I often see alembics being made with either purpleheart or ebony laminated body accents but I don't see any mention of it though the quote generator.
 
Are there certain models where this is a standard no cost feature?
 
What are the aproximate increases in price for having either purpleheart or ebony body accents done?

As far as I know, accent laminates are standard on every Alembic. The wood is chosen for maximum contrast. I'm not Alembic, but I don't think there is any extra charge for any accent laminate choice. Just my $0.02.
