1.52 Ct. Topaz from Ceylon (Sri Lanka)

This listing describes a single, transparent sky blue topaz presented by The Natural Gemstone Company, weighing 1.52 carats. The gem is fashioned in an emerald cut, which emphasizes clarity and linear facets, producing a clean, architectural table face. At 1.52 carats this topaz occupies a category that is both noticeable and practical for a wide range of fine jewelry applications, and the weight contributes directly to the stone's presence and perceived value. The description that follows focuses on the measurable attributes and the quality indicators that define this specimen, with particular attention to how the carat weight represents premium character in natural topaz.

The physical specifications are precise, and they reflect careful cutting and finishing. The stone measures 7.96 x 5.78 x 3.96 mm, a proportion that balances face up area with enough pavilion depth to yield appealing light return in an emerald cut. Clarity is graded as very very slightly included, evaluated at eye level, a designation that indicates minor internal characteristics that do not detract from visual performance when viewed without magnification. Color intensity is medium light, producing a soft sky blue hue that reads as natural and refined rather than vivid or saturated. The polish is excellent, contributing to crisp facet junctions and a mirror like table appearance. Enhancement is by irradiation, a stable and commonly used treatment to produce or enhance blue tones in topaz. Origin is Ceylon, Sri Lanka, a region with a long history of producing gemstones with pleasing color and clarity for the international market.

The carat weight of 1.52 has specific implications for both aesthetics and valuation. In gemstones, carat denotes weight rather than size, but for a given species and cut, weight correlates closely with face up dimensions and depth. For topaz, which has a relatively high specific gravity compared with some other common gem materials, a 1.52 carat emerald cut yields a significant face up size while maintaining elegant proportions. This weight allows the gem to assert a presence on the finger or pendant without requiring an oversized mounting, making it suitable for classic solitaire settings as well as for refined three stone and halo configurations. From a grading and pricing perspective, gems in the approximate 1.5 carat range often command a premium relative to smaller sizes, because larger clean stones of desirable color occur less frequently and are more sought after by connoisseurs and designers.

Assessment of quality encompasses more than weight alone, and this stone pairs its 1.52 carat mass with other attributes that justify a premium classification. The emerald cut maximizes the perception of clarity and color uniformity, allowing the medium light sky blue tone to display evenly across the table. Very very slightly included clarity at eye level means that minor inclusions are present, but they are subtle and do not interrupt the optical flow of the cut under typical viewing conditions. Excellent polish ensures that light interacts with the facets as intended, contributing to a crisp, elegant look that complements the gem weight. The irradiation treatment enhances the blue color in a way that is stable under normal wear, and the combination of origin, cut, and finish results in a stone that presents as refined and collectible.

Practical considerations for setting, wear, and documentation are straightforward. The 7.96 x 5.78 x 3.96 mm dimensions combined with a 1.52 carat weight make this topaz adaptable to a variety of mounting profiles, and the emerald cut lends itself to secure bezel and prong settings that protect the corners and preserve the stone over time. As with all colored stones, routine care involves avoiding harsh chemical exposure and sudden thermal shock, while standard cleaning with mild detergents and a soft brush will maintain the gem s brilliance. The provenance from Ceylon, Sri Lanka is noted to provide context for origin and supply chain, and The Natural Gemstone Company adheres to sourcing practices that emphasize transparency and traceability. This sky blue topaz, at 1.52 carats, represents a balance of measurable quality factors that together convey premium status within its species.
