Our exceptional diamond cut quality provides us with a decisive competitive advantage. We specialise in round brilliant cuts from stars to pointers, in whites, TTLCs and TTLBs. We also carry a large selection of dossiers from 0.30-0.90 ct in D-K colours with VVS-SI clarities.

Corporate Social Responsibility

D Navinchandra Group is running a charitable trust under the name of the “Kalpana Dilip Mehta Foundation”. We underline our commitment to community improvement by making donations to different organisations and NGOs supporting education for underprivileged individuals, medical care and social programmes.

Recently, Kalpana  Dilip  Mehta Foundation had tied up with The Seven Hills Healthcare and Jivan Jyot  Bank  in setting up a Dialysis Centre offering free treatment to poor patients.

Trustees of Kalpana Dilip Mehta Foundation have contributed in setting up an OPD Centre at St Elizabeth Hospital, Mumbai and a ward at Conwest Jain Clinic Group of Hospital and also contributed to Mavjat Multispeciality Hospital in Palanpur, Gujarat India.

The Group has helped set up tribal schools and education centres in various villages in India  through donations to The Bharatmata Mandir Trust.

As one of the early members of the Responsible Jewellery Council, corporate, social and environmental responsibly is a high priority.
