TT93AH1: A complete floater Beryl (aquamarine variety) crystal with parallel growths and rich with dissolution surfaces and very sharp edges. The crystal, with small black oxide inclusions, has a very vivid and uniform blue color.
Xanda Mine, Virgem da Lapa, Vale do Jequitinhonha, Minas Gerais  Brazil

Specimen size: 6 × 4.6 × 3.2 cm = 2.36” × 1.81” × 1.26”

NFB48AO5: Beryl crystal (aquamarine variety) with very sharp crystal forms, translucent, lustrous, sea-green in color and with inclusions. On matrix, with aggregates of lamellar Muscovite crystals.
The specimen comes from the collection of Santiago Jiménez who, especially in the 1980s and '90s, put together an excellent collection with a very good representation of the mineralogy of northern Spain.

EYA26AP1: 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.

Specimen size: 1 × 0.8 × 0.6 cm = 0.39” × 0.31” × 0.24”

SV3440TJJ:

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.

TC86AD5: A novelty at Tucson 2016. Parallel aggregates of very sharp and well defined octahedral crystals, with sharp skeletal growths. According to our sources the site is not supplying new specimens for collectors so new finds are not expected. We analyzed these Golds and they are really special. They contains a 99.1% Gold and about a 0.5 % Rhodium, which is quite uncommon. We’ll send a copy of the analysis to the buyer.
