On January 31, 2018, Kate wore these earrings in Sweden.
They’re quite large and somewhat casual (in design) for Kate, especially given that she’s taken to wearing more royal jewels in recent years. The earrings consist of a large teardrop pendant made of 14ct white gold and set with a single, uniform row of white diamonds. They are affixed to white gold leverbacks, the front facing sides lined with white diamonds.
On January 31, 2018, Kate wore these natural pearl and gold earrings in Sweden.
These are natural, baroque pearls. They have that irregular, imperfect shape. Because natural pearls are unrefined, each one is unique and holds a different shape. They are drop pearls, dangling from a fish hook. These are set in yellow gold.
On February 18, 2018, we received confirmation that Kate’s statement emerald pendant earrings and bracelet are a part of a suite of jewels.
She wore this opulent necklace to the BAFTAs.
The necklace is made of white diamonds, yellow diamonds, and four prominent emerald stones, arranged in an almost circle at the center of the necklace and as a pendulum drop below the center. I suspect this piece is set in either platinum or white gold.
