The fracture filling of diamond is often the last step in the process of diamond enhancement, following laser drilling and acid-etching of inclusions, though if the fractures are surface-reaching, no drilling may be required. The process involves the use of specially-formulated fillers with a refractive index approximating that of diamond.
Gemstone irradiation is a process in which a gemstone is exposed to artificial radiation in order to enhance its optical properties.High levels of ionizing radiation can change the atomic structure of the gemstone's crystal lattice, which in turn alters the optical properties within it. [1]
Certain diamond enhancement techniques are commonly used to artificially produce an array of colors, including blue, green, yellow, red, and black. Color enhancement techniques usually involve irradiation , including proton bombardment via cyclotrons ; neutron bombardment in the piles of nuclear reactors ; and electron bombardment by Van de ...
The silicon-vacancy center (Si-V) is an optically active defect in diamond (referred to as a color center) that is receiving an increasing amount of interest in the diamond research community. This interest is driven primarily by the coherent optical properties of the Si-V, especially compared to the well-known and extensively-studied nitrogen ...
It’s been five months, and Isabella's parents say she still hasn’t gotten her Medicaid back even though her brother — same family, same income — never lost his.

The Twilight Zone creator Rod Serling would have turned 100 on Dec. 25, 2024. To commemorate the anniversary, Rod’s daughters, Jodi and Anne, are looking back on some of their most meaningful ...
GH therapy should begin “at the most reasonably early point in the patient's growth when they're identified to be growth hormone deficient or have idiopathic short stature,” says Khatoon.
