3.99 Ct. London Blue Topaz from Brazil

This transparent 3.99 carat London Blue Topaz from Brazil presents as an emerald cut measuring 10.11 x 8.14 x 5.45 mm, with a calculated depth of approximately 59.7 percent, and an emerald cut faceting design that emphasizes broad, parallel step facets and a large rectangular table. The step cut execution is precise, with well aligned facet junctions and beveled corners that both protect the stone from chipping and enhance the characteristic deep blue windows created by the pavilion steps. The intense color intensity is evenly distributed throughout the body of the gem, a result of controlled irradiation enhancement, and the excellent polish produces mirror like facet planes that yield crisp light return and deep internal contrast. Clarity is graded as very very slightly included evaluated at eye level, with inclusions that are minimal and non disruptive to the face up appearance, allowing the color saturation and step facet architecture to read with maximum presence in a single view.

Because of its substantial 3.99 carat weight, generous table and exceptional face up clarity, this London Blue Topaz is ideal for a statement piece that balances presence and refinement. The elongated emerald cut profile sits beautifully in a solitaire ring or a low profile bezel, and the stone also adapts well to halo and three stone constructions where the step cut geometry provides a clean, architectural interplay with accent stones. At The Natural Gemstone Company we emphasize the gemstone as the focal element, recommending settings that secure the beveled corners while allowing the table to dominate, so the intense blue and step facet reflections remain the visual priority. The irradiation enhancement responsible for the London Blue hue is standard within the trade, and the gem responds best to routine gem care such as warm soapy water and a soft brush. For customers seeking a bold, technically refined centerpiece, this specimen delivers exceptional optical clarity, robust color saturation, and cutting quality that reads clearly at size, making it a confident choice for a striking signature ring or pendant.
