And if you really hate dilution but really want cold drinks, your best bet is an ice sphere.

We’ve probably still got some sitting politely in our freezer maybe enough time has passed for them to be “misplaced.” Just throw them in the garden, replace all your scratched-up tumblers and get on with your life. We’ve all had them clanking around at the bottom of our drink at one point in the past. If you’ve given or received whiskey stones, don’t sweat it. They would have been comfortably at home in the original SkyMall (RIP) along with the life-size ‘Garden Sasquatch’ and other pointless gifts that are destined for the landfill." What to use instead of whiskey stones

"The ones made of stone scratch your glassware, the metal ones clank around your glass like a robot falling down stairs and they just don’t stay cold! Using them is also counterintuitive as whiskey tastes and smells better at room temperature. "Whiskey Stones? Arguably one of the most pointless, ephemeral gimmicks to ever curse the world of spirits," says Ewan Morgan, Head of Whisky Outreach at Diageo. The recent trend of high-ABV bourbons hitting the market comes from bartenders demanding higher proofs that they can dilute with mixers while still maintaining high alcohol content. Half the fun of throwing an ice cube into a drink is to taste the drink change as the ice melts (the other half is that you can throw a cube in your drink without shattering the glass, because it isn’t a whiskey stone). It takes the fun out of drinking, but it illustrates a point: even experts dilute their drink as it “opens up” the whiskey. You sip, you take notes, you add a drop of water, you repeat. If you are a true whiskey snob, you drink your whiskey at room temperature (chilled drinks lessen the effectiveness of your taste buds and olfactory senses) and you drink it with a water dropper. "Arguably one of the most pointless, ephemeral gimmicks to ever curse the world of spirits." (And is also true of reusable ice cubes, which are loads more effective than stones, provided you can bear to watch them float around at the top of your drink like a bad drink umbrella.) This is also sometimes a bad thing. The second claim is that stones prevent dilution. You want to be diluting your whiskey anyway This phase change doesn’t occur with stones. In fact, the process of melting ice absorbs the vast majority of heat in your drink.

Melting ice into water takes a (relatively) incredible amount of heat.

(Or in this case, how much heat that something can absorb from a room-temperature drink.) Ice also benefits from the phase change. Water, and ice to a lesser extent, has extremely high specific heat, which can be thought of as the amount of heat required to raise the temperature of something. Ice is - and has - been the predominant way to cool beverages for centuries, so much so that it seems odd to have to explain why. In regards to the claim that whiskey stones cool your drink: In this arena, the stones, typically made of soapstone to help protect your highball because for some reason you decided to put an actual rock in it, are up against a world-class cooler.
