Description
This is the generic modified brilliant cut anvil where the table/culet orientation is random, and therefore not {100}.
The modified brilliant diamond anvil design is derived from the traditional round brilliant cut used in jewellery. It developed as a way of maximising back reflection and spectral dispersion, but is not necessarily the design which gives maximum strain.
A modified brilliant diamond cut stone has a table polished in 16 facets. As such the culet is also 16-sided.
With the girdle Y being 100%, the other dimensions are:
- table: 58%-62%
- crown height: 12%-16%
- crown angle: 34°-37°
- girdle thickness: 3.5%-4.5%
- pavilion depth: 42%-45%
- pavilion angle: 40.7°-41.7°
