Tranche de la pallasite de Seymchan (qualité AAA +) d'un poids de 19,70 g pour environ 70 mm de hauteur large et 40 mm de large pour une épaisseur de 2 mm.
Un certificat d'authenticité signé, intégrant la photo de la pallasite, accompagne la météorite.
Tranche de la pallasite de Seymchan de qualité AAA+. Cette tranche révèle aussi de superbes cristaux d'olivine, la lumière passant à travers, dont certains sont de qualité gemme ce qui est extrêmement rare pour les pallasites.
Les pallasites sont considérées à juste titre comme les reines des météorites, les plus esthétiques, spécialement lorsqu'elles sont coupées en tranches fines et polies. Ce groupe de météorites consiste en un alliage de fer-nickel qui semble "baigner" des cristaux d'olivine de couleur jaune miel à vert olive.
