Fresh & Fruitful 🍇 . Although this one lacks the deep purple colors common for this variety of quartz, we selected this piece for its wondrous and unique structural formation.

Grape Agate, also known as Botryoidal Amethyst. Know I know how you geologists like to tussle, so let me elaborate. "The botryoidal amethyst aggregates look similar to grapes in shape and color and often receive the nickname “grape agate.” However, “agate” is not an entirely correct term here, as most of the crystals have a drusy surface rather than a microcrystalline texture. We land on a better suited name of “quartz v. amethyst” for these specimens, giving the most accurate description to the specimens’ mineralogy." - cited from Mindat. So if you know more than the actual geologists who have come to this conclusion- take your dissertation to THEM. Other than that, enjoy this rock ☺️ - - #grape #grapeagate #botryoidal #botryoidalamethyst #mindat #minerals #quartz #variant #crystals #jadesgemshop (at Scranton, Pennsylvania) https://www.instagram.com/p/CcEWz74lVCG/?utm_medium=tumblr
