0.63 Ct. Bluish Green Sapphire from Madagascar

This cushion shaped bluish green sapphire weighs 0.63 carat, and measures 5.54 x 4.62 x 2.59 mm, yielding an overall depth of approximately 51 percent. The cutting style is faceted, executed as a mixed brilliant cut that combines a brilliant style crown with pavilion faceting designed to maximize light return while retaining a classic cushion silhouette. The hue sits in the bluish green family with medium color intensity, the clarity grade is very slightly included evaluated at eye level, the polish is excellent, the stone is free of any enhancement, and the documented origin is Madagascar. These specifications result in a natural, untouched material that presents balanced tone and saturation, with inclusions that are minimal to the eye and positioned to preserve both transparency and structural integrity. The girdle is proportioned to allow secure setting options, and the facet junctions are cut to produce precise symmetry and crisp facet edges, hallmarks of skilled lapidary work and the quality standards upheld by The Natural Sapphire Company.

Optically the mixed brilliant approach enhances both scintillation and face up color, the brilliant style crown with its carefully graded crown height and table proportions disperses light into lively flashes, and the pavilion geometry is tuned to return that light through the table for strong brilliance. The medium intensity bluish green behaves well under varied lighting, appearing cooler and more blue under daylight and revealing greener notes under incandescent or warmer light sources, this dynamic color shift is an attractive quality for connoisseurs who value stones with responsive color. The very slightly included clarity grade at eye level indicates inclusions that do not interrupt the path of light significantly, thus preserving high transparency and allowing the pavilion facets to create lively contrast patterning. The excellent polish minimizes surface diffusion, ensuring that facet planes act as efficient mirrors to produce crisp scintillation and clean color saturation across the table.

For setting and design, the 5.54 x 4.62 mm dimensions and cushion outline lend themselves to a variety of custom executions, from a classic solitaire to more complex halo and multi stone arrangements. A four or six prong head that ties into a low to medium profile bezel can protect the slightly rounded corners while allowing the crown to present maximum table area. A bezel will emphasize color, while a fine prong setting will promote brilliance and allow more light to enter the pavilion. For a refined halo, use melee round brilliant diamonds with very small tables to complement the mixed brilliant cut, the round brilliants will echo the crown facet geometry and amplify scintillation. For a sophisticated three stone ring, tapered baguette step cut side stones provide a complementary contrast to the cushion mixed brilliant center, the linear facet arrangement of baguettes will emphasize center stone color and create a balanced visual transition along the band. Metal choice influences perceived color, white metals such as platinum or rhodium plated white gold will reinforce cool blue notes, while warm yellow gold will accentuate the green component of the bluish green hue, both approaches are valid depending on the design intention.

Pairing this sapphire with complementary gemstones allows layered color narratives and technical synergy, for high contrast and brilliance pair the sapphire with colorless round brilliant diamonds, their higher refractive index and dispersion will boost apparent brightness and make the sapphire face up appear richer in tone. For a tonal green ensemble, tsavorite garnets or demantoid garnets provide vivid green saturation and strong chroma that will deepen the green aspect without overwhelming the sapphire, select medium to strong saturation green stones to maintain balance. For subtle tonal variation choose mint tourmaline or pastel green sapphires, which will create a soft gradient and highlight the stone’s bluish undertones. If you prefer contrast through warmth, pair with yellow sapphires or cognac diamonds, these warm accents will cause the eye to register the sapphire as cooler and more blue, enhancing its bluish green identity. When combining cuts, use step cut side stones or baguettes to offset the mixed brilliant center, or use matched brilliants in a pavé halo to harmonize facet reflections. At The Natural Sapphire Company we advise prototyping settings with wax models or renderings to verify face up color and light performance under real world lighting, this ensures the final custom piece optimizes the cushion sapphire’s medium color intensity, excellent polish, and uncluttered eye level clarity, resulting in a piece that is technically sound and visually compelling.
