lapidary GRE

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

缅甸和危地马拉是现代翡翠的主要产地，而加拿大是现代的主要产地。

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时（如堇青、坦桑、紫锂辉等），匠会尽量缩小多向色性并最大化地将某一主色凸显出来。
