“Volcano” is a vey fitting nickname for those !
In the spirit of naming the notable pieces , I would like to propose “Beautyberry” for the scarce opaque black with lavender swirl marble, which deserve a name . This keeps them under the ‘“Berry Family “ that Val started with the similar “Blackberry “.
Beautyberry is a native shrub of the Eastern woodlands ,with bright purple/lavender berries that are similar to the swirl colors in this marble. I hope this nickname entry gets some consideration. 😁
