One company, two names
Blue Diamond and GreenPan both come from The Cookware Company, and Blue Diamond’s warranty calls its coating Thermolon, the name GreenPan uses for its ceramic nonstick. A lot is shared: both sets go in the oven and under the broiler to 600°F, both sets of glass lids stop at 425°F, both allow metal utensils and the dishwasher while recommending hand washing, and both cover the coating for two years inside a limited lifetime warranty.
Your stove decides
Blue Diamond’s Classic pans work on gas, electric and glass tops but not on induction. GreenPan’s Valencia Pro works on every stove, induction included. If you cook on induction, or might move to it, that settles the sets; Blue Diamond’s answer on induction is its Diamond Bond and Triple Steel pieces, sold one by one.
What each set holds
The Blue Diamond Classic 10-piece is five pans, three lids and two nylon utensils: 7- and 9.5-inch frying pans, a 2-quart saucepan, a 2.5-quart sauté pan and a 5-quart stockpot. GreenPan’s Valencia Pro 11-piece is seven pans and four lids: 8-, 9.5- and 11-inch frying pans, 1.5- and 3-quart saucepans, a 3-quart sauté pan and a 5-quart stockpot, with three pan protectors on top.
Neither set has a pot over 5 quarts, and only the GreenPan has a frying pan over 9.5 inches.
Which one to buy
Choose GreenPan Valencia Pro for induction, two more pans and an 11-inch frying pan. Choose Blue Diamond Classic if you cook on gas or electric and want a smaller set; it adds two nylon utensils. Blue Diamond says its pans are made in its own factories in China; GreenPan’s set page doesn’t say where the set is made.
