Jewelry help

Hi all I am getting down to the wire.. my fiance and I are getting married June 1,2024 at 4pm. It's going to be a small family only affair (10-20 people max) ceremony and reception will be at my FIL home in their beautifully landscaped yard ( moving indoors to in front of fireplace if it rains). What I need help with is jewelry! Not sure what way I want to go theme is romance ( I will include a photo of my dress and makeup/ hair inspo photos for reference). The photo of my gown I am wearing a very special necklace I want to wear it however,I'm not sure it's right for the dress. ( It has some of the cremains of my heart dog that passed away suddenly at the age of 4 ( doberman)on Christmas Eve 2023. He was very special to me I have still not gotten over it he was also supposed to be our ring bearer 😞😢. I actually have 2 questions one is knowing how special he was to me any idea of how I can incorporate it into the ceremony without wearing it? Second question, what are your opinions on the jewelry I should wear with my gown. TIA. Sorry so long.. here are pictures. The hair piece will actually be a sequin/pearl comb not flowers.much like this one with sequin comb.
