2.47 Ct. Cabochon Topaz from Ceylon (Sri Lanka)

This listing from The Natural Gemstone Company presents a beautifully translucent, oval shape white topaz weighing 2.47 carats, with exact dimensions of 10.00 by 8.01 by 5.67 millimeters, a cabochon cut, eye clean clarity as evaluated at eye level, colorless color intensity, and an excellent polish. The piece originates from Ceylon Sri Lanka, and has been enhanced by irradiation, a commonly used and stable treatment that can improve or stabilize color in topaz, disclosed here for full transparency. The gem displays a clean, near colorless body tone that is highly desirable to collectors and connoisseurs seeking a versatile, refined stone that can function equally well as a design focal point or as an elegant accent. In addition to the topaz description, the listing includes reference to White Opal as an opal type for customers seeking complementary white gemstones, and this comparative framing helps educated buyers understand how this white topaz sits alongside other light colored materials in terms of translucency, play of light, and use in fine jewelry.

The cabochon cut on this oval topaz is executed to emphasize translucency and surface luster, and the overall cutting proportions maintain pleasing symmetry across the table and girdle. Cabochons are traditionally chosen to showcase a gem s inner glow and surface reflection rather than the faceted brilliance associated with brilliant cuts, and in this instance the cabochon shaping enhances the stone s soft brilliance and internal light diffusion, creating a luminous effect that reads beautifully in bezel settings, rings, and pendants. The excellent polish reported on this piece produces clean light return and a satiny mirror finish on the dome, which contributes to a refined appearance under both natural and artificial light. For collectors who value exceptional cutting as a determinant of aesthetic and resale value, the controlled curvature, uniform dome height, and absence of surface pits or polish lines indicate careful lapidary work that elevates the piece into the level of a collection centerpiece.

Clarity is a principal factor in value for transparent gemstones, and this topaz earns an eye clean grade as evaluated at normal viewing distance, which means that inclusions are minimal to absent to the unaided eye when the stone is observed under typical conditions. Eye clean clarity in topaz allows for maximal light transmission, which in turn enhances perceived size and brilliance, and the reported translucency combined with a colorless body results in excellent apparent brightness. From a gemological perspective, eye clean material is attractive because it requires less of a price concession compared with material that contains obvious clouds or crystals, and it is especially prized in larger sizes where inclusions can have a disproportionate visual impact. The irradiation enhancement applied to this stone is a recognized practice for adjusting or stabilizing color in topaz, and when performed and disclosed properly, it does not compromise the structural integrity of the gem, nor does it adversely affect wearability. For buyers who require third party verification, we recommend sending the gem to a reputable laboratory for a treatment and origin report, which will document the irradiation and confirm clarity and color attributes.

The provenance of this topaz from Ceylon Sri Lanka is notable, as Sri Lanka has a long history of producing high quality, clean gemstones with strong trade and lapidary infrastructure, which often results in well cut, well finished material that is traceable through established supply channels. The geological environment of Sri Lanka favors the formation of high clarity topaz in pegmatites and gem gravels, and gem material from this source is commonly appreciated for its clarity and stable color response to standard treatments. At The Natural Gemstone Company we prioritize ethical sourcing and transparent disclosure, and we can provide additional provenance detail upon request, including export documents and the history of the stone within our supply chain when available. Care for a cabochon cut topaz is straightforward, we recommend avoiding prolonged exposure to high heat or harsh chemicals, storing the gem separately to prevent abrasion, and routine cleaning with warm soapy water and a soft brush or ultrasonic cleaning when appropriate for the setting.

For the educated buyer considering placement in a collection or a bespoke piece, this 2.47 carat oval white topaz represents a practical blend of visual appeal, lapidary quality, and documented treatment history, making it an excellent choice for display, investment, or daily wear. When paired with White Opal or other light toned materials, the colorless topaz offers neutral contrast and a stable, brilliant presence that complements opal s iridescence without competing for attention. Suggested settings include a low bezel to protect the cabochon dome, or a halo design to amplify perceived size while securing the stone for everyday wear. The exact measurements of 10.00 by 8.01 by 5.67 millimeters make this gem suitable for center stone applications that require a balance of presence and wearability.
