Ocean jasper is a type of orbicular jasper that exhibits striking circular or spherical patterns. These distinctive markings are what set ocean jasper apart from other types of jasper stones. The swirling circular designs resemble the rippling surface of the ocean, which is how ocean jasper got its name.
In terms of color, ocean jasper can display a wide range of hues but is typically characterized by shades of green, gray, pink, red, brown and yellow. The main body color is usually a darker greenish-gray or brown, while the circular orbicules exhibit brighter highlights of pink, red, yellow and white. The contrast between the dark base and the light circular patterns is quite pronounced.
The signature orbicular patterns found on ocean jasper can vary greatly. Some pieces feature dozens of small uniform circles in concentric formations that look like tiny ripples radiating outwards. Other patterns are more abstract, with larger swirling circular designs spaced further apart. The shapes of the individual orbicules can be almost perfectly round or more oblong and elliptical.
In some specimens, the circular patterns appear to have multiple rings, much like the cross section of a tree trunk. This gives the impression of concentric layers within each orbicule. Other pieces have orbs filled with various internal crackling or dot patterns. The designs are endlessly unique and no two ocean jasper stones ever look exactly the same.
In addition to the distinctive circular patterning, ocean jasper often displays interesting textural qualities like botryoidal masses and druzy formations. The surface may have small round nodules that resemble bunches of grapes. Druzy patches exhibit tiny sparkling crystals that form crusty coatings over parts of the stone. These textural elements add visual depth and interest.
While green is the most common base color, some ocean jasper has a reddish-brown, yellowish-gray or blackish background. Pieces with a very dark base tend to make the lighter circular patterns stand out more dramatically. Other stones may be mottled with additional spots, veining or streaks of contrasting colors. There is a great deal of diversity when it comes to the color combinations seen on ocean jasper.
Most ocean jasper exhibits a natural smooth polish but some pieces can have a waxier, satiny finish. The appearance can range from glassy with high clarity to more opaque with inclusions that limit light transmission. A polished cabochon cut is ideal for maximizing the optical effects of the swirling orbicular patterns. The rounded shape also calls to mind a floating world globe.
So, the distinctive look of ocean jasper stems from its signature circular patterning in shades of green, pink, red, yellow and white, overtop a darker colored base. The designs evoke visions of rippling waters and waves radiating outwards. Combined with textural elements and color variations, ocean jasper has a very fluid, aquatic visual quality unlike any other stone. The diverse patterns and colors reflect the beauty and mystery of the seas.
