Rubies is a new, intimate collection of stunning minerals, gemstones, and jewelry on display in the Earth & Planetary Sciences Gallery.

Ruby, the red variety of the mineral corundum, owes its vibrant color to trace amounts of chromium in its crystal structure. This element also gives many rubies a striking fluorescence, glowing bright crimson under ultraviolet light. Ruby’s internal world—its inclusions, growth zoning, and rutile “silk” needles—records its geological journey and can reveal its origin, making ruby a gemstone of extraordinary beauty and a rich source of scientific insight.
