I first saw Bumblebee Jasper (?) two or three years ago at the Tucson Gem Shows. I should have bought some at that time, but I really thought it was phony like Rainbow Casilica that the Mexicans claimed was a real find. They even went to the trouble of “dummying” a mine up to appear like a seam of the Casilica was a natural occurance.
Bumblebee Jasper has amazing yellows, oranges and blacks and if any rock looked artificial this one does. Unbelievably, this stuff is REAL. It’s from hydrothermal vents on Mount Papansayan on West Java, Indonesia. The yellow and orange coloration is caused by Sulfur that is then opalized and silicated. Other trace elements are also present, producing a striking range of colors and pattern with the yellow and orange stones highlighted with black, gray, tan and crystal.
Although claims are made that this material is Jasper, it is much softer than most Jaspers I have cut, and is closer to Onyx in hardness. The banding also resembles Onyx. Onyx is a form of Chalcedony as is Agate and Jasper, but is generally softer. Agates allow light through them, and Jasper and Onyx are generally opaque. Sometimes Jasper and Onyx are combined with Agate to create combination Silicates. Bumblebee seems to be one of those combination gemstones. I sense variable hardnesses within the Bumblebee, making it somewhat prone to undercutting.
Only a small amount of Bumblebee Jasper is produced from the source each year, and most of it is snapped up for the Chinese bead trade. We saw Bumblebee beads in Tucson, but they were expensive. I saw some rough, but the quality of it was very Iffy.
The nature of Bumblebee is to have varied hardnesses and also have many holes and flaws. I found it best to bite the bullet and buy quality, finished cabs. They were very expensive, but had no issues as seen in the rough.
I made a few Bumblebee pendants that I am sharing in this blog and post up on the website. There is no other natural stone that is even close to the patterns and coloration of Bumblebee Jasper, but if you want one, I would get it now. The quantity is very limited.
