2 Diamond Quilted Trapped-Air MOP Tumblers

This pink one is attributed to Thomas Webb; it is without signature or applied design. The upper rim is ground, an' chamfered inside & out; the bottom has a central ground pontil, ~5/8" diameter. Rim diameter is ~2 7/8", height is ~3 7/8", weight is ~7 oz. The upper 1/3 is very slightly flared. It is, as far as I can determine, without damage or flaw.

This blue one may be Mt. Washington, or perhaps Murano. There are several subtle but significant differences between this an' the pink ~Webb: The borders of the diamond pattern are perhaps twice as wide as the pinks, an' those diamonds appear 'deeper'; The upper rim has been a bit unevenly sheared (it rocks slightly) then flame polished; The ground pontil is ~7/8" diameter an' has a small fracture remnant in the center; This tumbler is also heavier, at ~9 1/8 oz; An' of course there's the enamel bird in flight with nesting material. Rim diameter is ~2 13/16", height is ~3 3/4".
These two came from the estate of the widower (now in memory care) whose wife was an avid collector an' jewelry designer. Neither of them are UV reactive.
Your comments an suggestions are eagerly sought, an' much appreciated...Thanks for lookin'!
