Examples
“The truncating of the lower cone forms the tiny facet known as the culet, which lies opposite to the table and is parallel to the latter [see B, Fig. 13, cut”
A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public
“The especially large open culet on the bottom of the stone was a portal for the owner to go into the diamond and see whatever he wanted; this was part of its magic.”
“The size of the culet let the small facets produce a fire.”
“Its fourfold symmetry was reflected on its culet facets as well as the split-star facets.”
“Such well made brilliants when held up to a bright light appear almost black -- that is, they fail to pass any of the light through them (except through the tiny culet, which, being parallel to the table above, passes light that comes straight down to it).”
A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public
“However, one must use much judgment in such a case, as sapphires, like other corundum gems, frequently have their color irregularly distributed, and the skillful lapidary will place the culet of the stone in a bit of good color, and thus make the whole stone appear to better advantage.”
A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public
“The stone is then reversed and 24 facets, and the culet, polished on the back.”
