27.49 Ct. Topaz from Brazil

This transparent yellowish green topaz weighs 27.49 carats, presenting a generous oval silhouette that measures 20.18 x 16.51 x 13.18 millimeter, and it offers an immediate sense of scale and presence that is uncommon in single stones of this hue. The gem has been fashioned to a mixed brilliant cut, which combines step and brilliant facet elements to balance depth of color with lively internal reflection, producing a stable, intense body color that reads as yellowish green when viewed against neutral backgrounds. Clarity has been assessed as eye clean when examined at normal viewing distance and under typical lighting conditions, permitting unobstructed appreciation of the color and cut plane geometry. The polish is excellent, ensuring crisp facet junctions and minimal surface disturbance, which in turn supports strong light return and an overall clean visual presentation that maintains the stone as the principal visual focus in a custom design crafted by The Natural Gemstone Company.

Technically the mixed brilliant cut here emphasizes a broad faceted pavilion with a brilliant style crown, and that configuration enhances scintillation while preserving color saturation across the table and crown regions. The depth at 13.18 millimeter supports robust internal reflection, and the oval proportions lend the gem to elongated settings that accentuate finger length in rings or a refined pendant profile. The origin is Brazil, and the specimen has been heat treated as a standard and stable enhancement to intensify and uniformize color, a treatment that is permanent under normal wear and care. The stone sits comfortably within the wearability expectations for topaz, which has durability suitable for many types of jewelry when set with attention to the long axis of the oval and to the protection of the girdle and corners. The weight and dimensions make this topaz a statement center stone, yet its transparency and excellent polish allow it to function equally well in a restrained, classically proportioned setting or in a more modern open gallery mount, depending on the intended silhouette and practical considerations of the wearer.

When considering complementary gems to accompany this yellowish green topaz in a custom piece, color theory and contrast will inform material selection, and this topaz pairs most effectively with gemstones that either provide neutral contrast or that highlight the green component of the color. White diamonds are a straightforward and enduring companion, offering neutral brilliance that frames the topaz without competing with its color, and small melee diamonds in a halo or on the shoulders will increase perceived brightness and lend a contemporary jewelry vocabulary to the composition. For color emphasis, faceted green stones such as tsavorite garnet or chrome tourmaline will harmonize with the topaz and produce a coordinated green palette, while teal or aqua sapphires will create a cooler contrast that accentuates the yellow undertone. For a richer, warmer expression, cognac or champagne diamonds will add a subtle warm counterpoint that plays against the yellow component and produces a complex, layered appearance. Gem sizes for accent stones will typically range from one to four millimeter for pavé and halo work, and from three to six millimeter for side stones in three stone or cluster arrangements, so that the center stone remains visually dominant while the accents provide proportional support.

In terms of metal choices and mounting styles, eighteen karat yellow gold or rose gold will enhance the warm aspect of the yellowish green color and generate a cohesive, vintage inspired appearance, while platinum or white gold will emphasize color contrast and clarity, useful when the objective is a crisp, modern presentation. A low to medium gallery with protective prongs that follow the long axis of the oval will offer balance between security and light performance, and a bezel with a fine milled edge will provide maximum protection while slightly muting brilliance. Design options that work particularly well for this size include a classic halo, where a single row of diamonds or colored gemstones follows the oval outline and increases apparent size, a three stone composition with matching or contrasting side stones to accentuate length, and a pendant with an articulated bail to allow light to pass through the crown and enhance internal reflections. The Natural Gemstone Company can provide precise matching recommendations for carat and millimeter proportions for any of these configurations, ensuring that the physical attributes and visual behavior of this Brazilian topaz are optimized in the finished custom piece.
