3.35 Ct. Blue Topaz from Ceylon (Sri Lanka)

This marquise shape blue topaz offered by The Natural Gemstone Company is a transparent 3.35 carat gem with precise dimensions of 14.69 x 7.01 x 4.68 mm, faceted in a mixed brilliant cut to balance sparkle and optical depth. The stone presents a medium color intensity in a clean sky blue hue that is typical of quality Ceylon material, and the polish has been evaluated as excellent, producing crisp facet reflections and lively scintillation. Clarity is graded as very slightly included with evaluation at eye level, which means the stone reads visually clean to most observers while retaining minor natural inclusions that do not detract from brilliance or structural integrity. The color has been achieved through irradiation, a common and stable enhancement for blue topaz, and this treatment is fully disclosed in accordance with best practice and the provenance information we provide for all items. Origin is identified as Ceylon, Sri Lanka, a respected source known for producing well crystallized topaz that cuts to attractive clarity and color profiles, and this provenance contributes to the gem s desirability for buyers who value traceable origins and consistent lapidary quality.

From a custom jewelry perspective this specimen is especially well suited to bespoke settings because of its size and classic marquise outline. The length to width ratio is approximately 2.1 to 1, creating an elongated, elegant silhouette that flatters rings, pendants, and drop earrings while visually elongating the finger or neck when set in solitaire or halo designs. The actual thickness of the stone is 4.68 mm, which compared to its average diameter of 10.85 mm gives a depth to average diameter ratio of 0.4314, a proportion that produces a pleasing face up spread and a lively play of light without excessive pavilion depth that can reduce apparent size. The mixed brilliant cut integrates a faceted crown arrangement with a partially brilliant pavilion to optimize return of white light and to produce flashes across the length of the marquise shape, making this topaz an excellent centerpiece for designs that benefit from directional sparkle. Because the gem is eye clean to most viewers and carries a medium color intensity, it pairs beautifully with both pavé accent stones and clean bezel work, offering versatility to designers and clients seeking either a contemporary minimal look or a more ornate, diamond framed composition.

Practically speaking this blue topaz is durable enough for everyday wear when it is set with appropriate protection for the delicate pointed ends of the marquise. We recommend a setting that secures the points with V prongs or a protective bezel at each tip, and consideration of a low to medium profile to reduce the risk of impact on the terminations. For metal choices white gold and platinum emphasize the cool blue tone, while warm metals such as rose gold provide a modern contrast that lifts the sky blue color. The irradiated treatment used to produce the color is stable under normal wear conditions, however prolonged exposure to very high heat or harsh chemicals should be avoided to preserve the hue and polish. For educated buyers assessing value this stone represents an attractive balance of carat weight, fine cutting, and eye level clarity, and its Sri Lankan origin and full disclosure of enhancement add provenance and transparency that collectors and custom jewelers appreciate.
