This is why well-cut crowns are some important: the first image is of a new aquamarine asscher on the dop & half finished, the second is of the same stone, but with the crown I favor for asscher designs.

Well, suffice to say that they’re almost impossible to source when you want one. That’s why I invested in this large, untreated yellow sapphire at the AGTA show in Tucson this … Read More
