I can share my positive experience with minimally treated diamonds, especially those coming from India. For me, they were a great choice because their natural beauty is truly unique. Such diamonds retain almost the original shape and have a special character that fully treated stones do not have. When I purchased such a diamond, I was pleasantly surprised by its natural clarity and rarity. It does not look like all standard diamonds, which makes it truly exceptional and unique.

This approach makes the stone more “alive”, it seems to carry the history of nature. In addition, such diamonds are usually slightly cheaper compared to fully treated ones, which can be an important factor when choosing.
