Exploring the Meaning of Sardonux in Greek

σαρδόνυξ means “sardonyx” and appears in the description of the New Jerusalem’s foundations. In that setting it functions as one named element in a carefully ordered list of precious stones.

Root and Related Words

σαρδόνυξ (Sardonux) is related to σάρδιον (sardios, “gem”; Strong’s G4556), the word from which it derives.

Occurrences

“the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprase; the eleventh, jacinth; and the twelfth, amethyst.” (Revelation 21:20)

Here σαρδόνυξ is introduced as “the fifth” item in a sequence, placing it within a numbered structure rather than presenting it as an isolated ornament. The verse itself is composed almost entirely of names—each stone is identified, then the next follows—so the word’s contribution is primarily identificatory: it supplies one specific foundation-stone designation within the larger catalogue. By standing alongside “sardius,” “chrysolite,” “beryl,” “topaz,” “chrysoprase,” “jacinth,” and “amethyst,” “sardonyx” participates in an enumerated register of precious materials that portrays the foundations as varied, distinctive, and intentionally arranged.

The immediate syntax also highlights how the list is meant to be read: the semicolons mark a measured progression (“the fifth… the sixth… the seventh…”), giving σαρδόνυξ a fixed place in the series. In such a context, the word does not carry the action of the sentence; it carries the descriptive weight. The effect of naming “sardonyx” is to make the depiction concrete, calling for the reader to imagine a particular kind of gemstone as part of the city’s substructure.

Sense and Usage

The sense “sardonyx” functions here as a precise material designation. Revelation 21:20 does not describe the stone’s color, shape, or setting; it simply names it as one foundation element among twelve. That restraint is itself significant for how the word works: the text leans on the recognized identity of the gemstone name to evoke value and beauty without additional qualifiers. In other words, σαρδόνυξ contributes by being a specific noun in a list whose rhetoric depends on specificity—many distinct stones rather than a single general term for “jewels.”

Because the only attested use is within a structured enumeration, the word’s usage is tightly bound to classification and order: it marks one slot in the foundation sequence (“the fifth”). The juxtaposition with “sardius” immediately following also shows how the passage distinguishes between closely named stones by treating each as a separate item in the series. The verse thereby uses gemstone terminology not as interchangeable ornamentation but as discrete labels that build a layered picture of richness through accumulated particulars.

The relatedness to sardios (“gem”) provides a lexical point of connection within the same semantic field of precious stones. In Revelation 21:20 the reader encounters “sardonyx” and “sardius” adjacent in the list, reinforcing the impression of a curated set of gem-names. Within that naming strategy, σαρδόνυξ serves the broader aim of portraying the city’s foundations as composed of materials worthy of careful naming and careful counting.

Imagery

Placed in the foundations list, “sardonyx” draws attention downward to what supports the city, not merely what decorates its surface. The image is of stability expressed through splendor: foundations that are not hidden rough stone but are articulated as a sequence of named gemstones—“the fifth, sardonyx”—as though the very base of the city is intentionally formed and openly displayed.
