Diamonds with large fracture inclusions can be processed to enhance its clarity. If the fracture opens up to the surface, glass like material with reflective index similar to that of the diamond (2.42) can be injected into the crack to diminish its appearance. Certain fracture in the diamonds can practically dissappear after this process to visually improve its clarity.
Such enhancements are a cosmetic process and does not alter the other characteristics of a diamond. The filler material can be removed at our lab if required to revert back to the natural appearance of the diamond.
Please refer to the FAQ section to see samples of diamond inclusions that are suitable for this treatment.
A single concentrated carbon spot in a diamond due to its multiple internal reflection can give an impression of heavy inclusions in other wise nice brilliant cystal. These spots can be bleached out by drilling microscopic tunnel and then injecting solvents to dissolve. This process is can reduce or eliminate concentrated black carbon inclusions and hence improve the clarity and overall looks of the diamonds.
This process is can reduce or eliminate concentrated black carbon inclusions and hence improve the clarity and overall looks of the diamonds. The process is non-reversible and it may leaves a microscopic tunnel which can be seen only under powerfull microscopes.
