No marking that I can find, It is my thought that it may be cut by Hawkes - the heavy crystal stands 12" high with a 4.5" diameter base - no chips or cracks it does have a tiny tiny flea bite to side - (see pictures). Possibly Pairpoint, Hawkes, American Brilliant or Dorflinger cut crystal vase. The vase has a beautiful ring to it when you flick the top of the vase.
The wealthy estate that this beautiful vase came from also had lots of Hawkes signed pieces. This is a stunning quality antique trumpet vase from a very wealthy estate sale!
