4.50ct Blue Colorado Topaz

The United States’ diverse and dramatic landscapes, ranging from the soaring peaks of the Rockies to the sunbaked deserts of the Southwest and the ancient, forested hills of Appalachia, cradle a treasure trove of exceptional precious gemstones.

From the iconic sapphire mines of Montana to the rugged terrain of California and the desert plains of Utah, North America yields a vibrant spectrum of gems. The famed sapphires of Montana are prized for their natural moody blues and teal hues. Tourmaline from California delights in hot pinks and verdant greens, while Oregon’s sunstone, glittering with copper inclusions, is unlike any other. Utah offers topaz, Colorado brings forth Rhodochrosite, and North Carolina produces hiddenite, a rare green variety of spodumene. In the Appalachian foothills, rubies, sapphires, and emeralds have been found in their natural splendour.

USA mining regulations are governed mainly at the state level, with oversight from federal agencies like the Bureau of Land Management. In recent years, there has been an emphasis on ethical sourcing, environmental stewardship, and partnerships with Indigenous communities to ensure that the extraction of these precious gems honours the land from which they come.
