Colors
Jade (Jadeite) is found in green (incl. imperial), lavender, white, yellow, black. The body color, its saturation, and how evenly it spreads through the stone are among the strongest drivers of value.
How to tell real from imitation
No single test settles it, but a few grounded checks quickly narrow things down for Jade (Jadeite). Hardness, brilliance, and the list of stones it is commonly confused with all give you something concrete to look for.
- Scratch resistance: genuine Jade (Jadeite) sits at Mohs 6.5–7, so it should resist scratching from softer materials — a stone that mars far too easily is suspect.
- Brilliance & luster: Jade (Jadeite) shows a vitreous to greasy luster and a refractive index of 1.652–1.688; imitations often look glassier or flatter under the same light.
- Density: a real Jade (Jadeite) has a specific gravity near 3.3–3.38, so it feels heavier or lighter in the hand than many look-alikes of the same size.
- Commonly imitated by: nephrite jade, serpentine, dyed quartz. If a deal looks too good, suspect one of these substitutes first.
- Fast first read: photograph the stone in the Jewelry Identifier app to estimate the gemstone and its likely value range, then confirm anything important with a gemological lab.
Common treatments
- impregnation (Type B, C, B+C)
- dye
Treatments are routine for many Jade (Jadeite) stones, but they materially affect value and should always be disclosed — an untreated, lab-certified stone commands a clear premium over a treated one.

FAQ
- Q. Is Jade (Jadeite) hard enough for everyday rings?
- A. Not ideally. At a Mohs hardness of 6.5–7, Jade (Jadeite) is soft enough to scratch with everyday wear, so it is better suited to earrings, pendants, or occasional-wear rings with protective settings.
- Q. How can I tell Jade (Jadeite) from nephrite jade?
- A. Jade (Jadeite) and nephrite jade can look alike to the naked eye, but they differ in measurable properties — refractive index (1.652–1.688 for Jade (Jadeite)), specific gravity (3.3–3.38), and hardness (Mohs 6.5–7). A gemologist confirms the distinction with a refractometer and loupe; the Jewelry Identifier app gives a fast first read from a photo.
- Q. Does Jade (Jadeite) come in colors other than green (incl. imperial)?
- A. Yes. Jade (Jadeite) occurs in green (incl. imperial), lavender, white, yellow, black. Color is driven by trace elements and treatment history, and it is one of the biggest factors in a stone's value.
