Tsavorite

Carat weight is a critical factor. While small tsavorites are relatively available, fine stones above 2–3 carats are rare, and gems over 5 carats in top color and clarity are exceptional and highly valued. Prices per carat increase steeply with size for high-quality material.

Color is the primary value driver. The most desirable tsavorite exhibits a vivid, evenly distributed medium to medium-deep green, sometimes with a slight bluish or yellowish modifier but without being too dark or too light. Stones that are overly pale, strongly yellowish or too dark trade at lower price levels.

Tsavorite is often relatively clean, and faceted stones are expected to be eye-clean or nearly so. In larger stones, minor inclusions may be tolerated, but heavy inclusions or fractures that reduce transparency and brilliance significantly lower value.

Good cutting maximizes tsavorite's high refractive index and brilliance while managing depth of color. Well-proportioned mixed cuts in ovals, cushions and rounds are common. Poorly cut stones may appear overly dark or have windowed centers that diminish color impact.

Tsavorite deposits are primarily found in East Africa, especially in Kenya and Tanzania, often in geologically challenging and limited zones. Mining is largely artisanal or small-scale, and production of fine-quality material is restricted compared with many mainstream gems.

Demand is strong among high-end jewelers and collectors who appreciate tsavorite as a more durable, often untreated alternative to emerald. Its bright, lively green and relative scarcity have led to increasing prominence in luxury jewelry.
