1.23 Ct.Tw.Total Carat Weight Topaz Pair from Ceylon (Sri Lanka)

This pair of blue topaz gemstones presents a precise balance of weight and dimensions, a key indicator of premium lapidary quality. The stones weigh 0.59 carats and 0.64 carats respectively, weights that reflect careful yield management during cutting, and that deliver strong face up presence without compromising table size or pavilion depth. The first stone measures 6.04 x 4.05 x 2.59 mm, the second measures 6.02 x 3.99 x 2.41 mm, producing calculated depth proportions of approximately fifty one percent and forty eight percent respectively. These depth proportions are consistent with an emerald cut strategy that favors controlled light return over flamboyant scintillation, optimizing the perceived color and transparency typical of higher grade jewelry topaz. Given topaz specific gravity near 3.53, these dimensions align tightly with the stated carat weights, confirming accurate cutting and minimal material loss, characteristics collectors and designers associate with premium gemstones from The Natural Gemstone Company.

Both stones are executed in the emerald cut, employing classic step cut geometry with broad rectangular tables and well defined step facets along the crown and pavilion. The step faceting yields a hall of mirrors effect that emphasizes clarity and color, presenting blue hue in broad flashes rather than dispersed sparkle. Facet junctions are crisp, facet planes are planar, and symmetry maintains parallel alignment of the steps, all contributing to an excellent polish grade. Clarity has been evaluated as very slightly included at eye level, a trade term indicating inclusions are minor, typically pinpoint or faint feather characteristics, that do not disrupt overall transparency or the integrity of the step facet reflections. The medium light color intensity reported for both stones provides a well balanced hue saturation and tone, avoiding both the washed out appearance of very light stones and the overly dark table seen in deep tones, which is particularly desirable in emerald cut blue topaz when paired in matched sets for fine jewelry.

These blue topaz specimens have undergone controlled irradiation enhancement, a standard and fully disclosed treatment used to induce and stabilize blue coloration in topaz sourced from natural material. The irradiation process utilized is consistent with industry practice, producing durable color that performs reliably under normal wear and standard jewelry maintenance, while preserving the inherent clarity and crystalline luster of the topaz. Origin information traces the material to Ceylon Sri Lanka, a provenance that reflects a long history of skilled cutting and careful material selection. The combination of origin, enhancement disclosure, tight dimensional control, and matched weights underscores the pair as a premium offering, suitable for use in refined matched earring pairs or complementary set components where symmetry and color consistency are essential.

When specifying these stones into a design, their carat weights of 0.59 carats and 0.64 carats should be considered in relation to mounting bezel and prong geometry, as the emerald cut profile presents a larger visual table for a given carat weight compared with more deep cut styles. The measured depth proportions support secure setting without excessive claw extension, and the very slightly included clarity grade allows for open point prong or four prong settings that expose the table for maximum visual impact. The excellent polish promotes optimal light transmission and ensures that metal reflections are clean and unbroken, a critical factor when pairing with white metals or platinum to enhance the cool blue tone. For clients seeking a technically refined pair that combines precise carat representation, verified enhancement disclosure, and Sri Lankan provenance, The Natural Gemstone Company presents these matched emerald cut blue topaz stones as a premium choice for custom jewelry applications.
