Well, the difference in the finishes, is that one is in natural color and the other 2 dye painted with alcohol, use you can give is for small gifts or for an engagement ring (an original detail).
The type of wood that I used was a few trees pruned at home, here in Mexico is called "tree thunder."
They are small jobs, have long measuring approximately 8 cm. width 4.5 cm and 3.5 cm height.
Thanks for your questions and comments.
