ID Jade plants with purple underside of leaf

Hi,

I am trying to find out if there is a name for my variety of jade plant. I have two, and they are purple on the underside of the leaf, and either green or purplish on the top of the leaf. I have looked at many pictures but all the ones I've seen have been purple/red on the top or edges of the leaves only - I haven't seen any with a purple underside. My plants are young, get moderate sunlight and are currently in winter. The plants were bought in NZ.

I also have attached an image from someone else with a similar plant. They say their plant is healthy and receives a lot of light. They are in the USA so their plant is currently in summer.

Thank you for any help.
