Tillbaka

When synthetic diamonds became available in larger quantities it revolutionised the lapidary industry. Anyone could afford high quality abrasives for #gemcutting and knowledge of #lapidary arts spread & developed quickly from the early 1960s onward. There would be no fancy cuts or hobbyist lapidaries without synthetic diamonds. Picture by me of synthetic diamonds produced by #ASEA in the 1960-s at the #MuseumOfTechnology archive, #Stockholm. #gemmology #gemstonecutting #diamonds #gems #gemology
