Comment: This is a newcomer to the market. Clean, especially for such a size, radiant color between green and yellow with good luster. Well cut, no window. Silimanite is 7.5 on the hardness scale so it will do fine in jewelry as long as you it him off for bar fights. We do not know what other color types this new mine will produce but this is good start. Majestic ringstone for under $150/carat. As all new natural gemstones this variety is only to go up in price when it goes into the ready-made jewelry market and demand surges.
