| A tissue and a bead nucleated pearl cut in half...
At least pictures of different shapes.
Some pictures of (badly) treated and natural pearl surface under relevant magnification...
A shell with blister pearl on (unless that's common sight in curio shops nearby).
And would definitely include a world map with pearl-producing spots among the slides.
Speaking of slides, there were some magnificent pictures showing the range of colors of Cortez pearls posted here, better resolution versions would work great to show how far diversity (= choice) can go if one takes the time to look.
Would imagine that a range of examples for black lip colors would be expensive, unless you can borrow a nice multicolor strand for the course...
Who will be the lucky students? |
