1.61 Ct. Yellow Sapphire from Madagascar

This transparent yellow sapphire weighs 1.61 carat and presents a round shape with precise dimensions of 7.00 x 7.08 x 4.25 mm. The gem exhibits an intense color intensity that is evenly distributed across the table and crown, and it has been heat treated to stabilize and deepen the hue. Evaluated at eye level, the clarity is slightly included, which means small internal features are present but do not materially compromise the stone s overall transparency or its visual presence. The cut is a mixed brilliant, and the polish is excellent, producing a clean surface finish that supports strong light return. At The Natural Sapphire Company we document both the physical measurements and the enhancements in order to provide complete and transparent information about this specimen.

The mixed brilliant cut combines a brilliant facet arrangement on the crown with a step influenced pavilion, and this hybrid geometry is purposeful in balancing brilliance, fire, and color saturation. The crown facets are arranged to maximize forward scattering of light, while the pavilion facets are configured to control recirculation of light within the stone, encouraging return through the table and crown. With a depth of 4.25 mm against an average diameter of approximately 7.04 mm the depth percent is about 60.4 percent, a proportion that assists in concentrating the yellow tone without sacrificing lively scintillation. The result is a dynamic interplay between flashes of white light and subtle spectral dispersion, where the mixed facet geometry enhances both the stone s overall brightness and its colored character.

Clarity and polish work together with the cut to determine the perceived purity of light transmission, and in this sapphire the slightly included clarity presents as fine needle like or pinpoint features that remain unobtrusive at normal viewing distances. These internal features can in some cases contribute to a softening of direct reflections, adding a delicate texture to the gem s scintillation rather than introducing distracting cloudiness. The excellent polish eliminates surface diffusion that would otherwise scatter light and reduce contrast, so facet junctions appear crisp and reflective. The heat treatment applied to this stone is an established, stable enhancement that intensifies the yellow hue by modifying trace element distribution and improving visual uniformity, while retaining the gem s structural integrity and refractive behavior.

From a practical perspective the combination of 1.61 carat weight, round outline, and the mixed brilliant execution makes this sapphire a versatile choice for a variety of jewelry settings. The balance between depth and diameter yields a gem that mounts with a pleasing table presence and sustained color under both natural and artificial lighting. Slight inclusions and the heat treatment are fully noted for valuing and care considerations, and Madagascar origin provides geological context for the trace element profile responsible for the yellow coloration. When specifying this stone for a design or setting, attention to bezel height and pavilion clearance will preserve optimal light performance, and routine cleaning will maintain the excellent polish and visual dynamics. The Natural Sapphire Company provides this information to assist in informed selection and to ensure the gem s documented attributes are clear and verifiable.
