> Grandma's heirloom Tiffany engagement ring will have meaning in the way that a lab grown no name ring ordered online will not, even if they are completely indistinguishable.

Not sure how to parse that. Perhaps it's a cultural thing? This seems to be conflating value, meaning and worth in a confusing-to-me way.

- "Grandma's heirloom" would have sentimental value, regardless of brand name, production process or monetary value. Grandma's candy box or her modest music box would have similar sentimental value. Depending on what this grandmother meant to you as a person, this could be positive or negative sentimental value.

-"Tiffany's" versus "no name, ordered online" might for equal quality jewelry make for a slight higher resale value. All other things being equal, that is.

- Lab grown versus mined could make a slight difference in resale value. This is very often very much overestimated because of how the diamond retail market works.

- Lab grown versus mined really depends when it comes to emotional value.

  - For example, if someone were to offer my wife or me a mined diamond with no history, we'd assign it negative emotional value because of the suffering attached. Unless it were to have come from a historical source with no money having changed hands, not even in the second hand trade. In which case no extra harm would have been done even by trading in the secondary market.

  - Others might attach positive emotional value to the rarity of the mined diamond.

  - Some sociopaths, psychopaths or sadists no doubt attach positive emotional value to the knowledge people had to suffer for the ring on their finger.
