rutilated topaz

Topaz with yellow needle-like inclusions of the mineral Limonite. Rutile Topaz is very similar in appearance to Rutilated Quartz, hence the name Rutile Topaz. However, the name is a misnomer, since unlike Rutilated Quartz which has inclusions of the mineral Rutile, the inclusions of Rutile Topaz are not Rutile but rather Limonite.
