Qianlong Dynasty? Blue/White Vase

Hello,

I do not have all the dimensions of this vase as it is at my mother's house.  However, I can get them and send a follow-up email with all the information.  Whatever information as to the authenticity and possible value of this piece without the above imformation would be greatly appreciated at this time.  From what I understand, this vase has been in our family for a very long long time.  It is a blue/white porcelain vase with hexigonal top and bottom.  It has a mark on the bottom which looks to be from the Qing Dynasty, Qianlong Period.  It is on a removable carved wooden base.  Exquisite detail.  I can provide better quality photos, as well as, the dimensions if needed.  It is a nice size vase and heavy.  Sorry for the lack of detail here but, I just wanted to get any info available at this time.  Thanks so much for your time and I hope to here from you soon.  Photos are attached.

Thank You,

Donna
