You may be too grown up to get a ruler for back to school, but don’t count the measuring tool out this fall. Jewelry line Digby + Iona
chose the ruler as inspiration for their “Means of Measurement” collection, in which many of the pieces are engraved with a classic Galileo quote: “Measure what is measurable, make measurable what is not.”
The sterling silver Slide Caliper Necklace
($220) is a miniature and fully functioning ruler with a movable slide.
