18K Gold Tsavorite Diamonds Ring/pendant (With GUILD Cert) - Kijani green

In the world of high-end luxury jewelry that stays at the forefront of trends, tsavorite is never absent. Combining the color of emeralds with the brilliance of diamonds, tsavorite has become one of the gemstones most favored by high-end jewelry designers in recent years.

Tsavorite is the rarest garnet in the garnet family, with its color primarily derived from trace amounts of vanadium and chromium elements. Its high refractive index, exceptional brilliance, and remarkable clarity—combined with its completely natural state, free from any human enhancement—make tsavorite a rare example of innate beauty in the gemstone world.

The global production of tsavorite is extremely limited, and it has so far only been found in Kenya and Tanzania. Tsavorite forms in rock fissures, making its extraction exceedingly difficult. Individual stones over 1 to 2 carats are already quite rare, and those over 5 carats with rich color are even more exceptional. In terms of rarity, tsavorite is 1,000 times rarer than emerald.

Compared to emeralds, the value of tsavorite is still underestimated. However, with declining production and its unique combination of beauty, rarity, and durability, tsavorite is bound to see a rise in value. Whether judged by its frequent appearances at auction houses at high prices or by the growing interest from major jewelry brands, tsavorite is a colored gemstone with strong potential for continued appreciation.

In GUILD Gem Laboratory's color grading system for tsavorite, the evaluation criteria for the "Kijani Green" color grade are based on three key aspects: tone, saturation, and hue. Only tsavorites with sufficiently high saturation and an optimal tone can be awarded the "Kijani Green" grade.

While "Kijani Green" may sound like merely a color grade, it actually imposes certain thresholds on other aspects of the gemstone as well. First, the tsavorite must be untreated—free from any filling, surface coating, dyeing, or other color alteration processes. Second, it must not exhibit any significant quality issues, such as distinct color zoning or visible dark inclusions. In addition, there are specific standards for cut quality: stones with an overly shallow cut (windowing) or excessively thick pavilions do not qualify.
