And clearly when it comes to weddings, she's already done plenty of her own research, and is going to be very 'hands on' as she was with her gorgeous engagement ring.
The Irish influencer shared the stunning sparkler, which she created with her husband-to-be and Paul Conway of Tower Jewellers in Dublin, with her 130K followers, and it's quite a beauty.
"I’m actually the luckiest girl in the whole world, ....I literally cannot take my eyes off it...." Terrie captioned an Instagram video that captured the sparkler in detail, before thanking the designer and apologising for being 'fussy'.
"Thank you so so much to Paul Conway I always knew you would make it with so much love... we love you guys so so much! (ps sorry for being the fussiest girl in the world but you absolutely nailed it."
The couple saw out the special weekend in the luxurious Lyrath Estate, with the bride-to-be sharing a photo of herself wearing her diamond ring in the bath, sipping on a glass of bubbly.
They enjoyed a dinner at the hotel on Sunday night followed by a dip in the pool on Monday morning, before embarking on "a week of serious planning and decision making".
