What we do!

Lemon TechnoMist – Imagineering Diamonds

Till very recently, the color of a diamond was based on judgment at the rough stage. There are companies which still have the same system. However, at Lemon TechnoMist, we use science and technology to accurately estimate the color of a stone at the rough stage itself. And you would be surprised that a single stone could give you a D color or an E or an F or even Fancy Colour depending on how exactly it is designed, cut and polished. This allows maximizing the value of a diamond. For us, each stone is a project with the mission to optimize its value through design based on the optimum combination of shape, color, purity and cut.

An unstoppable R&D and latest technical knowhow, institutionalized into substantive processes and proprietary technology analyzing billions of combinations of various parameters are used by LTM to convert an uncut stone into a Polished master piece.
