| Na3(Fe,Mg)4(Fe,Al)Si8O22(OH)2 - Brilliant black prismatic crystals up to 3". Also found as inclusions within smoky quartz. | |
| (K,Na)3(fe,Mn)7Ti2Si8O24(O,OH)7 - Bronze micaceous bladed aggregates with metallic luster are found within some miarolitic cavities. Some smoky quartz crystals contain brilliant thin metallic-lustered red blades of astrophyllite. | |
| CeCO3(OH,F) - mm-scale orange prismatic hexagonal crystals. | |
| KAlSi3O8 - Miarolitic cavities lined with opaque white crystals to 1/2". | |
| (Na,Ca)3(Y,Ce)12Si6B2O27F14 - Rare small mm-scale tan to peach colored crystls in miarolitic cavities. | |
| SiO2 - Milky to smoky crystals line pockets. Crystals are up to nearly a foot in length and vary in quality. Some large gemmy quartz is smoky-amethyst. Inclusions of arfvedsonite, astrophyllite, or other species are common. | |
| Na2Fe+32Fe+23(Si8O22)(OH)2 - Acicular opaque dark blue-green cystals. Some riebeckite is absestiform. | |
| FeCO3 - mm-scale rhombohedra in miarolitic cavities. | |
| NaLiZrSi6O15 - white to gemmy pink crystals to 1". | |
| ZrSiO4 - Individual crystals to < 1/2" are found within some cavities. Specimens are brown, lusterous, and exhibit tetragonal prism faces. |
