1. Many of them belong to the "bimpu family". Bimpu is a generic term for medium-sized glass beads, especially those that make up bimpu tasan, a necklace composed of as many as 20 types of beads displayed on a dozen or so strands. The shapes vary from cylindrical to roundish. They are differentiated mainly on the basis of their hues:
- lanchan bimpu : red slightly translucent glass bead
- ji bimpu : dark blue slightly translucent glass bead.
- jiji bimpu : green slightly translucent glass bead
- horpu bimpu : translucent glass bead
- bimpu ami is a special type of glass beads originating from Venice circa 19th century. Black or burgundy in colour with white dots, they are commonly known as "Skunk beads". The Taniis simply call them bimpu ami or "eyed bimpus".
2. Tado are small, cylindrical opaque yellow beads used to make necklaces known as tado tasan. Two shades are distinguished, each used to make up a specific necklace simply consisting of several strands of these beads.
- akho tado : bright yellow
- aper tado : terracotta

3. pike tasan is a translucent glass bead of amber hue.
4. nyime perun (or peron), literally "Tibetan soja bean" is a small, cylindrical dark blue bead. As the name indicates, they seem originate from Tibet, or more probably, as Fürer-Haimendorf suggests, they were probably obtained from Tibet on a regular basis till the Chinese takeover. As he writes in 1962 :
"Most women possess strings of crudely cut cylindrical glass beads of dark blue clour and it could seem that these have also come from Tibet. They are quite different from any beads manufactured or known in India today (...) Today they are no longer popular, and have indeed very little market value. Their place has been taken by smaller and smoother glass beads of similar dark blue colour which have for some years been available in the bazaars of North Lakhimpur." (1962, 68).
Nyime perun are used to make necklaces known as nyime tasan or ji tasan, consisting of several strands of those dark blue beads ornamented with yellow and red beads.
5. Lebu ralin, despite its name, is not a carnelian bead but simply a glass bright red bead which is set up at intervals to decorate nyime tasan necklaces.
