Hi,
Lovely dress especially the touch of sparkle I can see. My website is www.lynseysdesigns.co.uk but here are a few examples however I have heaps more designs on the website and also mainly work with bespoke designs so can create something different from what you see.
This necklace is made with large freshwater pearls so is too chunky against your delicate dress but just as an example of rice shaped pearls on an illusion setting
Or this which was designed for Boogiebelle and again uses freshwater pearls and is extremely pretty and elegant (my favourite pearl design).

All jewellery designs can have matching earrings and bracelets.
To compliment your sweetheart neckline a tiara with a gentle point always works well I feel. One similar to this would be lovely but the point doesn't need to be as obvious and I would suggest a slightly softer tip to it.

This is similar but has a more random design to it
.
All tiaras can be adapted to suit using pearls and crystals and changing the height etc.
If I can help at all feel free to email me on lynsey@lynseysdesigns.co.uk.

ETA: It is good to know what your hairstyle will be like as that can play a big factor in what your tiara is like so would be good to chat to you about that if you email me. For example I know I didn't want to have much height to my hairstyle so I have opted for a low tiara that is only 2cm tall and whilst it may be small it is still stands out with the right hairstyle.
