Clearly the lack of close similarity to tektites of the rocks brought back was a great disappointment to lunar theorist. However, they took some comfort in the glass spheres contained in the soils of the Moon, and that the soils themselves were found to be more similar. Tektites are often collected by people which have few sources of income. One individual in Asia exporting tektites a number of years ago was executed by a gang of bandits, who believed he possessed a map to treasure. The inability of family members to successfully continue the business closed that source of the material forever.
Some tektites are so rare they command very high prices on the collector's market.
Others are plentiful and yet each of these is an individual and has something special about it if examined carefully. They will continue to be perhaps the most unique and mysterious rocks on our world.
