SM490EDT: Lamellar Ilmenite crystals with an irregular outline were completely replaced by Rutile and covered by very sharp Titanite crystals. They show great luster and very well defined faces and edges, with a distinct color change that shows an intense yellow under LED light and greenish under natural or fluorescent tube light.
The process of substitution of Ilmenite by Rutile here seems very similar to that already known in other locations with similar geological conditions (for example the Rutile from Zambia) and is due to hydrothermal processes associated with the deposit. These specimens, very different from the titanites previously known from Imilchil, have undergone urgent analysis that we plan to continue to carry out in more depth. We will send the buyer the information and documentation obtained so far, as well as a copy of the analyses carried out on the species present in the current specimens.
