HORIBA, the Japanese maker of analytical and measuring instruments, said on February 3, 2026 that its Indian subsidiary had bought all of the shares of Pristine Deeptech, a research startup in Gujarat that works on lab-grown diamond for semiconductor and quantum applications. The acquisition took effect on January 14, 2026, and Pristine Deeptech is now a wholly owned subsidiary of HORIBA India.
HORIBA did not disclose the price. Pristine Deeptech had seven employees on the date the deal closed, and its chief executive is Ashvani Kumar.
The two companies were not strangers. They had a business relationship from 2023, and HORIBA marked the closing with a ceremony on February 2 attended by Kumar, HORIBA director Hideyuki Koishi and HORIBA India president Rajeev Gautam.
What Pristine Deeptech built
Pristine Deeptech was set up in October 2021 under the name Pristine Diamonds Private Limited and later changed its name. It is based in the Vatva industrial estate in Ahmedabad.
The company does research and development on using lab-grown diamond as a working material rather than as a gemstone. Its expertise lies in diamond research and in vacuum technology, which is used in the processes that grow synthetic diamond.
HORIBA's announcement did not name the startup's founders or mention any outside investors or funding rounds.
Why diamond matters to chipmakers
Diamond conducts heat very well and can withstand strong electric fields before breaking down. Those properties make it a candidate material for next-generation power semiconductors and for quantum sensors. HORIBA also listed 5G and 6G communications, electric vehicles, data centers, and aerospace and defense as areas where diamond-based components could be used.
HORIBA expects the use of lab-grown diamond to grow substantially over the next decade. As a supplier of measurement equipment to semiconductor and materials makers, it wants to be able to test and characterize the material as demand rises.
What HORIBA plans to do
HORIBA set out three goals for the acquisition. The first is to combine Pristine Deeptech's knowledge of diamond with HORIBA's own analytical techniques, including Raman spectroscopy, to build measurement solutions for advanced materials such as diamond wafers.
The second is to develop diamond sensors and components, both for use inside HORIBA's own instruments and for sale as separate products. The third is to grow HORIBA India into a research and development hub for the group's advanced materials and semiconductor business. HORIBA did not attach a timetable or an investment figure to any of the three goals.
HORIBA already has research sites in France, the United States and the United Kingdom. The company said it sees India as a possible future center for global innovation.
Terms and people
HORIBA said neither the purchase price nor the capital involved would be made public. The buyer was HORIBA India Private Limited rather than the Japanese parent, HORIBA, Ltd., although senior group executives took part in the closing.
Hideyuki Koishi, who attended the ceremony, sits on the board of HORIBA, Ltd. and chairs HORIBA India. Rajeev Gautam is a corporate officer of HORIBA, Ltd. as well as president of the Indian unit. Ashvani Kumar was listed as Pristine Deeptech's chief executive in HORIBA's outline of the company after the deal closed, and HORIBA did not announce any change to the startup's leadership.
HORIBA's business in India
HORIBA India was established in 2006 and is headquartered in New Delhi. It sells, services and manufactures analytical equipment for the energy and environment, bio and healthcare, and materials and semiconductor sectors, and had 550 employees at the end of December 2025.
Pristine Deeptech, with its seven staff, is a small addition to that operation. Entrepreneur India, which described the target as an R&D-driven startup, reported the deal as a way for HORIBA to deepen its diamond technology expertise and set up a research hub in the country.
