Piedra is based on an orange blossom core with juicy citrus notes enhancing this core, and extending notes that include patchouli, vetyver, labdanum, and clove bud. It's very deep and dark with heady floral notes, and it lasts a while on the skin, far longer than the same blend would if made in alcohol.
Violetta began with a core of orris root and violet leaf, then I added enhancing notes of boronia, tuberose, and jasmine sambac, and extending notes of oakmoss, patchouli, elemi absolute, almond extract, and different vanillas. This one is more vanilla-violet than straight violet, so it lasts on the skin for an hour or more, in a mostly oakmoss and vanilla sort of way. It isn't as bright and cheery as violets alone, instead, it expands on the forest earth in which the violets grow.
There are a few more coming, maybe some resurrections, as I posted earlier here. Solid perfume is perfect for the autumn and winter months as they last longer on usually drier skin.
