Hand-carved green serpentine cabochon, in two sizes: no.1 (22 × 11 × 5 mm) and no.2 (12 × 7 × 4 mm). Emerald green to bottle green with natural white or black veins. Serpentine's hardness (2.5–5.5 Mohs) makes it ideal for pendants and earrings with a protective setting; we recommend a bezel setting in all cases.

This specific piece
The color of this serpentine is a deep green with lighter-toned veins running diagonally, adding visual movement to the surface. The finish is intermediate between waxy and brilliant: it doesn't achieve the mirror-like polish of quartz, but it has enough reflectivity for the green to appear highly saturated. The visual texture is reminiscent of reptile skin, which is a direct reference to the mineral's name (from Latin serpentinus, "of a serpent").
The lapidary decision for size no.1 was an elongated shape that follows the main direction of the veins, accentuating visual movement. In no.2, the smaller size allows for exploration of color density in a compact area.
What is serpentine
Serpentine is not a single mineral but a group of magnesian phyllosilicates that form primarily through the metamorphism of ultramafic rocks (rich in magnesium) in the presence of water. The process is called serpentinization: olivine and pyroxene in mantle rocks transform into serpentine when reacting with aqueous fluids at moderate temperatures. The most common varieties are antigorite, lizardite, and chrysotile; in lapidary practice, "serpentine" refers to the massive green material of any of these varieties. The variability in hardness (2.5–5.5 Mohs) reflects the diversity of composition within the group.
For what settings does it work
-
Pendants with closed bezel setting (sterling silver) — The most recommended option for this mineral. The bezel protects the edges and prevents abrasion of a stone with lower hardness than quartz. In sterling silver, the green of serpentine gains depth by contrast.
-
Earrings with protected mounting — Possible for earrings where the stone is not exposed to impacts. Not recommended for daily wear rings due to low hardness.
-
Wire wrap — Feasible in formats where the wire rests on the edges and does not scratch the surface. Copper or brass complement the earthy green of serpentine.
Serpentine in lapidary tradition
Serpentine has been carved into decorative and ritual objects since antiquity in multiple cultures: the Aztecs used it in sculptures and ceremonial masks alongside jade; in China it was used for centuries as a substitute for nephrite and jade in imperial jade objects; in medieval Europe it was used in decorative arts, especially in Italy, where green serpentine from the Alps was called "verde antico" and appears in columns and basilica coverings.
In crystal traditions, serpentine is associated with a connection to the earth and practical wisdom derived from direct experience with nature. Its deep green hue and origin in mantle rocks are interpreted as references to permanence and geological depth.
The symbolic properties attributed to minerals belong to cultural and historical traditions. They are shared for educational purposes, not as medical advice.
How to recognize genuine serpentine
Genuine serpentine has a characteristic waxy or resinous luster, distinct from the vitreous luster of quartz or chalcedony. The green is not uniform: there are tonal variations and lighter or darker veins within the same piece. A plastic or resin imitation will show perfect color uniformity and an artificial luster. Serpentine has a noticeable density in hand (greater than plastic). Under magnification, the texture of the polished surface is smooth with no visible individual crystals.
Frequently asked questions
Why is the hardness so variable (2.5–5.5 Mohs)?
The serpentine group includes several mineral species with different hardness. Massive lapidary material typically falls within the 3–5 Mohs range. This variability is intrinsic to the group; it does not indicate treatment or anomaly in the stone.
Is it suitable for rings?
Not recommended for everyday rings without full protection. With hardness lower than quartz and steel (6.5 Mohs), it scratches easily with daily use. For pendants and earrings with a bezel, it works without issue.
Does it have color treatment?
No detectable treatment. The green is natural, originating from iron and magnesium content in the mineral structure. Statement based on lapidary observation; no formal gemological certification.
What differentiates serpentine from jade?
Jade is primarily nephrite (amphibole) or jadeite (pyroxene), with a hardness of 6–7 Mohs. Serpentine is softer and has a distinct waxy luster. Historically, it has served as a jade substitute due to its similar color, but its physical properties are different.
Are the dimensions exact?
With a tolerance of ±0.5 mm on any axis. The freeform shape implies that the perimeter is not a regular ellipse.
How is serpentine cared for?
Clean with a soft, slightly damp cloth. Avoid acids (lemon, vinegar) which attack phyllosilicates. Store separately from harder materials. More information in our jewelry care guide.
