Whoa! Compare these stones to those pressed "block" settings that are so prolific elsewhere. Big difference, huh? The pressed-block 'turquoise' is actually shavings, chips and dust created when cutting-down the real turquoise stones. These particles are then put through a machine that further pulverizes them; a resin 'binder' is then introduced and the mixture is compressed into a block about the size of a bar of soap. We're embarrassed for the people who unknowingly buy these and think they have the real thing. Anyway, this piece ships with an 18-inch solid Sterling silver chain. Weight without the chain is 1.15-ounces and the dimensions (not counting the bale) are 2.25 by 2.0 inches. Be proud of what you wear.
