This description places the essential facts first so an educated buyer can quickly assess the gem. The weight of 17.67 carats immediately positions this emerald in a rare size class, particularly for stones that retain transparency and vivid hue. The oval outline coupled with a cabochon finish offers a strong visual presence while maximizing the material retained from the rough, and the dimensions of 17.82 by 14.76 by 9.97 millimeters deliver a substantial face up area that reads well in both statement rings and pendant settings. The Natural Emerald Company provides full disclosure of enhancement as standard, and we emphasize origin as Colombian because provenance is a fundamental value driver for collectors and connoisseurs.

Understanding the grading terms helps place this stone within established market criteria, clarity slightly included evaluated at eye level means that natural internal features are visible to the unaided eye but do not dominate the gem or obscure its attractive color and transparency. Inclusions in emeralds are part of their fingerprint, and for many buyers they serve as confirmation of natural origin and geological authenticity. The vivid color intensity describes a strong, saturated green that is exactly the quality collectors prize most, where the balance of tone and saturation creates a lively, deep green without being too dark. Polish quality labeled excellent ensures that the cabochon dome presents a smooth reflective surface, enhancing luster and color delivery. Enhancement described as standard reflects the common and accepted practice of clarity improvement through treatments such as oiling or resin filling that are customary for natural emeralds, and such disclosure is a key part of ethical trade. Colombian origin further elevates the piece, because Colombian emeralds are historically sought after for their pure and vivid green tones, and top quality material from Colombia consistently commands premiums in the market.

For the buyer who evaluates gemstones with a technical eye, this emerald checks many boxes that indicate both aesthetic and investment appeal, large carat weight, vivid color, reasonable clarity, natural transparency, and established provenance are the primary components of long term desirability. The cabochon cut favors a strong chromatic display and can be ideal for designs that protect the stone, such as bezel settings or substantial prong frameworks, and it also lends itself to collectors who prefer classic museum style mounts. Care recommendations for a gem with standard enhancement include avoiding steam cleaning, ultrasonic cleaners, and strong chemicals, gentle cleaning with mild soap and warm water is appropriate, professional inspection and reapplication of filling materials over time may be advisable for preserving appearance and stability.
