Yes.
Thanks for sharing but I don't see it on wiki. I go to game play: Gear: Accessories and after that there are no more menus. On that page, all I see is this:

Enhancing accessories increases their HP and ATK stats. Using another Accessory of the same element will increase its EXP provision by 50%.

Rarity Different Element Same Element
N 50 75
R 100 150
SR 200 300
SSR 400 600
