The Hexagonal Cut — Why This Is Different From Every Other Blue Topaz Earring

The overwhelming majority of blue topaz earrings available today are cut in standard shapes: oval, pear, round, cushion, or emerald cut. The hexagonal cut is a rare geometric form that few cutters execute at this scale — and almost none in fine jewelry. At 12.50 carats per stone, the hexagonal Swiss blue topaz in these earrings presents six flat, symmetrical faceted sides that catch and reflect light from angles that conventional cuts cannot access. The result is a stone that radiates brilliance differently depending on the angle, the lighting, and how it moves — creating a dynamic visual presence that no round or oval topaz can replicate. For the buyer who genuinely wants something that does not exist anywhere else at this quality level, the hexagonal cut is the answer.

Stone Details — Swiss Blue Topaz, Blue Diamonds & White Diamonds

Swiss blue topaz is prized for its vivid, electric sky-blue color — brighter and more saturated than the paler sky blue variety, and distinctly lighter and livelier than the deep inky navy of London Blue topaz. It ranks 8 on the Mohs hardness scale, harder than most gemstones, with a high refractive index that gives it exceptional brilliance and clarity. At 12.50 carats in a hexagonal cut, the face-up size of these stones creates genuine visual drama — this is the kind of earring that commands attention from across a room. The 0.20ct blue diamond accents set above the topaz add a rare tonal echo: blue diamonds are among the rarest colored diamond varieties in fine jewelry, their color produced by trace boron within the crystal structure. The 0.15ct white diamonds complete the piece with flashes of pure brilliant-cut sparkle that frame the geometric Swiss blue topaz below. Together, the three stone types create a color composition that ranges from vivid electric blue through deep sapphire-toned diamond to brilliant white — a layered visual story executed in 14kt yellow gold.

What Is Swiss Blue Topaz?

Swiss blue topaz is a variety of blue topaz defined by its vivid, electric sky-blue color — the most saturated and bright of the three primary blue topaz varieties, sitting between the pale sky blue and the deep navy of London Blue. The “Swiss” designation refers specifically to the color grade: a bright, medium-toned blue that is immediately eye-catching and highly saturated without the darkness of London Blue. It ranks 8 on the Mohs hardness scale, offers excellent toughness, and has a high refractive index that produces strong brilliance across its faceted surface. In large, well-cut specimens like this 12.50ct hexagonal example, Swiss blue topaz delivers the kind of vivid color presence that is typically only associated with much more expensive stones like aquamarine or sapphire — making it a serious collector’s stone when found at this quality and scale.
