- Toi et Moi or trilogy designs: Pair a heart blue centre with white diamond side stones to create a striking contrast – symbolising "two hearts, one journey."
- Anniversary pendants & "promise" jewellery: A blue heart diamond suspended as a pendant rests close to the wearer's heart, making it a poignant gift for milestone anniversaries, Valentine's Day, or celebrating a new beginning.
