4 Estaciones
Lisbet Newton • April 15, 2026
Chivor is among the oldest and most celebrated emerald mines in the world - worked since pre-Columbian times, prized by Spanish conquistadors, and still yielding some of Colombia's finest stones.
In the world of Colombian emeralds, untreated stones are the exception, not the rule. Nearly every natural emerald on the market has received some degree of oil or resin treatment to enhance its appearance. The four stones that make up 4 Estaciones have not. What you see is entirely what the earth produced.
The Chivor mine sits in the Eastern Andes of Colombia, distinct from Muzo and Gachalá in both geography and character. Chivor emeralds are recognized for their cool, slightly bluish-green tone, a color that reads as pure and refined under any light. Each of the four stones in this collection carries that unmistakable Chivor signature.
At F1, the highest clarity classification in the Colombian grading system, these emeralds require no enhancement to present beautifully. Their natural clarity is the story. The square cut was chosen to honor that: its clean lines and open table facet make no attempt to hide anything, because there is nothing to hide.

At approximately 0.65 carats each, the four stones are well-matched in size, a quality that makes them particularly suited for use as a set. A jeweler could mount them as a quartet in a statement piece, use them individually across a suite of jewelry, or present them as a collector's set. The possibilities are as varied as the seasons themselves.
Treatment disclosure: These stones carry no treatment of any kind, no oil, no resin, no enhancement. This is rare in the emerald trade and represents a significant distinction in both value and collectibility. F1 clarity further confirms that these stones needed no intervention to shine.
The pear — or drop — cut is one of the most flattering shapes in fine jewelry. Elongating, graceful, and luminous, it was designed to be worn. Not every great emerald is meant to sit behind glass. This 1-carat pear-cut stone from the Gachalá mining district of Colombia is the kind of gem that finds its purpose in motion — suspended from a pendant, set in a solitaire ring, or anchoring a bracelet where it catches the light with every gesture. The pear shape, also known as the teardrop cut, combines the tapered point of a marquise with the rounded base of an oval. The result is a silhouette that appears larger than its carat weight suggests, an important quality in a one-carat stone. When set in a pendant or drop earring, the shape moves naturally with the body; in a ring, it elongates the finger and draws the eye. This stone carries the unmistakable identity of its Gachalá origin, the warm, slightly bluish-green tone that collectors associate with Colombia's eastern mining belt. The color is genuine and unaltered, a product of the geological conditions unique to that region. Graded at F3 Major, this emerald has received more significant enhancement than a lightly treated stone, a characteristic that is fully disclosed and reflected in its accessible price point. For a jeweler or collector seeking authentic Colombian origin in a versatile, wearable size, this represents strong value.
Sourced from the legendary mining district of Gachalá in the Eastern Andes of Colombia, this 2.77-carat cushion-cut emerald represents the kind of stone that seasoned collectors recognize on sight — substantial in size, vibrant in color, and remarkably clean for a natural Colombian gem. The cushion cut was chosen deliberately. Its softly rounded corners and larger facets allow maximum light to enter and reflect through the stone's interior, showcasing both its depth of color and the natural clarity that sets this piece apart. The result is a gem that moves with light — catching and releasing it in a way that feels alive. At the F2 clarity grade, this emerald falls well within the accepted standard for natural Colombian stones of this caliber. It is considered part of their character, referred to in the trade as jardin (garden). An F2 designation indicates that the inclusions present are minor and do not compromise the stone's overall beauty or structural integrity. What distinguishes this particular stone is the balance it achieves across all four key attributes: size, brilliance, color saturation, and clarity. Gems that excel in all four simultaneously, especially from a mine as storied as Gachalá, are increasingly rare. Colombian Emerald Portfolio · Gachalá Origin · Natural Gemstone Treatment disclosure: This stone has received oil and permanent resin treatment, a universally accepted and standard industry practice for natural emeralds. The treatment enhances the gem's visual clarity without altering its natural color or origin. Full disclosure is provided in keeping with international gem trade standards.
