Burma (Myanmar) and Guatemala are the principal sources of modern gem jadeitite, and Canada of modern lapidary nephrite.

缅甸和拉是现代翡翠的主要，而加拿大是现代宝的主要。

When cutting most pleochroic gemstones (Iolite, Tanzanite, Kunzite etc.), lapidaries typically try to minimize the pleochroism and maximize the single most prominent color.

在切割大多数的多向色性类宝时（如堇青、坦桑宝、辉等），通常宝匠会尽量缩小多向色性并最大化将某一主色凸显出来。
