For example, a buyer expecting a 1 carat (200 mg) diamond solitaire engagement ring may be unwilling to accept a 0.99 carats (198 mg) diamond. [citation needed]
At standard temperature and pressure, 20 °C (293 K) and 1 standard atmosphere (0.10 MPa), the stable phase of carbon is graphite, but diamond is metastable, with a significant kinetic energy barrier that the atoms must overcome in order to reach the lower energy state, [12] and its rate of conversion to graphite is negligible, with a timescale ...
If they require a re-cut, they will be less valuable than a similar, newly polished diamond. [1] Within the diamond industry, recycled diamonds of smaller sizes, typically one-fifth of a carat or smaller, are traded in parcels of mixed diamonds known as a "melee" and are typically bought by jewelry manufacturers, diamond manufacturers and dealers.
The carat (ct) is a unit of mass equal to 200 mg (0.00705 oz; 0.00643 ozt), which is used for measuring gemstones and pearls. The current definition, sometimes known as the metric carat, was adopted in 1907 at the Fourth General Conference on Weights and Measures, [1] [2] and soon afterwards in many countries around the world.

In addition to naming the diamond the winner would receive P25,000 (about $2,170). [14]
