About Star Cluster Topaz
Star Cluster Topaz from SK Star #1 Claim in the Topaz Mountains of Utah is a show-stopping variety of topaz, famous for forming in volcanic rhyolite where fluorine-rich gases and hot fluids helped topaz crystallize in open pockets and fractures. What makes the “star cluster” pieces special is the way multiple sharp, glassy crystals radiate from a shared core, creating a natural burst or rosette that looks almost engineered. The crystals are typically colorless to champagne (sometimes with faint sherry or smoky tones), with high clarity, crisp terminations, and that distinctive bright, vitreous luster topaz is known for.
Because these clusters grow in tight cavities, it’s common to see inter-grown, symmetrical points, occasional etched faces, and a bit of attached rhyolite matrix that highlights the geology and proves the piece is exactly what it claims to be; wild Utah topaz in its native rock. Each cluster is inherently one-of-a-kind: some have a compact “star” with stubby rays, while others spread into more open, spiky sprays. Whether you’re collecting for aesthetics, locality, or classic Great Basin mineral history, SK Star #1 star clusters capture the best of Utah topaz—clean, flashy crystals arranged in a naturally dramatic formation.
The SK Star #1 Claim is recognized as part of a site that is potentially the only location on Earth consistently producing black topaz alongside these star clusters. The site consists of a trench dug along a fault line within the Topaz Mountain Rhyolites. The black coloration in the topaz is consistent throughout the samples found there. Beyond black topaz, the claim has yielded rare metal oxides like wolframite and pseudobrookite, as well as "ram's horn" calcite and rare native gold.
