Would it be too much to ask for help on what a fusion of Sunstone and either a Yellow Pearl, Yellow Opal, or Bumblebee Jasper would look like?

So Sunstone + yellow Pearl = ?

Sunstone + yellow Opal = ?

And sunstone + bumblebee Jasper = ?

Thank you!

no not at all!, hopefully this fulfills your request!

Sunstone + Yellow Pearl - Corkite - Montebrasite - Ettringite

Sunstone + Yellow Opal - Alacranite - Childrenite -  Francevillite

Sunstone + Bumblebee Jasper - Rauvite - Septarian - Schalenblende

I might have art block but i can always draw Ettri

Indian Star Ruby · A rare ruby guard type

Jordanite · A medium ranking gem, she is very quiet and correct

Ettringite · Her hair is very big as her fame and importance

Hope u liked it!

Manganite on Ettringite

Rare and fragile, these beautiful hexagonal crystals in the photo comes from the only source of this gemmy yellow sulphate mineral: The N'Chwaning Mines in South Africa's Kalahari manganese fields. Elsewhere it occurs as microcrystals, usually white to colourless. The mineral needs careful storage, since it is hydrated, and as water evaporates from the structure the colour turns white. It was first discovered in the Eifel Volcanic Field in Germany (see http://on.fb.me/1nJ2QtO), named in 1874 for the Ettringer volcano that spouted the lava flows which are its type locality. It forms when volcanic rocks intrude into limestones and freeze, baking the surrounding rock into a contact metamorphic aureole and spitting out element laced juices as they slowly freeze. This produces an exotic chemistry as the distillations of crust or mantle encounter limey rocks, forming a mineralogy known as skarns. Here the yellow Ettringite on matrix is accompanied by a lovely octahedron of Manganite, the most common oxide of this element.

Hashemite: BaCr6+O4; Ettringite: Ca6Al2(SO4)3(OH)12·26H2O

Locality: Lisdan-Siwaga Fault, Hashem region, Amman, Jordan

“Group of brown, slightly greenish, sharp, transparent crystals of hashemite on matrix with lemon-yellow prisms of chromate-bearing ettringite. Also present, but not in the photographs are crystals of calcite. This is from the type locality for hashemite approx. 60 km southeast of Amman, Jordan. Specimen acquired from Jason B. Smith”. Andreas Schloth
