Not quite ....a ground sweet mix of almond or hazelnut.
"Praliné noisette 70%" means: a chocolat (bonbon) - 70% pure chocolate - mixed with a "pralin" of hazelnut.
The powder made by grinding up such caramel-coated nuts is called pralin, and is an ingredient in many cakes, pastries, and ice creams. After this powder has been mixed with chocolate, it becomes praliné in French, which gave birth to what is known in French as chocolat praliné. The word praliné is used colloquially in France and Switzerland to refer to these, known simply as "chocolates" in English, i.e. various centres coated with chocolate.
