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 ...
Most Ia diamonds are a mixture of IaA and IaB material; these diamonds belong to the Cape series, named after the diamond-rich region formerly known as Cape Province in South Africa, whose deposits are largely Type Ia. Type Ia diamonds often show sharp absorption bands with the main band at 415.5 nm (N3) and weaker lines at 478 nm (N2), 465 nm ...

The most common impurity in diamond is nitrogen, which can comprise up to 1% of a diamond by mass. [13] Previously, all lattice defects in diamond were thought to be the result of structural anomalies; later research revealed nitrogen to be present in most diamonds and in many different configurations.
WD Lab Grown Diamonds Logo. WD Lab Grown Diamonds was a manufacturer of synthetic chemical vapor deposition (CVD) diamonds, headquartered in the Washington, D.C. area.
