0.70 Ct. Greenish Blue Spinel from Ceylon (Sri Lanka)

This greenish blue spinel offered by The Natural Gemstone Company is a remarkable example of natural, untreated material, weighing 0.70 carat, and measuring 6.33 x 4.57 x 3.07 mm. The oval outline with a mixed brilliant cut has been executed to balance color and brilliance, the shallow crown and well angled pavilion facets creating a lively play of light while maintaining a generous table to display the stone color. Clarity has been evaluated at very slightly included at eye level, meaning that the gem is transparent and bright to unaided sight, with only minor internal features that do not detract from face up beauty or durability. The polish is excellent, which enhances facet recovery and overall light return, and the intense color intensity is a defining quality for collectors and connoisseurs who prize saturated tones in spinel. The lack of any enhancement is an important attribute, many buyers prefer natural, unheated stones, and this example from Ceylon Sri Lanka carries the historical reputation of that locality for producing high quality spinels and sapphires, adding provenance value for informed purchasers.

From a gemological perspective spinel is an attractive option for everyday wear because it is isometric and optically isotropic, which means it shows consistent color from all viewing angles and no pleochroism, this stability in appearance is reassuring when setting the stone into a piece that will be seen from multiple directions. With a hardness near 8 on the Mohs scale, spinel offers robust wearability compared with softer alternatives, it is well suited to rings pendants and everyday earrings when set with proper protection. The mixed brilliant cut on this oval has been chosen to maximize scintillation while preserving depth for color, the proportions given provide a pleasing balance between brightness and saturation. For an educated buyer who evaluates proportion clarity polish and origin, the combination of intense Ceylon color no treatment and very slightly included clarity represents a strong value proposition, particularly for those assembling a collection of natural gemstones with distinct provenances.

When planning a custom design this greenish blue oval spinel adapts beautifully to several stylistic directions, for a contemporary cool palette choose a white metal setting such as platinum or 18 karat white gold with a fine halo of small brilliant cut white diamonds to increase perceived size and to create contrast that lifts the greenish blue tone. For a warmer and more distinctive look consider pairing the spinel with small yellow sapphire or citrine accents set in 18 karat yellow gold, the warm side stones will accentuate subtle green undertones and create a sophisticated color contrast. For a delicate everyday piece a four or six prong setting will expose the girdle and let light enter the pavilion for maximum brilliance, while a thin bezel in a low profile mount will offer extra protection for active wearers without hiding the oval shape. If you prefer a designer composition try matching this stone with rose sapphire accents or tiny mandarin garnet melee for a bicolor cluster with vintage flair. The dimensions of 6.33 x 4.57 x 3.07 mm make this spinel ideal as a center for a midsize ring or pendant, or as a matched focal in three stone settings combined with tapered baguette or trillion shaped side stones, a skilled bench jeweler can optimize facet and bezel choices to maintain optical performance.
