Macroscopic Characteristics of Minerals Part 1: Luster and Color

Now that we know what minerals are, how can we identify them? Geologists use a number of properties of minerals to figure out which mineral they are looking at. The first two we will examine are luster and color. Let's get a closer look!

That was genuinely a treat to watch !. We're so lucky that you're the only one to deal with such amazing and forgotten topics. A side note also that this topics are never easy to explain especially in a brief video but fortunately for us you give a new definition for excellency.

[twomist]

[aaroncoffman]

Thank you for covering this material! Mineralogy can be a difficult topic for undergrads.

[sugarfrosted]

Technically all corundum that aren't rubies are called sapphire, doesn't require they be blue.

Professor Dave: Can you comment on opal? It's my birthstone (October) and I've never been in a position to conduct the tests you're describing here on opal. I'd assume that opal is some kind of hydrated silica based on its outward appearance, but opals I've seen come in many different colors and degrees of translucency. Does this mean that different opals pick up different trace metals to produce different colors? Thanks again for these informative videos!

Cool and thanks Dave.
Color scales and mapping might he a cool topic, talk some pantone maybe? Flat verse gloss? Four bit colors were a big thing.
