EYA26AP1: Gold
Specimen from a deposit discovered in 2017 and located at some distance from the previously known locality in Serra do Caldeirão, but with different characteristics. In this case a floater group of well-formed elongated Gold crystals, with curvatures on some of their faces and edges and with spinel-law twinning.

Serra Dourada, Pontes e Lacerda, Alto Guaporé District, Mato Grosso  Brazil
Specimen size: 1 × 0.8 × 0.6 cm = 0.39” × 0.31” × 0.24”

Gold.
TJ26AH0: Gold
A novelty at Tucson 2018. The sample is from a new place, not so far from the better known Serra do Caldeirão where the gold samples have different morphological characteristics. In this case this is a floater group of crystals with dodecahedron and octahedron faces with curvatures and very well defined skeletal growths. Due to its general shape and aspect it resembles sculptures of anthropomorphic figures of old civilizations.
The specimen has been reviewed, photographed and published as a new discovery in the magazine ‘Mineralogical Record’ on page 462 in the volume 49, number 3, May-June 2018, in the Russian magazine ‘Mineral Observer’ on page 76 in the volume 23, number 2, and for the magazine ‘Paragénesis’, number 01/2018, page 126

SV3440TJJ: Gold


After the first significant gold discovery in Serra do Caldeirão in 2015 (An opportune harvest of Gold in Serra do Caldeirão claims, Brazil), there have been new small finds in the area. Specifically, this Gold is from 2017 and is from the Serra Dourada area. Compared to the others, it has an excellent color and the crystal faces are more rounded than those of golds from the Serra do Caldeirão.

EBR90AP1: Gold
Floater Gold specimen with arborescent growths of elongated octahedral-rhombododecahedral crystals and with very sharp parallel skeletal shapes. By size, weight and quality, among the best of the find. The orefield is no longer productive and new specimens from there are unlikely to appear on the market. We have analyzed these Golds and they are very special, containing 99.1% gold and around 0.5% rhodium, which is rare. We will send a copy of the analysis to the buyer.

What about the Golds from Serra do Caldeirão? Much of what happened there in 2015 is well explained in this FMF thread: An opportune harvest of Gold in Serra do Caldeirão claims, Brazil
This specimen has an excellent quality-price ratio given the good definition of the terminal faces of the crystals that show a kind of "hopper" growing.
