The "grape agate" or ball formed Amethyst from this region is incredible, pretty and affordable. One of the mineral kingdom's best bargains, the color and forms are a great value.

stock #SOLD 21.1-368
Mamuju area, Sulawesi Barat province
Sulawesi Island, Indonesia
3.1 x 2.4 x 1.7 CM (thumbnail)
price: $0
Late Summer 2021

The "grape" forms of these Indonesian Amethysts are well-known and still can be found on the mineral market. This top vivid color and bright sparkling luster is much less common. This is a complete floater piece with excellent form, definition and deep grape color, selected with care. These are still an excellent value. We understand the source is now mostly just producing dull or light color materials.

HOLD Amethyst - Grape Chalcedony/Agate
stock #HOLD 17.1-285
Manakarra, Mumuju area, Sulawesi Barat Province
Sulawesi Island, Indonesia
6.3 x 5.7 x 2.7 CM (cabinet)
price: $180
new year 2021

One of the most exciting and attractive finds of the past few years were these "Grape Agates" or Chalcedony spheres from Sulawesi. Now more correctly called botryoidal Amethyst, this material is unique in the mineral world and can be incredibly attractive. This is a select piece, well-formed on all sides with the desirable bicolor (green and purple) areas. The color on this piece is a good deep grape purple and the "front" is also covered with drusy Quartz that adds the most desired sparkling luster. In fine condition as seen, better specimens from this find are among the best values on the mineral market today, however recent mining has not been producing much of the higher quality.

stock #17.1-210
Mamuju area, Sulawesi Barat province
Sulawesi Island, Indonesia
5.6 x 5.2 x 2.5 CM (cabinet)
price: $280
new year 2021

It is hard not to like the "grape agates" from the finds in and near Mamuju. The best of these are a wet looking cluster of balls with vivid purple color and sometimes with some green balls for contrast. Most have at least some damage or contacts, but this piece seems to be fully perfect. This has fine luster and color from all angles, a floater. One of our favorite finds of the past few years, the location where the best color was found is said to be finished, we hope that is not so.

Esthetic and undamaged specimen with violet colors and fine form. Attractive on all sides, a 360 degree piece. The exciting new finds of Indonesian Chalcedony now called purple grape agate has been big news in the mineral world. We looked through literally tons of material but found just a few perfect, complete, colorful and sculptural pieces. Much better than average.
