4.19 Ct. Rutilated Quartz from Ceylon (Sri Lanka)

One beautiful transparent 4.19 carat radiant shape bluish grey rutilated quartz measures 11.88 x 8.45 x 6.07 mm, the stone is cut in a radiant style combining trimmed corners and a faceted pavilion to enhance both transparency and internal patterning, evaluated as very slightly included at eye level the specimen displays an expressive network of fine rutile needles that traverse the body of the gem, the medium light color intensity preserves a cool bluish grey hue while allowing the needle inclusions to read distinctly against a clear background, polish is excellent and no enhancement has been applied, origin is Ceylon Sri Lanka, this offering is presented by The Natural Gemstone Company, its substantial 4.19 carat weight and balanced proportions make it suitable for a variety of fine jewelry applications where the rutilated pattern is intended to be a central feature.

Under natural daylight the gem presents its truest tonal balance, daylight emphasizes the bluish grey body color and produces crisp contrast between the transparent quartz and the darker rutile needles, the internal needle lattice scatters light along linear paths causing subtle internal shimmer and occasional metallic glints as light catches individual rutile strands, in direct sunlight those metallic glints intensify and the needles can read with greater definition, the stone can appear almost graphic when held to bright sun, in soft diffused daylight the overall effect is more uniform and textural, the bluish grey washes across the facets creating a calm silvery appearance where the rutile network contributes depth rather than strong contrast, warm incandescent lighting shifts the perceived color toward a softer grey with a faint warm undertone, this reduces the starkness of the needles and favors the gems transparency, cool white LED illumination tends to accentuate the silvery sheen of the rutiles and the crisp facet edges produced by the radiant cut, in low light the gem displays less color intensity but the rutile pattern remains visible as a delicate internal structure, movement and angle alter the balance between sparkle from the facets and metallic reflection from the rutile, the excellent polish and radiant faceting maximize light return while preserving the aesthetic of the inclusions, the result is a versatile stone that offers distinct visual personalities under varied lighting conditions, this quartz is untreated and stable, its appearance will depend on mounting style and exposure to light, mounting that allows light to pass through the pavilion will best highlight internal needles and transparency, photographs under multiple lighting conditions are available on request to illustrate the stone behavior in situ, for further technical information or viewing images The Natural Gemstone Company can provide additional details.
