From the Founder's Desk
Welcome to DGSL, since our founding in 2004, we’ve taken pride in standing at the forefront of gemological science and service.
At a time when transparency and reliability were elusive in the jewelry market, DGSL emerged as North India’s first diamond certification laboratory—setting new benchmarks for integrity, accuracy, and professionalism.
What started as a small, passionate endeavor has grown into a trusted name among jewelers, retailers, and collectors across India. We’ve always believed that every gemstone has a story to tell, and it is our responsibility to reveal it with scientific precision, professional competence and ethical clarity.
