两份清单，不是一份

各月诞生石

本页的清单是美国的：1912年由全国珠宝商协会在堪萨斯城通过，此后在1952年、2002年和2016年改过三次。它是行业标准，而非传统。下表列出清单通过时的样子和今天的样子，并标出两者不同的月份。

A hand-coloured plate of two rock fragments studded with dark blood-red dodecahedral garnet crystals, one bedded in grey-green schist and one in rusty brown matrix, with two loose crimson crystals and two outline diagrams of the twelve-sided form.Garnet一月A hand-coloured plate of two quartz specimens: above, a crust of small violet amethyst points on a pale cream nodule; below, a larger broken mass crowded with faintly purple, sharply pyramidal quartz crystals over its whole upper surface.Amethyst二月A hand-coloured plate of a large broken beryl crystal, its vertical faces finely striated and shading from sea-green through milky white to buff, with a smaller weathered prism beside it and an outline diagram of the six-sided crystal below.Aquamarine三月A hand-coloured plate of seven diamonds. Five are drawn as fine outline diagrams showing the facet patterns of brilliant, rose and table cuts; two are fully coloured deep blue-black brilliants, one seen face-on and one in profile.Diamond四月A hand-coloured engraving of two emerald specimens: a slender deep-green hexagonal prism lying across a pale grey calcite matrix, and below it a large blocky green crystal seated in white rock speckled with small green grains.Emerald五月A single valve of the pearl oyster shown against a black ground inside an ornamental printed border: the shell is creamy white with concentric growth lines and a notched hinge, and one small round pearl sits attached to the nacre near its right edge.Pearl六月A hand-coloured engraving of nineteen numbered corundum crystals in rows, most of them rose and crimson ruby, barrel-shaped or six-sided; also an orange-brown prism, a pale grey star-stone, and at lower right one large deep blue sapphire crystal.Ruby七月A chromolithograph headed Epidote, Garnet and Olivine. Low on the plate a pale yellow-green olivine crystal with a flat terminated top, and at the right the same stone cut as a vivid grass-green oval, among dark red garnets and green epidote.Peridot八月A hand-coloured plate headed Colored Stones. At top left a deep blue cushion-cut sapphire; at top centre a large rough blue-grey sapphire showing a white six-rayed star; below them ruby, amethyst, yellow and orange stones, pale green cabochons and banded agate slices.Sapphire九月A hand-coloured engraving of a single opal nodule set alone on the page: an irregular water-worn lump whose broken face is milky blue-green and cream with faint yellow patches, edged along the underside by a rough dark brown weathered crust.Opal十月A chromolithograph of topaz: a pale blue crystal seated in buff matrix, a tall deep golden-orange striated prism, a lemon-yellow crystal on a druse of white crystals, a small rose-red prism, and cut stones in pale blue, amber, yellow and pink.Topaz十一月A hand-coloured engraving of three turquoise specimens one above another: a pale blue-green crust broken into rounded patches within a dark green rind, a knobbly botryoidal mass, and a flat splintery slab of clear sky-blue turquoise seen edge-on.Turquoise十二月
