I soooooooo wanted to go there!!!!!!
Was too chicken
Also many gems don’t retain their luster, as they’re softer and can be prone to losing their polish. Diamonds are best at retaining their luster due to hardness.
I don’t follow - I’m not saying avoid “luster”? Or at least that’s not what I’m trying to say... The term “luster” is used to describe all the effects outlined in that article and more. But it’s used very inconsistently - different people use it to mean different subsets of all of those effects… But different people also value different subsets of those effects more highly, and currently there’s no common language for buyer and seller to explicate which properties of “luster” are desired/present…
I'm saying, no one would buy Pearls if they did not have luster. Not saying you meant, "avoid luster.”
Luster is what makes Pearls attractive and coveted. If they did not have luster, no one would buy them. Same goes for cut gemstones. You would not have the dispersion & brilliance of a stone that was not polished to show off the luster. One is interlinked with the other but at the same time separate.
The word and meaning of luster are used a lot in the trade. In the trade we know what it means, but it has somehow got discombobulated trickling down to the consumer. This is the trades’ fault, not the consumer. But the consumer can look luster up and know the definition.

I suppose that’s not untrue, when it comes to our gemstones. Huh.lus·ter /ˈləstər/
noun; one who lusts; one inflamed with lust
Did you happen to read the article I linked?
That was written by tradepeople, not consumers - there isn’t universal trade agreement on the definition of the word by any means.
Lustre (mineralogy) - Wikipedia
en.wikipedia.orgPearl lustre is a totally different thing to do with light bouncing off layers of arragonite.What is Gemstone Luster? - International Gem Society
Gemstone luster describes how a gem's surface looks when it reflects light. Learn the common terms used for this property and what affects it.www.gemsociety.org
I'd love to see the definition of luster used by the trade; please cite a source to look up the term.
TIA.
We had been buying aquamarine and morganite from Brazilian and Jaipur cutters, but have shifted to Germans / Idaroberstine simply because of the polish, i.e. better lustre for 30% more money.
