Aquaprase is a rare and unique green stone that is believed to have originated from Madagascar. It is a variety of chrysoprase, a mineral that is composed of nickel silicate. Aquaprase is prized for its beautiful green color, which ranges from pale green to a deep, almost emerald green. This color is the result of nickel ions that are present in the mineral.
In terms of its physical properties, aquaprase is a hard and durable stone, making it ideal for use in jewelry and decorative objects. It is also quite resistant to weathering and erosion, making it a long-lasting stone for outdoor use. However, it is important to note that aquaprase can be easily scratched, so care should be taken when handling and cleaning it.
There are some restrictions to be aware of when it comes to aquaprase. It is a relatively rare stone, and as a result, it can be quite expensive. Additionally, due to its rarity, it can be difficult to find large pieces of aquaprase, which may limit the size of the decorative objects that can be made from it.
Aquaprase can be found in a few different locations around the world, including Madagascar, Australia, and the United States. However, it is most commonly found in Madagascar, where it is believed to have originated. The stone is typically found in alluvial deposits, and it is often found in association with other nickel-bearing minerals such as vesuvianite and chrysoprase.
There are several rocks, stones, and minerals that are similar in appearance to aquaprase. These include:

Polishing aquaprase using NATIONAL GEOGRAPHIC Rock Tumbler
Polishing aquaprase using a rock tumbler is a simple process that can result in a beautiful and glossy finish. Here are the steps to follow:
- Prepare the rock tumbler
Fill the tumbler with enough water to cover the stones, and add a small amount of abrasive grit. The grit will be used to shape and polish the aquaprase.
- Add the aquaprase
Place the aquaprase into the tumbler, making sure that the stones are evenly distributed.
- Turn on the tumbler
Start the tumbler and let it run for several hours. The exact time will depend on the size and shape of the aquaprase, but typically, polishing takes around 1-2 weeks.
- Check the progress
After several hours, stop the tumbler and check the progress of the polishing. If the aquaprase is still rough, let it continue to run for another day or two. Repeat this process until the aquaprase is smooth and shiny.
- Change the grit
After the aquaprase has been polished with the first grit, it's time to change to a finer grit. This will give the aquaprase a smoother and more polished finish. Repeat the process with the finer grit until the aquaprase is shiny and smooth.
- Clean the aquaprase
Once the aquaprase is polished, remove it from the tumbler and rinse it with water to remove any grit residue. Dry the aquaprase thoroughly, and it's ready to use!
With these simple steps, you can turn rough aquaprase into a beautiful, polished stone that is perfect for jewelry making or other decorative projects.
