From Wikipedia:
Eucrites are achondritic stony meteorites, many of which originate from the surface of the asteroid 4 Vestaand as such are part of the HED meteorite clan. They are the most common achondrite group with well over 100 distinct finds at present.

Eucrites consist of basaltic rock from the crust of 4 Vesta or a similar parent body.

Based on differences of chemical composition and features of the component crystals, they are subdivided into several groups:
Non-cumulate eucrites Are the most common variety and can be subdivided further:
Main series eucrites formed near the surface and are mostly, though not exclusively, regolithbreccias lithified under the pressure of overlying newer deposits.

Stannern trend eucrites are a rare variety.

Nuevo Laredo trend eucrites are thought to come from deeper layers of 4 Vesta's crust, and are a transition group towards the cumulate eucrites.

Cumulate eucrites are rare types with oriented crystals, thought to have solidified in magma chambers deep within Vesta's crust.

Polymict eucrites are regolith breccias consisting of mostly eucrite fragments and less than one part in ten of diogenite, an arbitrary dividing line from the howardites, which are related in structure. They are comparably rare.

Eucrites get their name from the Greek word eukritos meaning "easily distinguished". This refers to the silicate minerals in them, which can be easily distinguished because of their relatively large grain size.

John, I agree ... also one of my favorite eucrites. 16 gr + 1.4 gr + 0.94 gr in my collection. The 16 gr complete and crusted slice is beautiful, veined and rich in anorthite.

Dhofar 007... I recall some large individuals were sold from this find. It is one of may favorite eucrites.
