About Ema egg
Formula:
SiO2
Name:
From the Portuguese ovo de ema, "egg of the ema", in reference to a fancied resemblance to the egg of the ema (greater rhea, or Brazilian ostrich, Rhea americana).
Trade name for a river-tumbled pebble of transparent quartz with a frosted exterior resembling an egg shell, originally collected from rivers in Brazil, with one side sawn flat and polished as a window to view the interior. Pebbles of quartz and other minerals also are tumbled mechanically to simulate the natural article for sale under this name. Discussed on the Mindat messageboard, https://www.mindat.org/mesg-455101.html.
