Yellow Rock is situated on the eastern, lower slopes of the Blue Mountains and the western side of the Nepean River extending back some way from it, the elevation rising from the river to a peak of 245 metres (804 ft) AHD .
Citrine is the yellow form of quartz. Its coloration comes from the inclusion of iron ions in the color center of the crystals. Citrine and amethyst are formed from the same stock, but citrine requires higher temperatures during its formation to gain the yellow-gold coloration it's known for.
Orpiment is known for its strikingly bright yellow color, though it can also be bright orange or lustrous brown. The name Orpiment is derived from the Latin Auripigmentum, meaning gold pigment, in reference to its color and historical use as a golden-yellow pigment.
Yellow Rock was once a dairy farming community and is named for the yellow sandstone cliffs of the escarpment. The local yellow rock stone was used to construct many buildings in the township of Albion Park.
Clarity: Citrine is a very clear gemstone, with its clarity being one of its defining characteristics. It has a bright yellow hue ranging from pale yellow to golden brown and is often transparent or translucent.
A number of yellow minerals are rare in nature but common in rock shops and at rock and mineral shows. Among these are gummite, massicot, microlite, millerite, niccolite, proustite/pyrargyrite, and realgar/orpiment. Many other minerals may occasionally adopt yellowish colors aside from their usual colors.
Rare though it is, yellow does in fact occur in quartz in Nature, if seldom, when there are traces of iron in the silicon dioxide. Historically, it has been found in Spain, on the Scottish island of Arran, in France, Hungary and in several mines overseas.
Rising dramatically from the Central Australian desert, the huge red rock of Uluru is one of Australia's most iconic attractions. Formerly known as Ayers Rock, Uluru is made of sandstone about half a billion years old.

The major ingredient of all the ochres is iron(III) oxide-hydroxide, known as limonite, which gives them a yellow colour. O, is a hydrated iron hydroxide (limonite) also called gold ochre.
Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.
Popular light yellow crystals include Citrine, Yellow Fluorite, and Sulfur.
Sulphur has the chemical symbol S and atomic number 16. It is nonmetallic and multivalent. At room temperature, sulphur is a bright yellow, crystalline solid. Sulphur burns with a bright blue flame and melts into a red liquid.
Yellow Jasper is an opaque, microcrystalline variety of Quartz with large, grainy crystals rather than the fibrous layers of Chalcedony or Agate. It occurs in nodules or as fillings in fissures and may be found the world over.
Being a banded microcrystalline form of mineral Quartz and occurring in visible crystals, Yellow Agate is a translucent to opaque in material. Its chemical formula is SiO2 i.e. Silicon Dioxide. Possessing a hexagonal crystal system it has a specific gravity of 2.6-2.7.
There are myths and magic embodied in Uluru, and mysteries written across its face by an ancient people, but that is not surprising as this rock is thought to be one of the oldest on the planet and is dated at over 500 million years old.
Burringurrah (Mt Augustus)
Burringurrah, in Wajarri country about 1,000 km north of Perth in Western Australia, is claimed by some to be the "world's largest monolith" and "biggest rock in the world".
Some of the many other lapidary rocks from Australia include: rhodonite, print stone, chrysoprase, crazy lace agate, peanut wood, Queensland agates, and Queensland petrified woods. Other minerals found in Australia include crocite, diamonds, sapphires, copper ore minerals, and much more!
The Jack Hills are a range of hills in Mid West Western Australia. They are best known as the source of the oldest material of terrestrial origin found to date: Hadean zircons that formed around 4.404 billion years ago.
Australia. In Australia, barbecuing is a popular summer pastime, often referred to as a "barbie". Traditional meats cooked are lamb chops, beef steak, and sausages (colloquially known as "snags").
Walga Rock, also known as Walghana, is five kilometres in diameter and 1.5 kilometres in length and is Australia's second-largest monolith after Uluru.
The most plentiful yellow gemstones in the marketplace are citrine, sapphire, topaz, tourmaline, and transparent opal. Other varieties include yellow andradite garnet, spessartine and Mali garnets, beryl, sphene, zircon, spodumene and transparent varieties of labradorite and orthoclase feldspar.
Citrine and Lemon Quartz
By far, the most popular yellow gemstone is citrine, the modern November birthstone. This variety of quartz is yellow to orange or brown, and, due to the abundance of quartz in the Earth's crust, it's an inexpensive option. Still, this mineral is a durable jewelry stone.
Yellow quartz is not as valuable as diamonds or emeralds, but its worth may differ based on its size, clarity, and cut.
