Our collection of large gemstones includes impressive natural stones sourced from trusted deposits around the world. These oversized gems showcase exceptional color, clarity, and presence, making them ideal for statement jewelry or gemstone collections.

Large loose gemstones for statement jewelry and collectors

Collector Size Gemstones

Large gemstones are highly desirable among collectors who appreciate rare sizes and impressive specimens. Oversized stones highlight the natural beauty of gems and often display stronger color zoning, clarity, and crystal structure.

Faceted Large Gemstones

Faceted large gemstones maximize brilliance and sparkle. Larger surfaces allow light to interact with more facets, producing exceptional fire and brilliance in stones such as sapphire, amethyst, citrine, garnet, and topaz.

Cabochon Large Gemstones

Cabochon cuts are popular for large gemstones because they emphasize color saturation and natural patterns. This style works especially well with gems like moonstone, labradorite, turquoise, and opal.

Rare Oversized Gemstones

Some gemstones become increasingly rare as size increases. Large sapphire, ruby, spinel, and tourmaline stones are particularly prized because high-quality rough capable of producing oversized gems is uncommon.

Buying Large Gemstones Online

GemSelect makes it easy to buy large gemstones online. Every stone is photographed individually and comes with detailed specifications including weight, size, clarity, and treatment information to help you choose with confidence.

GemSelect offers excellent choices, prices & service- highly recommended! Unfortunately, prior to ordering a replacement gemstone, my jeweler neglected to mention it needed to be one that was a'cushion cuta' to fit the existing mount. Have yet to return/exchangea'
