3.33 ct Diamond Tennis Bracelet, Yellow Gold

3.33 carats of natural round brilliants in 18K yellow gold, 17.5 cm on the wrist.

Yellow gold changes what colour grade means. Only the metal actually touching a diamond reflects back into its pavilion, and in a claw-set row that contact is small — but on a bracelet it is repeated across every stone, so the warmth accumulates along the line in a way it never does on a single ring. That is why this row is specified D to F rather than lower: the colourless band gives the yellow metal something to warm against, instead of compounding a tint the stone already has.

Clarity is VS, so nothing in the row is visible to the unaided eye. The effect is a warm frame around a cool line — the contrast that makes yellow gold worth choosing here rather than a default.

The same idea in 18K rose gold at 3.54 ct, or in white gold at 3.40 ct with every stone graded F. Full range: tennis bracelet collection.
