Default Shape confusion

I've noticed beads described as donuts as well as rondelles. The shape look the same to me....are they?

Technically a disc bead would also be a rondelle

An online definition of rondel: Jewelry. a flat bead, often of rock crystal or onyx, used in a necklace as a spacer between contrasting stones.

My take is that all donut beads would be rondels, but not all rondels would be donuts.
Rondels would include disk beads and narrow beads that tapered to a point along the outer edge. You would not call these two types donuts.

This is a highly detailed list of bead shapes. From the definition used here and generally in the jewelry/bead industry, what lampworkers call a donut bead is not a donut bead. From this list, it would be considered a rondel or a rotund bead.

LOL Floor, they also call nuggets "Baroques" on that list and the "donuts" look like big hole beads, they say they need a large hole for those.

These are cuts though, and not lampwork. Love to see a chart for the shapes we use. That's one thing I don't recall ever seeing.

You're right, Kristin, that this may seem far from the names a lot of lampworkers use. Don't think the list is exclusively about cut beads, and could still be useful. Guess it depends on if you want to conform to more general names used for the shapes of beads, or you want to stay closer to what lampworkers name their beads. As someone who likes to research beads, I know that many attempts have been made to come to a clear and uniform description of bead shapes. However, it can sometimes become very technical, and not very easy to use. For example, Horace Beck, who was a renowned bead researcher made a full descriptive termology in 1928. He would call the lampwork donut an oblate bead. But what a 'truncated convex bicone' is?

So either way, a list of shapes and terminology used by lampworkers today could be very interesting.
