1.13 Ct. Greenish Blue Sapphire from Ceylon (Sri Lanka)

This heart shaped greenish blue sapphire weighs 1.13 carat, and measures 6.09 by 7.01 by 3.70 millimeters, showing the careful proportionality that collectors and designers seek. The cutting style is faceted, executed as a mixed brilliant cut configured for a heart outline, and the cutter has balanced a well sized table with a moderate crown to maintain scintillation across the lobes and the cleft. At approximately 56.6 percent depth, the stone sits within an optimal range that supports strong light return while preserving face up color saturation. Clarity is graded slightly included at eye level, which means small natural inclusions are present but do not dominate the visual field, and the excellent polish enhances facet definition and surface luster. This sapphire is untreated with no enhancement, and its origin is Ceylon Sri Lanka, a source long respected for producing sapphires with lively hues and natural vibrancy, and this piece is presented by The Natural Sapphire Company.

Color characteristics of this sapphire lean toward a greenish blue with vivid intensity, which indicates strong saturation combined with a medium to medium dark tone that reads as lively and substantive under daylight and artificial lighting. The mixed brilliant faceting pattern helps to distribute color across the table and adjacent crown facets, reducing apparent color zoning and allowing pleochroic components to manifest as shifting proportions of blue and green when the stone is tilted. Because the sapphire is unenhanced, the color originates from its natural trace element chemistry and crystal lattice response, and the vivid rating speaks to a desirable balance of hue, tone, and saturation. Slight internal features act to scatter light and in some viewing angles contribute to a slightly velvety texture, yet the overall face up presentation remains transparent and vibrant, which is important for fine jewellery applications that rely on both color and clarity.

The workmanship of the mixed brilliant heart demonstrates deliberate facet geometry, with precise pavilion angles and carefully placed star and kite facets on the crown to maximize return and scintillation. The heart form requires attention to symmetry of the two lobes and to the definition of the cleft, and the cutter here achieved even lobes and a well proportioned cleft that reads clearly even at small scale. The girdle appears consistent and appropriate for conventional mounting techniques, supporting bezel and prong settings without introducing stress points. For protective considerations, a v shaped prong at the cleft and a tapered prong at the point are recommended to shield these vulnerable areas while maintaining light admission. Metals and finishes influence perceived color, and in this case 18 carat yellow gold will warm the greenish notes making the gem appear richer, while platinum or 18 carat white gold will preserve cooler blue components and enhance contrast, and a two tone approach can be used to balance warmth and coolness across the design.

When integrating this heart shaped sapphire into a custom piece, complementary gemstones can reinforce or offset the greenish blue identity depending on the design objective. For maximum brilliance and optical expansion, a tight halo of small round brilliant white diamonds calibrated to the face of the heart will amplify dispersion and increase perceived size, using clean diamonds with strong cut grades to preserve sparkle. For tonal harmony, light green or mint colored sapphires as melee flanking stones will echo the green component and create a soft graduated field of color. For a bolder approach, pairing this sapphire with teal tourmaline or paraiba inspired blue green tourmaline accent stones will create layered depth of color and a modern palette. Side stones in tapered baguette or tapered trillion shapes set with their broader ends toward the center will visually elongate a ring design, while asymmetric clusters that include small pink sapphires or warm champagne diamonds can introduce contrasting color accents that make the greenish blue pop. In all cases artisans should respect the untreated nature and Ceylon origin by choosing secure settings and rub over seats or bezel rails that protect the stone while maximizing light interaction and aesthetic balance.
