Discover the timeless beauty of round gemstones, one of the most classic and versatile shapes in the world of fine jewelry. From brilliant sapphires and vibrant tourmalines to rare collector stones, our selection of round cut gemstones showcases exceptional color, brilliance and craftsmanship.
At Moriarty's Gem Art, we have spent decades working with fine colored gemstones. Many of the loose gemstones you'll find here have been individually selected and precision cut to bring out the beauty, color and personality of each stone. Rather than treating every gem the same, the cut is chosen to complement the individual piece of rough and create a finished gemstone worthy of fine jewelry.
The round shape remains one of the most popular gemstone cuts for a reason. Its symmetry creates a balanced, elegant appearance while allowing a skilled cutter to maximize light return and brilliance.
A beautifully proportioned round gem can look exceptional from virtually every angle. The shape works particularly well for transparent colored gemstones, where carefully arranged facets help light travel through the stone and return to the eye.
Depending on the gemstone and cutting style, a round stone may feature a traditional faceted pattern, a round brilliant cut, or a custom variation designed specifically for that individual gem.
One of the greatest advantages of a round cut gemstone is its versatility. Round stones work beautifully in nearly every style of fine jewelry, including engagement rings, gemstone rings, pendants, necklaces and earrings.
For a classic look, a larger round gemstone can serve as the centerpiece of a solitaire or halo design. Smaller matching or complementary round gems can also make exceptional earrings or accent stones.
Round gemstones pair beautifully with yellow gold, white gold, rose gold and platinum, allowing the gemstone's color to become the focal point of the finished piece.
Our collection of round cut loose gemstones can include a wide variety of natural gem materials, colors, sizes and cutting styles. Depending on current availability, you may find:
Because natural gemstones are unique, our inventory continually changes as exceptional new stones are sourced and cut.
The round brilliant cut is designed around one primary goal: light performance. A series of precisely positioned facets helps reflect light throughout the gemstone, producing the flashes of brilliance and sparkle associated with this classic cutting style.
While the round brilliant is famously associated with diamonds, the same basic concept can create spectacular results in colored gemstones. The cutter must account for the optical properties, color and shape of the original rough rather than simply applying the same proportions to every stone.
This is particularly important with valuable colored gems, where preserving beautiful color and carat weight must be balanced against brilliance and overall appearance.
A gemstone is only as beautiful as the finished cut allows it to be. Proper proportions, symmetry, polish and facet placement can dramatically affect how a gemstone handles light and displays its color.
The Moriarty family has more than 40 years of experience working with gemstones and fine jewelry. Master gem cutters Steve and Larry Moriarty have cut gemstones from around the world, transforming carefully selected rough into finished gems designed to showcase their natural beauty.
That experience is especially apparent in a symmetrical shape such as a round gemstone, where precision matters.
