Hi Angela, This is my first translation (!) on italki. Mine is below anyway: "and also, the fact that those details which was meticulously carved is the result of such hard work of a craftsperson." (そして、施された巧みな細工がいかに精魂こめた職人の技であるかということ。) Here, I performed indirect translation, because I believe word-to-word translation tends to lose the flow of a story. So, sorry if you don't understand the definitions of each word.

Here's my try at it. そして、施された巧みな細工がいかに精魂こめた職人の技であるかということ And things like what sort of artisan dedicated how much of his soul into the workmanship applied to the handy work and details. - 施された: put in; given; applied - 巧み: workmanship, craft, skill - 細工: detail work - いかに: how much; to what extent - 精魂: passion/care and soul; earnest and complete dedication - 精魂こめる: put in passion and soul - 精魂こめた: (with) extra passion and soul - 職人: workman; artisan - 技: workmanship; draft; dexterity
