Grape Agate/Botryoidal Amethyst
NEW FIND!
This is very interesting new material that was introduced to the market in the latter half of 2016. It was discovered
some years back along one of Indonesia's island coastal areas, Manakarra Beach in the Mamuju Area, Sulawesi
Barat Province, West Sulawesi Island, Indonesia. Since its discovery the Indonesian government had not allow it to
be collected or exported until late 2016. We found an exclusive import dealer at the  2017 Franklin, NC Show who we
buy from every year. The specimens we choose are nice lavender colors with associated moss-green Celadonite
making a superb contrast. At the 2020 show we found some specimens with amazing small clear Quartz crystals on
the specimens as well.

These have been called Grape Agate, Grape Chalcedony, Amethyst Grapes and probably more names we have yet
to hear. We originally called them Grape Chalcedony Agate due to their color, botryoidal formation and their cluster
formation. Later just Grape Agate as they form combinations of fine brilliant purple radial aggregates "balls" that
resemble a bunch of grapes that have a stunning three-dimensional form and enticingly sparkling luster. When
viewed through Opti-Visors or magnification, each individual "ball" has finite crystallized drusy-like surfaces. What
drew us as a dealer and provider for collectors to this new find is that it is a common mineral with an uncommon color
and habit in the mineral world from a new locality. Purple is a highly desirable color for mineral specimens as
evidenced by the demand for Amethyst, Opalized Fluorite (Tiffany Stone) and Purple Fluorite to name a few.
Like most new discoveries, it’s unpredictable to say how much more will be available, and what quality the
specimens will be. Normally the best material tends to find its way to the market first, and the prices rise dramatically
with demand and reduced availability.  Prices have been all over for this material. Specimens at many high end
dealers are still priced in the thousands of dollars. Specimens tend to be more affordable in the USA compared to
what we have seen internationally.  We hope you like these specimens as much as we do!

Grape Agate
Tiny spheres of purple quartz with a botryoidal habit.

What Is Grape Agate?
Grape agate is a marketing name for purple aggregates of tiny quartz crystals with a spherical (botryoidal) habit. The
name reflects their purple color and how they occur in clusters that resemble bunches of grapes. This material is
found in the Mamuju area, near the western coast of Sulawesi, an island of Indonesia. Grape agate entered the
mineral market in 2016. Its popularity quickly spread through mineral shows, rock shops, websites, and online
marketplaces. Specimens with a fun appearance and an interesting name like grape agate market themselves.
The "grapes" of these specimens are tiny. They range between about two and eight millimeters across. Although
purple is the best color to match the "grape" name, some specimens have grapes that are white, gray, green, or blue.
Grape, Yes. Agate, Maybe Not.
The name "grape agate" has stuck as a marketing term. However, the name is a misnomer. Misnomers are names
that are scientifically incorrect. There are no arguments with "grape" because of its purple color. But, the use of
"agate" as a species/variety name draws objections. Here is an analysis...
Grape Agate: This name is inappropriate because agate should have parallel internal banding. The name agate
also implies quartz with a microcrystalline texture; however, most of the grapes have a drusy surface - making them
megascopically crystalline.
Grape Chalcedony: Like agate, the name chalcedony implies quartz with a microcrystalline texture.
Grape Quartz: The name quartz fits better than both agate and chalcedony. But, the appropriate name for purple
quartz is amethyst.
Botryoidal Amethyst: The name "amethyst" better honors mineralogical and gemological definitions, and the
adjective "botryoidal" communicates a rounded shape. So, this author concludes that the name "botryoidal amethyst"
is a name that is scientifically correct, but is not as much fun as "grape agate".
