Ein unscharfes Nahbild zeigt ein kristallines Objekt auf einem braunen Untergrund. Das Objekt hat eine sternförmige Form und besteht aus mehreren langen, dünnen, flachen Kristallstücken, die von einem zentralen Punkt ausstrahlen. Die Kristallstücke sind von hellblauer Farbe und wirken durchscheinend. Der braune Untergrund ist körnig und uneinheitlich strukturiert. Das Bild ist scharf fokussiert auf das kristalline Objekt, wobei der Hintergrund unscharf ist. Bereitgestellt von @altbot, privat und lokal generiert mit Gemma3:27b 🌱 Energieverbrauch: 0.095 Wh

The Smithsonian acquired two “ulu” silver pendants with tugtupite cabochons (ulu is an all-purpose knife traditionally used by Inuit, Yupik, and Aleut women), designed and created by Mike Møller. These are the first tugtupite gems acquired for the National Gem Collection. https://naturalhistory.si.edu/object/nmnhmineralsciences_14272125?geogallery=Tugtupite&node=14624I’m

Kyanite is a naturally occurring aluminum silicate mineral that typically forms as bladed crystals, and occasionally it occurs as radiating masses of crystals. The name kyanite is derived from the Greek word kyanos which means “blue.” Gem quality kyanite has a royal blue color similar to fine sapphire. This material is highly prized by those who cut gemstones. Kyanite can be cut en cabochon, faceted, or fashioned into beads, however its variability in hardness and color zoning can make it difficult to fashion and facet. Transparent intense blue kyanite is beautiful and is considered to be an exotic gemstone because it is not often seen in jewelry. Kyanite is predominately found in shades of blue and green, but it can also be yellow, white and orange. This 5.87ct gem is an intense deep blue color and the largest and finest kyanite from Nepal in the National Gem Collection. Smithsonian Museum"

Johannes Vermeer, Girl With a Pearl Earring ca 1665 Medium: Oil Support: Canvas Size: 44.5 cm x 39 cm Art period: Baroque Mauritshuis, The Hague Painting This is the famous painting of the young Dutch woman in gold jacket with white collar, gold and blue turban with large pearl earrings looking over her shoulder at the viewer, against a near-black background. “Vermeer, Girl with a Pearl Earring is an exceptional example of Vermeer’s genius, it is a portrait of an unknown girl or maybe a generalized female head (called a ‘tronie’ in Netherlands). The pigment analysis revealed a limited palette consisting of red, brown and yellow ochre, natural ultramarine, indigo, lead white, and the rare yellow pigment weld (luteoline).” Red ochre is hematite.

An image of a cave painting and analysis of pigments used. There’s a rotund beige horse outlined in black from the Lascaux caves, and a collection of squares of browns and black labelled with the mineral pigment used to produce these colours at Lascaux. 6 squares are due to Goethite in umbers and browns. 2 dark browns from Hematite. Black from magnetite. 5 brown squares from: Lepidocrocite, Akaganeite, Maghemite, Feroxyhyte, Ferrihydrite and Fe(III) hydroxy-Sulfate.
