HPHT MONO CRYSTAL
DIAMOND CHARACTERISTICS
SHAPE
SPR’s HPHT supply typically features topped octahedron shapes but can include rhombidodecahedron or plate-like crystals for larger sizes or specific orientations.
COLOR
Diamond crystals develop a slight yellow tint during growth due to nitrogen atoms trapped in the lattice, a characteristic of Type Ib synthetic crystals with around 100 ppm nitrogen.
SIZE AVAILABILITY
The typical weight of our diamond crystals is 0.2 – 3.0 carats which covers most industrial diamond applications.
Chemical and Physical Properties
The advanced HPHT process and thorough sorting ensure not only consistent high-quality grown diamonds but also repeatability in terms of chemical, physical, and thermal properties.
