Gemma "Gem" Reeves is a fictional character from the Australian soap opera Neighbours, played by Kathryn Beck.

Gem was introduced as the cousin of established characters Georgia Brooks (Saskia Hampele) and Toadfish Rebecchi (Ryan Moloney).

Using her position as a biology teacher, Gem sabotaged some of her students, while also encouraging Bailey Turner's (Calen Mackenzie) crush on her.

She has been described as someone "viewers love to hate", a "superbitch" and a "fun whacko", but Gem also been called "one of the soap's most irritating characters".

One critic thought Beck was doing "an excellent job" and the character's appearance and introduction also received positive attention.

In September 2013, the show's then executive producer Richard Jasek teased Gem's introduction, saying established character Georgia Brooks (Saskia Hampele) would have "a relative coming to visit, who's going to cause absolute merry hell for everyone.

[5] Shortly after arriving in town, Gem literally bumps into Kyle Canning (Chris Milligan) and he spills coffee down herself.

[6] Daniel Kilkelly from Digital Spy reported that just as things appear to be going well, it would become clear that Gem is keeping secrets surrounding her past.

[8] Toadie asks Susan Kennedy (Jackie Woodburne) to hire Gem as the new biology teacher at Erinsborough High when the position becomes vacant.

[2] After she is given the job, it emerges that Gem is scarred by a "scandalous" dismissal from her previous school and she assures her mother over the phone that she is ready to return to teaching.

[6] A Soap World columnist wrote "Now that she's comfortably settled into the school and the Rebecchi house, Gem's unable to shield her true personality any longer.

"[6] Showing "a nasty streak", Gem humiliates her student Josie Lamb (Madison Daniel), who is struggling with low self-esteem.

[6] Gem then turns her attention to Imogen Willis (Ariel Kaplan) and her intention to run for school captain.

Gem becomes annoyed by Imogen's confidence and manipulates her friend Amber Turner (Jenna Rosenow) into standing against her.

[6] "I thought how would Georgia not see all of this manipulation that's going on with Gemma, but Kathryn was just so incredibly talented and managed to convince me that there was nothing bad going on in the background.

[10] An "uneasy chemistry" develops between the pair and Mackenzie stated that Gem makes Bailey believe that they could be more than just friends, calling the storyline not "your usual teacher/student dynamic.

[6] Gem starts to enjoy Bailey's attention and they develop "a firm friendship", which results in Imogen catching them holding hands at Lassiter's Lake.

[12] At the same time, Gem also begins causing trouble between Georgia and Kyle, by encouraging her cousin to apply for an overseas job.

[9] Gem is pleased when Georgia leans on her for support, but becomes "increasingly infuriated" by her inner strength and tries to isolate her, by taking her away to a private cottage.

[7] At the cottage, Gem steals Georgia's phone, cutting her off from the outside world, and tells her the car will not start when she wants to leave.

"[19] Butler also quipped "Gem is the greatest strategist since Kevin Rudd" and said she could not wait to see how things ended between her and Georgia.

[20] Melinda Houston from The Sun-Herald praised both the character and actress, saying "There's something enduringly creepy about the Single White Female and the addition of Gem to Ramsay Street makes a nice variation on the assorted femme fatales and bad boys that are Neighbours usual fodder.

"[22] Gem was also included in TV Week's "screen meanies" feature, where a columnist wrote "Move over, Paul Robinson, Erinsborough has a new baddie!"

[16] The Age's Larissa Dubecki said "Another year, another psycho alert in the Anglo-Saxon enclave of Erinsborough", while also branding Gem "increasingly unstable".

[24] A writer for TV Soap observed that the addition of "superbitch" Gem was another new direction for Neighbours and that she was the first bad girl "viewers love to hate" since Izzy Hoyland (Natalie Bassingthwaighte).

[26] While reviewing the 2014 season opener for the Herald Sun, critic Cameron Adams named the episode as one of his picks of the day.
