This stunning specimen looks bright and new, but is definitely from the classic mid to late-1800's finds of these sharp Calcite twins, that reigned as the kings of twinned calcite for a century. Heart twins from Egremont are an "essential classic" in that they are beautiful and important at the same time, and I think add depth to any collection that has more common styles of Calcite from modern finds. There still is nothing else like these around from other locales. Most of these twins were collected in the 1860s to the 1880s, when famous British dealer John Graves handled a majority (there are famous ads for these heart twins, as described in the book, The Sparry Garniture). For it to survive to today in such condition usually means it was in a museum drawer for 100 years. Also, such clarity, such bright luster, is extremely rare in combination for these. Being completely colorless and totally transparent makes this piece stand out even in a case of fancier gem crystals, literally like a "jewel." This large twin is very clean with only a small contact on one side (and you can angle it a bit, so you do not really see it at the best display angle), and not marred by any internal spots of Hematite stain or matrix inclusions. In person it is bright and shiny, no hint of old dinginess. This twin is thick, making it robust. yet still very elegant, as most are a bit thinner. From the notable worldwide collection of George Elling. It also happens to be important for the size...most of these that survive are large, relatively clunky compared to this beautiful large miniature/small cab boundary in size.
