About the Chapter 123 Trilogy Collection

Chapter 123 is a small collection of seven diamond pieces in 9ct and 18ct yellow gold. Its trilogy theme refers to three moments: the past that shaped us, the present we hold dear and the future still to be written. This idea appears through three-stone arrangements and repeating groups of three diamonds.

The collection includes two rings, two necklaces, a bangle, a bracelet and a pair of earrings. Prices below were checked on 21 September 2026 and may change. Confirm the latest price, sizing, diamond specifications and availability before purchasing.

The seven Chapter 123 designs

18ct Yellow Gold Round & Pear Cut 1.23ctw Diamond Ring — $6,999

This ring combines a round brilliant centre diamond with pear-cut side stones. The mixed shapes give the trilogy setting a more defined centre and a broader outline than a design using three matching round diamonds.

9ct Yellow Gold Round Cut 3.00ctw Diamond Necklace — $7,499

The larger of the collection’s two necklaces has a listed total diamond weight of 3.00 carats. Its three-stone arrangement makes the trilogy theme particularly visible.

9ct Yellow Gold Round Cut 1.20ctw Diamond Ring — $3,999

This version uses round-cut diamonds in 9ct yellow gold. Its matching diamond shapes create a more uniform appearance than the mixed-cut 18ct ring.

9ct Yellow Gold Round Cut 1.00ctw Diamond Bangle — $4,499

The bangle has a structured yellow-gold form with diamond detail positioned at the centre. Check the listed dimensions carefully, as bangle fit depends on both wrist and hand measurements.

9ct Yellow Gold Round Cut 2.00ctw Diamond Bracelet — $4,999

This flexible bracelet has a listed total diamond weight of 2.00 carats. Round-cut diamonds are arranged in repeated trilogy groups around the bracelet.

9ct Yellow Gold Round Cut 0.50ctw Diamond Necklace — $1,999

The smaller necklace has a listed total diamond weight of 0.50 carats and a simpler scale than the 3.00ctw design. Confirm the current chain length and pendant measurements when considering fit.

9ct Yellow Gold Round Cut 0.50ctw Diamond Earrings — $1,499

These yellow-gold huggie earrings have a listed total diamond weight of 0.50 carats. Their compact format makes them different in scale and wear from the larger necklaces, bracelet and rings in the collection.
