1.67 Ct. Emerald from Colombia

This listing presents a transparent 1.67 carat asscher octagon shape green emerald, with precise dimensions of 7.47 x 7.21 x 5.04 mm, originating from Colombia. The cutting style is faceted, executed in a classic asscher cut which produces an octagonal outline through carefully truncated corners. The clarity grade is slightly included, evaluated at eye level, the color is of vivid intensity, and the polish is excellent. Enhancement conforms to standard industry practice, which preserves the stone integrity while improving apparent clarity. At The Natural Emerald Company we emphasize measurable characteristics and provenance, and this emerald is a textbook example of Colombian material in both optical response and internal character.

The asscher cut used here is a step cutting tradition that relies on concentric rectangular facets on the crown and pavilion to create a hall of mirrors effect, sacrificing scintillation for depth and recurring flashes of tone. The faceter has maintained strict symmetry between length and width, producing crisp corner truncations and parallel facet junctions that align the pavilion steps beneath the table. With a depth of approximately 69 percent relative to the average of length and width, the proportions favor color saturation rather than excessive dispersion, which is appropriate for a vivid green. The excellent polish enhances light transmission, and the precision of facet junctions reduces light leakage, so the asscher architecture serves to display a uniform body color across the table while allowing the subtle internal features to contribute to character.

What makes this specimen unmistakable are the inclusions and growth features that act as a fingerprint, tying the stone to Colombian crystallography. You will find three phase inclusions comprised of a gas bubble, liquid film, and a tiny crystalline seed, which are diagnostic when combined with fine two dimensional growth zoning and delicate tension fissures. These features are distributed in a manner that reads as a micro topography, a jardin of interconnected platelets and feather like inclusions that do not dominate the table but lend depth when viewed face up. The slightly included clarity grade evaluated at eye level indicates these features are visible to a trained viewer without magnification in certain orientations, yet they remain discrete enough to preserve transparency and color purity. Standard enhancement fills minute fissures, reducing internal contrast and improving visual clarity, while leaving the characteristic inclusions intact so the stone retains its natural signature.

From a setting and care perspective this emerald is ideal for a fine jewel where the asscher geometry can be displayed in a protective mount. The step cut reads larger per carat than many brilliant cuts due to the broad table and the even distribution of color, making the 1.67 carat weight feel generous to the eye. For daily wear we recommend a bezel or partial bezel setting that protects the corners and minimizes exposure of the internal fissures to mechanical stress. Cleaning should be undertaken with warm water, mild soap, and a soft brush, avoiding ultrasonic baths that can stress filled fissures. As specialists, The Natural Emerald Company will provide detailed images, facet maps, and grading notes on request, and we can advise on setting styles that both protect and accentuate the distinctive Colombian character of this asscher emerald.
