    History, Types, Cultural Significance Of cushion cut tanzanite engagement rings

    The cushion cut—known for its soft edges and pillow-like shape—has been adored in engagement jewellery for centuries. When paired with tanzanite, one of the world’s rarest gemstones, the result is a ring that radiates sophistication, warmth, and individuality.

    Our Cushion Cut Tanzanite Engagement Ring collection features:
    – Solitaire cushion tanzanite rings with clean, minimalist bands
    – Diamond halo designs for vintage sparkle
    – Three-stone rings for symbolic storytelling
    – Art Deco-inspired settings with intricate detail

    Tanzanite is the birthstone for December and is prized for its unique trichroic effect—shifting between blue, violet, and burgundy hues in different light. In UK jewellery, cushion-cut tanzanite engagement rings are popular among those seeking a non-traditional engagement ring that still feels timeless and elegant.

    These rings offer a perfect balance between softness and boldness, heritage and individuality.
