The average weight of a gem/jewelery/art.

I'd appreciate any info about official rules, rules-of-thumb, or even educated guesses as to the average weight of...

...a single gem.

...one piece of jewelery.

...one art object.

Thanks in advance!

That's way too much though.....5 gold or platinum coins weighs 1/10th of a pound in D&D. Gold and platinum are rather heavy elements. 5 coins is not going to be the same weight as a tiny piece of jewelry, like a ring or earring, or a precious stone/gem.

In general, just don't worry about it. Maybe assume that precious stones and gems are something like half the weight of a coin, if you need to guess (even though some will be heavier and some may be lighter). Jewelry, just mentally picture it alongside a stack of coins and guesstimate how many coins would be roughly the same size, and use that as a rough estimate of weight.

Like, maybe a typical expensive necklace would weight 1 pound or so, while a cheap one might weigh 1/10th or 1/5th of a pound from having only one precious stone on it and no metal chain. With a metal chain, it might be 1 pound or so, I dunno.

For bigger jewelry and art, just guesstimate based on a similarly-sized item. A big painting? Well, maybe it's the same weight as a few yards of canvas, since it's got a wooden frame and such too. A statuette or bust the size of your head? Maybe it's the same weight as a battleaxe or a spool of rope or a full jug of ale. A golden crown studded with gems and precious stones? Maybe it's the same weight as a battleaxe too, since gold is heavy.
 

A single 1 carat gem weights 1/2000th of a pound. Effectively negligible. A round gem, 20mm diameter, give or take, weights about 1/50th of a pound. That being the standard fantasy size for gems.
