F0V-FDVDiamond (Var: Carbonado) C
Dimensions: 8 mm x 6 mm x 4 mm
Diamond Var Carbondao showing the typical porous appearance. It looks rather dull but when the light catches it right it has an almost sub metallic lustre which is more obvious in photos.
1JN-5HTSerendibite Ca4[Mg6Al6]O4[Si6B3Al3O36] , Phlogopite KMg3(AlSi3O10)(OH)2
Dimensions: 20 mm x 13 mm x 5 mm
Blue green serendibite with minor phlogopite in matrix
This is the same specimen with the ID 1157929

0A3-2CYDiopside (Var: Violan) CaMgSi2O6
Dimensions: 57 mm x 40 mm x 30 mm
Areas of violan in matrix with other minerals present. I suspect the black/dark brown mineral to be braunite.
No distinct crystals but some sections to show a blocky habit typical of diopside.

ELC-DY5Hibonite CaAl12O19
Dimensions: 17 mm x 6 mm x 3 mm
Weight: 0.95 g
0.93g part slice showing a small blue hibonite calcium aluminium rich inclusion.
This is a metal rich specimen I have taken this photo under natural light and is oriented to avoid reflection of the metal which is quite bright and detracts from the finer detail of the chondrules and CAI
0N0-Q82CR2 chondrite meteorite
Dimensions: 20 mm x 20 mm x 3 mm
Weight: 3.65 g
A slice of NWA 13336 showing the typical appearance of the CR2 class, of armoured chondrules (chondrules encased in iron.nickel sulphide shells)
This meteorite was found in 2020 and the total known weight is 290g
7UA-6EPUngrouped Achondrite meteorite
Dimensions: 24 mm x 21 mm x 1.75 mm
Weight: 1.65 g
9LN-4KTEpidote (Var: Withamite) {Ca2}{Al2(Fe3+,Mn)}(Si2O7)(SiO4)O(OH) , Epidote (CaCa)(AlAlFe3+)O[Si2O7][SiO4](OH)
Dimensions: 90 mm x 49 mm x 34 mm
Altered andesite with one surface showing microcrystaline pink crusts and veinlets of the rare manganese rich variety of epidote, withamite and the standard yellowish green epidote

YMJ-6KGEpidote (Var: Withamite) {Ca2}{Al2(Fe3+,Mn)}(Si2O7)(SiO4)O(OH) , Epidote (CaCa)(AlAlFe3+)O[Si2O7][SiO4](OH)
Field of View: 10 mm
A vesicle in andesite containing small prismatic crystals of the uncommon Mn rich variety of epidote, with minor amount of the standard green epidote.

J68-992Tinaksite K2Na(Ca,Mn2+)2TiO[Si7O18(OH)] , Charoite (K,Sr)15-16(Ca,Na)32[Si6O11(O,OH)6]2[Si12O18(O,OH)12]2[Si17O25(O,OH)18]2(OH,F)4·~3H2O , Aegirine NaFe3+Si2O6
Dimensions: 44 mm x 40 mm x 15 mm
Charoitite specimen with typical mineral assemblages. Tinaskite as orange brown radiating sprays (could possibly be tokoite) lilac charoite and radial sprays of dark green aegerine.
