Whether or not expensive investment dinnerware is worth it for you will depend on your lifestyle. If you like luxury, and frequently host, then an expensive artisanal set may be worth investing in to show off to guests. If you rarely host and use dinnerware more casually, then it may not be worth the risk of accidentally dropping and breaking it when washing up.
Ultimately, a good set of dinnerware can elevate a meal, making it look and feel more special, but this can often be done no matter the price of your dinnerware if you spruce up your serving skills – the choice is a very personal one.
