Sesame Jasper

Sesame Jasper is a trade name for a pale, finely speckled stone whose scattered dark flecks resemble sesame seeds. It is closely related to Kiwi Jasper and the two names are often used interchangeably, with Sesame typically describing finer, more delicate speckling on a cream, grey, or soft-green background.

Like Kiwi Jasper, it is generally a quartz-feldspar aggregate with dark mineral inclusions rather than a true iron-stained jasper. The subtle, evenly distributed speckling gives it a clean, neutral look that suits minimalist jewelry.

It is opaque, takes a smooth polish, and is valued chiefly for its understated speckled appearance.

Sesame Jasper forms as an aggregate where microcrystalline quartz and feldspar (often amazonite) crystallize together with fine inclusions of dark minerals such as tourmaline or magnetite that create the seed-like spots.

The pale background reflects the quartz and feldspar content, while the dark flecks are scattered accessory minerals. As a trade-named material defined by its look, it is sourced from several quartz-feldspar deposits rather than a single jasper quarry.

Identify Sesame Jasper by a pale cream, grey, or light-green body with fine, evenly scattered dark specks resembling sesame seeds. Hardness is about 6-7; streak is white; polished luster is glassy to slightly granular.

Its fine speckling distinguishes it from the coarser, larger spots of Kiwi Jasper or the bold black-on-white of Dalmatian Stone. It is fully opaque. Watch for dyed material if colors look unnaturally vivid.

Sesame Jasper is used mainly for beads, bracelets, and tumbled stones, valued for its subtle, neutral speckled look that pairs well with many designs. It is inexpensive and easy to find.

Metaphysically it is marketed as a calming, grounding stone. Practically, its value lies in its quiet decorative appeal and durability as an affordable lapidary material.
