A natural 1.86 carat tsavorite garnet in a rectangular cushion cut, completely untreated. Tsavorite is the most brilliant green gemstone — a calcium aluminum silicate colored by vanadium and chromium, producing vivid jewel-tone greens that rival or surpass the finest emerald in color intensity. The rectangular cushion cut gives this stone a modern, elongated footprint with the warmth of cushion faceting — a distinctive format for a genuinely rare green gem. At 1.86 carats untreated, this sits well above the typical 1-carat commercial range for tsavorite.

Why Choose this 1.86 ct Rectangular Cushion Tsavorite Garnet?

Tsavorite above 1.5 carats in a rectangular cushion format is uncommon — most tsavorite is cut oval or cushion (round-ish), and the elongated rectangular cushion requires larger rough crystal with sufficient color saturation across the entire length. At 1.86 carats, this stone has the face-up surface for a commanding green center stone, and the untreated status confirms nothing was done to enhance the color.

Key Benefits of this Natural Tsavorite Garnet

• Completely Untreated
  Tsavorite never requires treatment — this stone is natural exactly as cut from the rough.
• Rectangular Cushion Distinction
  Elongated modern format in vivid green — more architectural than square cushion or oval equivalents.
• Above-1.5-Carat Size
  Tsavorite above 1.5 carats is meaningfully rarer than sub-1-carat material at equivalent quality.
• Vivid Green — Superior to Emerald
  Same green palette as fine emerald; eye-clean, untreated, more durable for daily wear.
• Durable Emerald Alternative
  7–7.5 on the Mohs scale — significantly more robust than emerald for ring use.
