NS-008 Dark Ruby is the most saturated of the transparent striking rubies Northstar produces. It must be worked in a hot oxidizing flame to prevent liveriness. Because it is so intense it can be easily flame struck. It is most useful for small sculptural accents, cane work, and stringers. When fully struck, it can yield a rich opaque Chinese red.
