A micromount of good quality. First, under sunlight the Allactite crystals are a faint tan with hints of pink. It's the same color under LED and quartz halogen lights. Fluorescent light yields a greyish color. Under halogen, the lights I use for photography, they are a beautiful rose-pink. So if you buy this specimen, use halogen lights to view it! 

These are excellent, complex, tabular crystals to less than 0.75mm. The dark red crystals on the Alaactite are the Hematolite. Note - Ex - Neal Yedlin micromount. Overall the specimen is 1.5 x 0.8cm.
