What to watch

  • Launch of Tanishq-specific natural versus lab-grown diamond collections, pricing ladders or exchange policies.
  • Use of QR-coded digital certificates, named laboratory reports or explicit treatment-disclosure labels in stores and online.
  • Competitor announcements from Kalyan, Malabar, Reliance Jewels, Senco or regional chains on authentication and provenance.
  • Changes in diamond mix, average selling price, diamond-jewellery growth and gross-margin commentary in Titan earnings.
  • Indian regulatory, trade-body or consumer-protection guidance on lab-grown diamond nomenclature, certification and disclosure.
  • Consumer complaints, social-media scrutiny or media investigations involving undisclosed treatments or diamond misrepresentation.
  • Expand point-of-sale education that visibly distinguishes natural, lab-grown, treated and imitation stones, with plain-language certificates and QR-linked reports.
  • Package authentication as a customer service proposition, including pre-purchase consultation, post-purchase verification and trade-in valuation support.
  • Use R&D capability to standardise testing protocols across stores and franchise touchpoints, reducing risk of inconsistent disclosure.
  • Develop separate merchandising, pricing and communication architectures for natural and lab-grown diamond collections.
  • Pursue third-party accreditation, auditable provenance partnerships or independent laboratory validation to strengthen credibility beyond brand claims.
