Maison Gripoix, made famous by their collaboration with Chanel, is well known for pioneering poured glass in costume jewelry. It’s just what it sounds like – molten glass placed into a setting rather than a solid prong set stone and requires a high level of craftsmanship.

Bijoux Heart uses the same poured technique glass in this lovely brooch. They designs couture level jewelry that is worth the investment. This piece has matching earrings available for separate purchase. The pin sells for £500; the matching earrings are £550.
