Authentic

Authentic specimen

Natural Hetian seed jade, formed by long-term river erosion, with natural pores and skin color

Fine natural pores, varying sizes
Natural skin color transition, uneven depth
Warm, delicate texture with strong oily feel
Solid feel, high density
Subtle, restrained luster

Fake/Treated

Fake specimen

Machine-tumbled mountain jade, simulating seed jade shape, then dyed to add skin

Overly uniform pores, mechanical appearance
Surface-level skin color, overly vivid
Visible polishing marks on edges

Common forgery methods:

1.Tumbler polishing to simulate water erosion
2.Chemical dyeing for fake skin
3.Acid etching for fake pores

Practical Identification Tips

1

Use 10x magnifier to check pores - natural ones vary in size and distribution

2

Use flashlight - authentic shows soft even light, fake may show pigment deposits

3

Scratch skin color with fingernail - fake skin easily loses color

4

Water drop test: water beads up on authentic seed jade
