DaG 669 and DaG 671 weigh 926 and 485 g, respectively, and were found in close proximity.  The two are very likely paired. Classification and mineralogy (L. Folco and C. Ferraris, MNA-SI): cumulate eucrite, basaltic eucrite and diogenitic clasts are embedded in a fragmental matrix along with sparse cryptocrystalline spherules; cumulate eucrite clasts have medium-grained gabbroic texture, dominated by pigeonite (En_60–48Wo_5–11) and anorthite (An₉₁), and contain minor augite (exsolved phase En_37–42Wo_36–42), Ti-chromite, ilmenite and iron sulfide; basaltic eucrite clasts display fine-grained subophitic texture, containing exsolved pigeonite (En₄₂Wo₁₄, showing augite lamellae, En₃₇Wo₃₈, in an enstatitic host, En₄₅Wo₂) and bytownite (An_71–76), with abundant Fe-Ni metal and chromite, plus a silica phase; diogenite clasts have fine-grained fragmental texture, with abundant fragments of zoned enstatite (cores: En₇₈Wo₁; rims: En₆₃Wo₁) up to 0.5 mm in size, and minor intermediate olivine (Fo₅₁), bytownite (An₈₃Or₂), iron sulfide, ilmenite and chromite; lightly shocked. Specimens: main mass with anonymous finder; type specimens 9.3 g (DaG 669) and 12.5 g (DaG 671), plus polished thin sections at MNA-SI.
