1.39 Ct. Purple Spinel from Ceylon (Sri Lanka)

This pear shape purple spinel from Ceylon is a refined and collectible gemstone, offered by The Natural Gemstone Company, and presented at a weight of 1.39 carats with precise dimensions of 8.87 x 6.31 x 3.96 mm. The stone is transparent, faceted in a mixed brilliant cut that combines the light performance of brilliant style facets with the elongated elegance of a pear outline. Its color intensity is described as intense, showing a rich and saturated purple that reads equally well in natural daylight and controlled indoor lighting environments. The gem has an excellent polish that enhances surface smoothness and allows each facet plane to act as a mirror, increasing overall brilliance and perceived depth. Importantly, this spinel has received no enhancement, preserving its natural origin characteristics and ensuring the color and clarity are entirely natural, a quality that discerning buyers rely upon when assessing value and provenance.

From a gemological perspective the structure and physical properties of spinel contribute directly to the visual qualities that set this stone apart. Spinel crystallizes in the isometric system, which means its crystal lattice is isotropic and transmits light uniformly from all directions. The refractive index for spinel typically falls in a tight range around 1.712 to 1.718, which combined with a specific gravity near 3.58 produces lively light return without excessive doubling or diffusion. Spinel is also single refractive, so it lacks pleochroism and presents a consistent hue across facets, which is particularly desirable in a mixed brilliant cut where light is returned in quick, bright flashes. With a Mohs hardness of approximately 8, spinel is robust enough for everyday wear in rings and pendants, and the durable crystal structure supports fine facet edges that maintain crisp reflections over time.

The cutting style and facet architecture of this pear shape spinel are central to its unparalleled sparkle, and the mixed brilliant design has been chosen to maximize scintillation and fire for this specific material. The arrangement of crown facets, pavilion facets, and the precise symmetry of the pear outline create multiple internal pathways for light to enter, reflect, and exit, producing the lively pinpoint flashes known as scintillation. The excellent polish minimizes surface scattering and allows for clean specular reflections, while the measured pavilion depth and table size in this cut favor high light return rather than light leakage. Because spinel is isotropic, the faceting geometry yields sharp contrast between bright and dark facets, which human vision perceives as sparkle, and the intense purple saturation benefits from the contrast, producing flashes that read as vivid violet and occasionally bluish violet under different viewing angles and light sources.

Clarity and origin further enhance the desirability and investment value of this gem. The clarity grade of very very slightly included, evaluated at eye level, indicates that the stone is essentially eye clean to most observers, with only minute inclusions that do not detract from transparency or brilliance. These small internal characteristics are typical of natural spinel and often serve as internal fingerprints that confirm natural formation, especially when paired with confirmed Sri Lankan origin. Ceylon spinels are historically respected for their vibrant colors and clean material, and provenance from Sri Lanka adds an extra layer of pedigree for collectors. For buyers seeking a gemstone that balances scientific rigor with visual appeal, this 1.39 carat pear purple spinel represents a compelling option, and The Natural Gemstone Company stands behind its natural origin, uncompromising polish, and excellent cut as evidence of a gem selected for both beauty and lasting value.
