MOND-compliant gravity, which explains galactic-scale observations, was not previously detected closer to Earth, such as in national laboratories or the trajectories of interplanetary spacecraft, because the a 0 acceleration, 1.2 × 10 −10 m/s 2, at which the dynamics of MOND begin diverging from Newtonian dynamics, is—as a practical matter ...
Type Ib make up about 0.1% of all natural diamonds. They contain up to 0.05% (500 ppm) of nitrogen, but the impurities are more diffuse: the atoms are dispersed throughout the crystal in isolated sites. Type Ib diamonds absorb green light in addition to blue, and have a more intense or darker yellow or brown colour than Type Ia diamonds.
Simplified atomic structure of the NV center. The nitrogen-vacancy center (N-V center or NV center) is one of numerous photoluminescent point defects in diamond.Its most explored and useful properties include its spin-dependent photoluminescence (which enables measurement of the electronic spin state using optically detected magnetic resonance), and its relatively long (millisecond) spin ...
Diamond is a good electrical insulator, having a resistivity of 100 GΩ⋅m to 1 EΩ⋅m [32] (1.0 × 10 11 – 1.0 × 10 18 Ω⋅m), and is famous for its wide bandgap of 5.47 eV. High carrier mobilities [ 33 ] and high electric breakdown field [ 34 ] at room temperature are also important characteristics of diamond.
Originally, the diamond had 169 facets and was 4.1 centimetres (1.6 in) long, 3.26 centimetres (1.28 in) wide, and 1.62 centimetres (0.64 in) deep. It was high-domed, with a flat base and both triangular and rectangular facets, similar in overall appearance to other Mughal-era diamonds which are now in the Iranian Crown Jewels .
After weeks of planning, an incision 0.5 inches (13 mm) deep was made to enable Asscher to cleave the diamond in one blow. Making the incision alone took four days, and a steel knife broke on the first attempt, [ 4 ] but a second knife was fitted into the groove and split the stone cleanly in two along one of four possible cleavage planes.

Because the first discovery sites were in the village of Middleville and in the city of Little Falls, respectively, the crystal is also known as a Middleville diamond or a Little Falls diamond. [ 3 ] Herkimer diamonds became widely recognized after workmen discovered them in large quantities while cutting into the Mohawk River Valley dolomite ...
