Director's Notes

Yellow sapphires have long been valued for their warm, radiant hues, ranging from rich golden tones to soft, lemony shades, with unheated stones considered especially desirable and rare.

In the 1970s, gold jewellery surged in popularity and jewellery from this era is known for its sculptural forms, organic textures, and statement designs, reflecting a confident and expressive aesthetic.
