2.05 Ct. Blue Spinel from Ceylon (Sri Lanka)

This specimen is a transparent blue spinel weighing 2.05 carat, presented in a classic emerald cut profile. The cutting dimensions are 8.24 by 6.59 by 4.71 mm, producing a total depth that measures approximately 63.5 percent of the average girdle span. The gem originates from Ceylon Sri Lanka, and it is supplied by The Natural Gemstone Company with no enhancement, untreated and natural. Clarity is graded very slightly included, evaluated at eye level, and the parcel of inclusions is minimal enough that transparency remains the dominant attribute. Color intensity is described as dark, which in this material yields a saturated deep blue that reads almost inky in diffused light, while flashes of brighter blue emerge under direct illumination. The polish is excellent, allowing the broad table and step facets to present crisp facet junctions and strong facet reflection.

From a faceting perspective the emerald cut employed here emphasizes directional light performance and color distribution rather than overt brilliance. The step faceting produces broad, parallel facets on the crown and pavilion that create a hall of mirrors effect, which is particularly effective for a dense, dark blue spinel because it concentrates color towards the center while permitting controlled flashes along the facet planes. The cutter preserved weight by maintaining an ample pavilion depth, which contributes to the stone remaining above two carat weight while retaining pleasing proportions. The broad table and carefully managed crown angle ensure even color zoning and reduce windowing, so light returns as tonal depth rather than as dispersed sparkle. The excellent polish and tight symmetry are evident in the facet meeting points and in the consistent reflection banding visible along the pavilion facets.

Weight is a primary determinant of value and rarity for colored gemstones, and at 2.05 carat this blue spinel occupies an important threshold in the market. Spinel supply diminishes rapidly as size increases in well saturated colors, making stones above two carat significantly rarer on a per carat basis than smaller material. Because market pricing for gemstones typically escalates nonlinearly with size, this specimen commands a premium not only for its color and origin, but for the fact that it is natural and unenhanced. The combination of dark intensity and eye level clarity produces a visual presence that a smaller or more heavily included stone would lack, so the per carat valuation of this piece reflects both optical performance and scarcity. Origin from Ceylon Sri Lanka further enhances provenance appeal, as Sri Lankan spinel is historically sought for its stable deep blues and clean crystal habit.

For practical use and setting, the stone is resilient with a gem hardness around eight on the Mohs scale and a refractive index approximately 1.72, so it can be securely set in rings or pendants with standard protective design considerations. The emerald cut profile favors gallery and bezel design that protect the corners and emphasize the broad table, while a white metal mounting such as platinum or 18 carat white gold will maximize the perception of depth and coolness of tone, and a yellow metal mount will introduce contrast that can warm the perceived tone. We can provide detailed imaging, a gemological report upon request, and bespoke setting recommendations. The Natural Gemstone Company stands behind the accuracy of the description, and we welcome direct inquiries regarding certification, high resolution imagery, and advice on settings that will showcase the rarity and visual impact afforded by this 2.05 carat Ceylon blue spinel.
