2.7 x 1.8 x 1.2 cm.

4.5 x 3.7 x 2.6 cm. Ludwigite is a rare magnesium, iron borate and this rich, old-time specimen is from the Type Locality – Ocna de Fier (Moravica), Banat, Romania. A vein of silvery bright sulfide microcrystals is sandwiched between waxy, black, fibrous ludwigite crystals. Very highly representative of the rare species and Type Locale. Comes with an old, faded, expertly handwritten label. The collection this came out of was a museum stash dating to prior to World War I.
MD-206355 - Ludwigite - - Archived Pomeroy Mine, Georgetown District (Southern Cross District; Cable District), Deer Lodge Co., Montana, USA cabinet, 10.5 x 8.2 x 4.8 cm.
10.5 x 8.2 x 4.8 cm. Another relatively unknown mineral, ludwigite (Mg2Fe3+BO5) typically forms in magnesian iron skarns and contact metamorphic deposits. It forms a series with vonsenite. In this large and rich specimen from the Pomeroy iron mine in Montana, it has formed bright black, radial fibrous aggregates. Old material and a rare Montana piece of some note. Ex. Elling Collection.

8.9 x 6.1 x 3.8 cm. Ludwigite is a rare magnesium, iron borate and this old-time specimen is nearly solid ludwigite with just a bit of matrix. Radial aggregates of lustrous, black, metallic, acicular ludwigite crystals cover all surfaces on this piece. This is extremely uncommon material from the Alta Stock of Utah.

MD-257483 - Forsterite (Var: Peridot), Ludwigite - - Archived Sapat Gali (Soppat; Suppat; Sumpat), Manshera, Naran-Kagan Valley, Kohistan District, North-West Frontier Province, Pakistan miniature, 3.2 x 2.0 x 1.6 cm.
3.2 x 2.0 x 1.6 cm. This crystal has unusually good, intense lime-green color and internal clarity. You can see inside the needle-like crystals of ludwigite, for which this locality is known.

Ex. Laura and Stevia Thompson Collection.

A fat, and exceptionally well-terminated peridot crystal! Peridot crystals of size are usually somewhat rounded, and to get a crystal of this gemmy, transparent quality, so thick, and with such a wonderfully basal termination, is very uncommon. As an added bonus, it is included by sharp, vertical, crystals of the rare species Ludwigite , which makes for a stark contrast. 2.8 x 2 x 1.1 cm

T5127 - Peridot with Ludwigite inclusions - $ 1750 SOLD Soppat, near Dassu, NWFP, Pakistan miniature, 5.2 x 1.4 x 1.1 cm
WOW! This is a super-sharp, transparent, crystal of peridot with EXCEPTIONALLY SHAPR FORM. Most of them, especially large ones , tend to get very rounded for some reason. This is one of the largest sharp crystals I have seen, in fact. It is made more interesting by inclusions of acicular ludwigite, a rare species, that streak throughout the lime-green peridot.
