colored stones. Sri Lankan spinels are valued for their lively colors and clean crystal character, and in rare cases, exceptional blue material appears with a tone that stands apart from ordinary commercial stones. That is what gives this cobalt blue spinel its identity. It is not simply blue. It carries a violetish blue depth that feels elegant, mature, and uncommon.

Treatment disclosure is equally important. This stone is presented as natural and unheated, and the accompanying GIC certification identifies it as Natural Spinel, Cobalt Spinel. For collectors and connoisseurs, certification adds confidence, not because the beauty needs explanation, but because rarity deserves documentation. In a market where many buyers seek both visual impact and gemological integrity, a certified cobalt blue spinel from Sri Lanka represents a serious and refined choice.

In traditional belief systems, blue spinel is sometimes associated with peace, harmony, truth, and emotional balance, and it is also linked by some with the throat chakra and calm communication. These are cultural and symbolic associations rather than scientific guarantees, but they add another layer of meaning for those who appreciate gemstones beyond appearance alone.

1.44 ct of refined greenish-blue brilliance, cut in a precise octagon shape with exceptional clarity and luster.

Unheated and sourced directly from Rakwana village around mining in Sri Lanka, this gemstone reflects true origin, balance, and quiet elegance.

True gemstones are not simply discovered — they are experienced. This Ceylon Natural Greenish-Blue Spinel is a perfect example of how nature, patience, and ethical sourcing come together to create something timeless.

Sourced directly from Hangamuwa village in the Sabaragamuwa Province of Sri Lanka, this spinel began its journey as a 4.73 carat natural, unheated rough, found through traditional village-based mining. These regions are not industrial mining zones — they are places where gemstones are uncovered carefully, with respect for the land and generations of local knowledge.

Before cutting, the rough crystal showed strong internal potential, but also required deep understanding to preserve its character. Through precise lapidary work, the stone was transformed into a 1.65 carat hexagon-cut spinel, measuring 7.22 × 8.38 × 4.30 mm, revealing a refined greenish-blue hue with remarkable depth and balance.

This stone is completely natural and unheated, with a VVS clarity grade, placing it among the higher-quality spinels available today. Its hexagonal cut is not chosen for trend — it is chosen to respect the crystal’s natural geometry, maximizing light return while maintaining weight integrity.

Certified by CSL – Colored Stone Laboratory, the gemstone carries documented assurance of authenticity, origin, and treatment status.

At Danu Group, we do not believe gemstones are commodities. When you acquire a stone like this, you are not just buying a gem — you are connecting to its origin, its miners, and its journey from the earth to your hand.

This Greenish-Blue Spinel symbolizes peace, clarity, harmony, and emotional balance, traditionally associated with the Throat Chakra and linked astrologically to Saturn, Capricorn, and Aquarius. Whether worn as jewelry or kept as a collector’s stone, its value goes far beyond appearance — it lies in its story.

Sri Lanka has long been recognized as one of the world’s most important sources of fine gemstones, and among its lesser-seen treasures is the naturally occurring grayish-violet spinel. This exceptional 1.57 ct Ceylon Natural Spinel is a refined example of how nature, source, and cutting decisions come together to create rarity and value.

This spinel originates from Nivithigala village around mining in Sri Lanka, an area known for producing spinels with complex internal color zoning rather than flat, single-tone saturation. The original rough weighed 8.87 carats, measuring 14.5 × 11.5 × 5.5 mm, and was completely natural and unheated.

In its rough state, the crystal displayed a distinctive mix of grayish-violet and blue color zones, along with visible white smoky areas and minor inclusions. While it was technically possible to retain more weight and achieve a larger finished stone, Danu Group made a conscious decision to prioritize clarity and refinement over size. By carefully removing all smoky areas and inclusions during cutting, the final result is a loupe-clean gemstone, finished at 1.57 carats.

The finished spinel is precision-cut in an octagon shape, measuring 6.69 × 5.91 × 4.50 mm, enhancing its symmetry, brilliance, and color balance. Under natural daylight, the stone often presents a blue spinel appearance, while indoor or controlled lighting reveals its true grayish-violet character. This optical behavior is entirely natural and caused by the stone’s internal color zoning—an uncommon and highly collectible feature among fine spinels.

Ceylon Natural Blue Spinel is one of Sri Lanka’s most elegant gemstones, admired for its refined color, durability, and natural brilliance. This exceptional 1.44 carat greenish-blue spinel represents the true journey of a gemstone that comes directly from the source, without unnecessary intermediaries. Carefully sourced, cut, and presented by Danu Group, this stone reflects both gemological integrity and responsible trade practices.

The story of this gemstone begins in Nivithigala village around mining in Sri Lanka, where the original rough spinel weighing 5.08 carats was recovered through traditional alluvial mining methods. These mining areas are deeply connected to local communities, where stones are extracted with generations of experience and intimate knowledge of the land. By working closely with trusted miners and suppliers, Danu Group ensures transparency in origin and ethical sourcing at every stage.

After careful evaluation, the rough was skillfully transformed into a 1.44 carat octagon-cut spinel, measuring 7.56 × 5.84 × 3.76 mm. The cutting process was designed to preserve natural weight while enhancing brilliance and color balance. The result is a loup-clean, high-quality gemstone with a refined greenish-blue tone and excellent light performance.

This spinel is natural and unheated, a key factor for collectors and fine jewelry designers seeking authenticity. Its identity and natural status are confirmed by CSL – Colored Stone Laboratory, adding confidence and long-term value.

Because the stone is completely natural and unheated, its internal energy and optical properties remain untouched, making it highly desirable for collectors, designers, and investors seeking authenticity and rarity.

This gem displays VVS clarity, allowing uninterrupted brilliance across the table and crown facets.

The final result is a visually powerful stone with excellent proportions, brilliance, and aesthetic balance.
