Bottle openers featuring Australian mineral photo thin section art in resin

Bottle openers with stainless steel opener and embedded mineral photography thin section art image in resin.
The images in the bottle openers shown are magnified views (under crossed polars) of various Australian Minerals. The images were captured by my sister Sue during her career as a geologist and is one in a series of Australian Minerals. This is how Sue did it:
After cutting and roughly trimming with a diamond tipped saw the rock is slowly cut, ground and then polished to a thickness of 0.03mm (30µm). Using resin to hold this incredibly thin slice of rock onto a glass slide the constituent minerals are now ready to be viewed under a polarising microscope. The diagnostic colours produced by projecting various wavelengths of light through the rock sliver, in conjunction with mineral shape and its association with other minerals are used to determine the mineral type. The diagnostic colours and shape of the mineral can also tell the experienced petrologist the approximate chemical composition of the mineral.
Working with Sue's Australian Minerals series in her memory, the images have been printed on a special photographic paper allowing me to embed the images in resin in a mould, making a stylish addition to your bar or a great gift idea for your geologist or rockhound friends, or someone who just appreciates beautiful objects!
I will be making more mineral photo bottle openers featuring all of Sue's Australian Mineral Series. The openers shown are the ones I have made so far and correspond to the descriptions in the item selection drop-down list. As I make more openers I will upload photos of them into the listing.
