Why it may matterVerify against the original reporting

The article frames lab-grown diamonds as a secular growth driver with higher margins (60–65% vs 40–45%), which could boost Signet's AUR and SSS. Positive analyst commentary (Raymond James) and SIG's recent forecast raise reinforce upside potential in the near term.
