Natural Star Ruby Rough

Star Ruby Rough refers to uncut or unpolished natural ruby gemstones that display a six-rayed star-like pattern called asterism when viewed under certain lighting conditions. These gemstones are prized for their deep red color and their unique optical phenomenon, which is caused by tiny needle-like inclusions of rutile within the crystal structure of the ruby. Star Ruby Rough is often used for lapidary purposes to create polished cabochons or faceted gemstones with a star effect.
