          Mali Garnet Value, Price, and Jewelry Information

          Cushion-cut Mali garnet, 0.95 cts, 6.7 x 5.1 x 3.4 mm, Mali. ? ARK Rare Gems. Used with permission.

          Mali Garnet

          One of the rarer varieties in the garnet group, Mali garnet is a blend of grossular and andradite. Discovered in 1994 in Mali (still its only known source), this gemstone has great brilliance and a high dispersion. Its colors range from almost tsavorite green to yellow-green, yellow, gold, and brown.

          Mali Garnet Value

          Without question, the high-value range for Mali garnets is reserved for those with extremely rare chrome-green color. In general, green, yellow, and green-yellow stones command higher prices than brownish stones. As with any gem, carat, clarity, and cut affect the value dramatically, but dispersion is a special?value factor for Mali garnets.

          In the year following the discovery of Mali garnets, a great deal of material was produced, and the popularity of this pretty stone soared. Although prices were initially very high, they soon dropped. Recent years have seen far smaller amounts produced. This has resulted in a price increase. Since large rough is rare in this variety, price per carat rises dramatically with size.

          Gemological study has established that Mali garnets have a composition somewhere between grossular (calcium aluminum silicate) and andradite (calcium iron silicate). This blend is sometimes called “grandite.”

          Mali garnets are predominantly grossular, but the variable admixture of andradite changes its characteristics in at least one important way. While this hybrid seems to favor its grossular parent in terms of refractive index (1.77 in most specimens) and hardness, its superb dispersion?comes from its andradite heritage.

          Some rare Mali garnets may show a color change from grayish green in fluorescent light to brown in incandescent light. Nevertheless, most color change garnets are a pyropespessartite blend.

          Mined from alluvial deposits, most Mali garnet rough typically shows rounded, waterworn shapes.

          Faceted stones with a light body color will show off their brilliance?spectacularly.
