NWA 11639 ~ Achondrite Ureilite Slice ~ Graphite / Diamond Aggregates ~ 5.61 g

This NWA 11639 achondrite ureilite was discovered in 2017 and has a total known weight of just 583 grams. The meteorite is HIGHLY resistant to cutting and polishing, revealing many visible graphite and diamond aggregates. The silicate matrix was leveled during polishing, causing the harder inclusions - likely diamonds - to stand out due to their extreme difficulty in cutting and polishing. This effect is particularly noticeable when running a finger over the surface. Picture 1 ~ Shows a number of graphite / diamond aggregates circled in red, and one in yellow Picture 2 ~ The slice without the graphite / diamond aggregates circled Picture 3 ~ Enlargement of the largest (2mm) aggregate (circled in yellow in picture 1) Picture 4 ~The photograph was taken at a 45-degree angle using a digital microscope with reflective cross-polarized lighting and photo stacking software. This picture more accurately depicts that the larger 2mm graphite/diamond to see that it is raised above the matrix. The light grey/white

color attachments are silica grinding powder. Pictures 5 & 6 ~ Photographs taken with a 1cm cube and COA showing both sides. Shipping worldwide!
