Garnets. Pyrope or magnesia iron and alumina garnet, though, 

 often found in serpentine, is in Scotland only recorded from basalt. 

 It occurs to the east of Elie, in Fife, and is known as the Elie ruby. 

 The common garnet, or iron alumina garnet, is characteristic of 

 micaceous gneiss and mica slate, especially at Killiecrankie, where 

 garnets are of the size of bullets, and embedded in a paste of mica. 

 The almandite is found in the micaceous gneiss of Sutherland ; and 

 the precious manganese garnet occurs in granitic belts in micaceous 

 gneiss near Strathpeffer in Ross-shire.
