How safe is this setting?

[KittyBling]

I really like this setting especially the profile but I'm kinda worried the setting might not be 'safe' because there is nothing around the diamond, just the 4 prongs. Other thin 4 prong settings that I've seen all seem to have some kind of metal wire around the diamond (e.g the Leon Mege solitaire). Can any experts pls chime in and let me know what you all think?

Btw this setting will be for a 0.75- 1ct diamond.

Thank you!
