The 19-year-old was last seen during the early afternoon of Wednesday 28 November 2018 in the Leachkin area of the city.
Extensive efforts have been ongoing to locate her but so far these have been without success.
Jade, who is from the Aviemore area, is considered to be vulnerable and officers are keen to ensure her safety as soon as possible.
Inspector James Rice said:
"Jade has not been seen since Wednesday afternoon and as time passes her family are naturally growing increasingly concerned for her."
"We have been carrying out thorough enquiries to piece together Jade's movements since she was last seen."
"So far we do not have a confirmed sighting since she was seen in the Leachkin Road area so I would urge residents who live around that part of the city to be vigilant."
"Please thoroughly check any sheds or outbuildings in case Jade has sought shelter and report any information you feel could be of assistance to us as soon as you can."
"It is also possible that Jade could have travelled away from the area so I would urge everyone to be vigilant and get in touch if you believe you have information which could help."
"If Jade herself is reading this then please let us know you are okay. You are not in any trouble and your family just want to make sure you are safe."
When last seen she was wearing a light grey turtle neck top, parka jacket, black leggings and black/white coloured Nike trainers.
Anyone with information which could help locate Jade is asked to call 101, quoting reference NN12175/18
