Earthlike Gems

This is a list of precious and semi-precious stones available on Earth, and therefore realistic and acceptable for Starmourn settings.

Amethyst is a type of quartz stone that forms naturally in geodes of varying size, or is synthesized via hydrothermal growth. Coloration can be highly dependent on traces of iron and other minerals, resulting in a variety of possible colors from pale lilac to deep purple.

Ametrine is a type of quartz stone closely related to amethyst and citrine, in which traces of iron oxidize naturally at different rates due to temperature gradients, resulting in an ombre effect between a purple and orange coloration.

Aventurine is a type of quartz stone that features a metallic glitter called aventurescence, which can be more or less pronounced based on the transparency of the stone. Aventurine comes in a variety of colors, including orange, brown, yellow, blue and grey.

Carnelian is a type of chalcedony stone, also known as sard, that has a brownish-red coloration caused by traces of iron oxides. Varying widely based on the concentration of these oxides, the carnelian offers a range of colors from pale orange to an almost-black brown.

Citrine is a type of quartz stone with a cloudy or smoky appearance that rarely forms naturally, requiring precise formation conditions and traces of ferric hydroxide to produce a range of colors from pale yellow to amber-hued to glassy brown. Synthetic citrines tend to form with more rigid lines, making them resemble yellow topax.

Jasper is a type of opaque aggregate stone that can be found in virtually any color based on the mineral contents of the formative sediment. Several notable pattern varieties can be found in the spectrum of jasper colorations, including dendritic jasper, the abstract striations of picture jasper, the broken branches of brecciated jasper, the starkly contrasting layers of kaleidoscope jasper, ring-speckled poppy jasper and the gently curved striations of river jasper.

Milky Quartz is a common type of quartz stone with a clouded white coloration caused by traces of gas, fluid or both.

Onyx is a type of chalcedony very similar to agate, with parallel striation bands, usually white or black against the color of the stone, which is most commonly found in black, yellow, green and red. If the striations are red, the variety of stone is called sardonyx.

Rose Quartz is a type of quartz stone with hues ranging from pale pink to rose red, caused by trace amounts of metals in the crystal. Rarely, traces of rutile in a rose quartz can cause an optical asterism to appear in the cut stone.

Smoky Quartz is a type of quartz stone occluded with traces of aluminium, which can vary in clarity form opaque to translucent, and in color from pale grey to black based on the concentration of these impurities.

Tiger's Eye is a type of quartz stone with an optical chatoyance, with a golden to red-brown coloration and a silky lustre. An accepted in-world name is Tigrid's Eye.

Tiger Iron is a type of rock composed of tiger's eye, red jasper and black hematite forming in undulating striations of contrasting colors. An accepted in-world name is Tigrid's Iron.

Vermarine is a type of quartz stone, also known as prasiolite, that has traces of silicon dioxide that offer the stone a varied green palette, from pale green to forest green. Cloudy impurities can occlude the stone with a milky color.
