MONTANA SAPPHIRE GRAVEL
Bringing you unwashed sapphire gravel from 3 Montana Sapphire deposits!
The sapphire material we offer is still in the virgin state and is brought in from
private claims on the El Dorado Bar of the Missouri River, Helena Area, from
Melee Gulch in the Sapphire Mountains of Philipsburg and we also carry Yogo
Dike material from the Roberts mine near Judith Basin, Utica, Montana.
The sapphires found in the El
Dorado Bar of the Missouri River
range from 1 to 12 carats, with the
largest to date being 34.7carats!
Sapphires from this deposit tend to
run larger than Rock Creek gems
but are tough to spot due to their
rough shape and muted colors
amongst the river gravel. El Dorado
sapphires come in a wide range of
colors, with several color-shift
stones being produced. You may
find an occasional ruby, garnet, and/or hematite specimen. Often the hematite
has replaced various seeds, nuts even clam shells and give you a fossilized
impression that's quite interesting and fun to add to your collection. This
material may also contain small flakes of gold, fossils or petrified wood.
Virgin Rock Creek sapphire material from the Mountains of Philipsburg
provides another flavor or sapphire mining. This deposit is rich in clay, making
it a little tougher to wash clean but the sapphires have a more polished look
due to weathering, making them easier to spot. They come in every color of the
rainbow but tend to be light blues and greens, resembling sea-glass or old coke
bottles.
Bags of sapphire gravel are available in our store to screen on premise in our
outside screening area. If you can't make it here, gravel shipping usually costs
about $10 per box using USPS Priority flat rate boxes.
