Fantasy cut rings feature gemstones that are sculpted, not just faceted. Instead of flat geometric facets, each stone is hand-carved with concave grooves and engraved patterns that send light streaming through the gem in radiating ribbons — a technique pioneered by German lapidary Bernd Munsteiner in the 1970s. Because every stone is carved individually, no two fantasy cut rings are ever identical.
Our collection pairs this sculptural cutting style with lab-grown gemstones — alexandrite, sapphire, and other fine crystals grown to jewelry-grade purity — set in recycled solid gold and made to order. Each design can be customized in our Clio 3D platform: choose your metal, prong style, and band profile, and see your ring rendered before it's crafted.
What makes a cut a "fantasy cut"?
A fantasy cut (also called a designer or sculptural cut) uses precision engraving to carve curved, mirror-polished grooves into a gemstone's pavilion. These concave optics behave differently from flat facets: rather than uniform sparkle, light travels through the stone in flowing streaks and starbursts that move as your hand moves. The cutting process sacrifices significant rough crystal — often 40–60% — which is why fantasy cuts are typically reserved for lab-grown material, where clean rough is available in generous sizes.
Which gemstones work best?
Color-shifting and strongly colored gems benefit most, because the carved grooves display several tones at once. Lab-grown alexandrite is the signature choice — its green-to-purple color change appears to swirl inside the carving. Sapphire, in both classic and unusual hues, holds crisp groove definition thanks to its hardness. All stones in this collection are durable enough for daily wear at 8.5–9 on the Mohs scale.
Are fantasy cut rings good engagement rings?
Yes — they're a favorite for couples who want a genuinely one-of-a-kind center stone. The stones are solid crystal (the carving adds no fragility), open settings keep the light show active, and every Giliarto ring is made to order in your size and metal. Because each stone is unique, we photograph and video your exact gem for approval before setting.
Care: warm water, mild soap, and a soft brush keep the grooves brilliant. Annual prong checks, as with any daily-wear ring.
