VERY RARE Selenite formed on branch
Absolutely the most unique Selenite Crystal formation found in California by Maggie McShan
(1915-2004) This is from her collection in Needles, California.
This desirable specimen has Gypsum
Selenite crystals that formed on a shrub branch and was found with several other specimens with smaller
branch inclusions.
This specimen is EXTREMELY Fragile. Care will be taken, packing this in a Medium
Flat Rate box with lots of padding
, but some of these crystals may be damaged in shipping. There are
currently 4 separation breaks on the branch, we suppose from the branch being flexed years ago. This
specimen is estimated to have been collected in the 1960's and was one of Maggie's favorite pieces.

This piece weighs 2.5oz or 0.15 lb (72g)
The crystal formation
measures 10" (25cm) long on a branch that is 11.75" (29.5cm) long with a crystal growth formation from
1/2" to 3/4" (12.7 to 19mm) in diameter on a 1/4" (5.7mm) diameter branch the widest crystal growth branch off point
measures 1.5" (40mm)

Orange Selenite
Orange Selenite is a very impressive stone. It has a peachy
orange color and has white fibrous strands as you can see from
the rough sides. It carves and polishes easily and displays a
brilliant orange (see picture on right side) when backlit or placed
on a lighted display. Most of this is found in Pakistan or Morocco
and is rather difficult to find quality specimens for carving as
other minerals form in the selenite. Most of the less pure
specimens are made into candle holders for Tea Light or Votive
styles of Candles.

This Gypsum Selenite is from Hanksville in Wayne County, Utah
Gypsum Selenite has many interesting properties, and has very unique crystal habits. Many Gypsum
crystals are found perfectly intact without distortions or parts broken off. Such crystals are found in a clay
beds as floater crystals, where they fully form without being attached to a matrix.  Most Gypsum has some
matrix attached. Clear or colorless Gypsum is often referred to as selenite Ice due to its high sheen.
Fibrous compact white Gypsum is referred to as White Gypsum Satin Spar due to its satin sheen. Gypsum
has the same composition as the mineral Anhydrite, except it has water in its structure. Many Anhydrite
specimens absorb water, transforming into Gypsum. Gypsum specimens show evidence of the
transformation by developing disintegrating layers that appear to spread due to the expansion from the
added water. Gypsum specimens should only be cleaned with water. Soaps and detergents should never
be used because they can infiltrate the crevices of a crystal and ruin its beautiful luster.

Gypsum is one of the most common, rock-forming minerals, developing thick beds formed by the evaporation of
extremely salt laden waters. Gypsum is associated with halite and sulfur. It is deposited from lakes, seawater, hot
springs, volcanic moisture, and sulfate solutions in underground veins. Anhydrite in underground veins can be
converted into gypsum by hydration from groundwater close to surface areas. Gypsum dissolves over time in
water, and is rarely found in the form of sand. A well known oddity is the White Sands National Monument in the
state of New Mexico. The unique conditions there have produced a 275 square mile area of white gypsum sand.
In 1933 President Herbert Hoover declared the gypsum dunes a protected national monument to prevent
commercialization of the area.

When heated under appropriate conditions, gypsum forms plaster of Paris. Gypsum is extremely useful for many
practical applications and for works of art. In particular, it is used for wallboard for buildings, as a component of
concrete for the construction of highways and bridges, and as a soil conditioner for agriculture. The Clear variety
is called selenite. The translucent variety, called alabaster, is a valuable ornamental stone. When converted to
plaster of Paris, it is used in sculpture, architecture, fire protection, and theatrical sets. There are many formations
of Gypsum that make outstanding collection specimens, and it is a favorite of rockhounds!
