Scintillation brilliance
Scintillation is the term used for the changing colors, the radiance and sparkle of the rays when the stone is moved or when the light source changes.
SCINTILLATION:
A general term referring to the flashes of light seen when a diamond moves. Also used to describe the patterns of light and dark areas seen in a diamond.

Scintillation
Scintillation refers to the flashes of light, or sparkles, which are produced when a diamond is tilted from side to side.
Scintillation
As the diamond, observer or light source is moved, reflections and flashes of white light (scintillation) emanate from the diamond's surface.
Scintillation
Scintillation is the sparkle effects in a Diamond caused by the contrast of light and dark areas. When you tilt your Diamond and see the twinkles, that's Scintillation.
scintillation The breaking up of light into tiny constituents, a function of the facets of a gem.
seal stone A gem carved in intaglio producing a design in relief, when pressed into clay, usually the owner's signature or emblem.
Scintillation is the flashing or sparkling of light which occurs when either the diamond or light source are moved.

Scintillation - Winking or flashing of light from the facets of a diamond as it moves. Scintillation explains why diamonds are much more beautiful when they are in motion.
Scintillation: When light reflects from a diamond, the sparkling flashes that come from the facets of the gem are known as scintillation.
Scintillation (or Sparkle): The combination of fire (dispersion) and brilliance. It is the amount of light that reflects out of a diamond as it moves. It is also called ‘sparkle'.

Scintillation: Scintillation (flashing or twinkling of light) in gemstones refer to the alternating display of reflections from the polished facets when in motion.
scintillation It is the movement of the reflections (brilliance) and dispersion (spectral colors), as the diamond (or other gemstone) is rotated or tilted before the viewer's eyes.

Scintillation (‘sparkle'). This is an important factor in faceted stones. A gem cut with a smooth, cone-shaped pavilion could display full brilliance, but would lack scintillation.

Scintillation
The sparkle or flash emitted by diamonds when they are moved under light.
Screw Back
Screw backs are typically used for diamond earrings. This secure backing features small metal backs that screw onto the post.
They are luster, brilliance, dispersion, and scintillation. Luster can be described as the quality and amount of light that is reflected off the surface of a diamond.
Scintillation (n) Used to describe a secondary quality aspect of a gem's brilliance, scintillation describes sparkle created with movement of the stone. One of the three categories of 'brilliance', 'fire or dispersion' and 'scintillation'.
While some of Zultanite's key characteristics are its delicate color saturation, durability and scintillation (play of light), the beauty and intrigue of this regal gemstone ultimately lies in its different colors.
The cut is critical in the resulting sparkle, or scintillation, of the diamond. This is due to the way in which the stone reflects light back to the eye.
Optical properties are important because they provide a nondestructive means for identifying gemstones and are responsible for all the features one immediately observes and admires including color, luster, brilliance, scintillation, and dispersion, ...
If a stone is cut flatter, then it will appear bigger, while a deeper cut stone will be smaller, but may have more brilliance and scintillation.
Below are the approximate proportions to create a round diamond of maximum beauty, achieving an excellent balance between brilliance, fire and scintillation. (NOTE: These proportions only apply to round diamonds.
The beauty of gems justifies with its color, luster, brightness, brilliance, scintillation and dispersion. Optical properties are responsible to create all this qualities of a gem. These are also important to identify gemstones.
The diamond's brightness, fire, and scintillation are assessed and incorporated into the cut grade. The diamond's measurements, proportions, facet angles, polish, and symmetry are also factored into the final cut grade.
Through both practical experiments and theoretical suppositions, the proportions necessary to create the best balance of brilliance, dispersion and scintillation (play of light) were calculated.
"Facets of Fire": Keepsake's patented diamond cut with 74 facets that gives off more light and greater scintillation than a round-cut diamond.
Faith Ring: See Fede Ring.
False Topaz: A name for yellow quartz.
Sparkle
The 'sparkle' of a diamond is the combination of fire and brilliance. The light that reflects out of a diamond as it moves. Sometimes called "scintillation" by older dealers.
Stones
A word for diamonds and other precious gems.
Between about 1914 or 1919, the mathematician Marcel Tolkowsky calculated the optimum angles for round diamonds, and published a paper "Diamond Design", which gave specifications for an ideal cut to maximise the brilliance and scintillation of ...
Cut quality is an aspect of diamond grading that takes into account various factors, such as brightness, fire, scintillation, durability, weight ratio, polish, and symmetry.

Some materials such as NaI can "convert" an X photon to a visible photon; an electronic detector can be built by adding a photomultiplier. These detectors are called "scintillators" or "scintillation counters".

Ideal Cut Diamonds
You may have heard of a term called "Ideal Cut". This term refers to the attempt to cut a round diamond into the best proportions to achieve maximum brilliance, fire and scintillation.
'Sparkle' - also known as 'scintillation' - defines how much the diamond shimmers when you move it around in the light. When light enters the diamond, it is refracted and bounces back out in a rainbow of colors.
Diamonds are cut to a uniform ideal for maximum brilliance (white light reflections), fire (flashes of color) and scintillation (play of light). The quality and value of a diamond is rated by colour, cut, clarity and carat weight ...
The more efficiently a diamond is cut, the more light will return back to the eye. The diamonds that have the most brilliance and dispersion and scintillation are the ones that are cut the best.
Such a stone in a larger size (2 cts or more) is especially rare since so many larger pieces suffer from light extinction and are too dark. Cat'seye stones bring a premium price. Fine cutting enhances value considerably by adding scintillation and ...
Red tourmaline potentially may exhibit much better crystal than the green and blue varieties. The pavilion of red tourmaline is often cut with multiple tiny facets. The scintillation produced by this faceting style shows the gem's multicolor effect ...
of the light that enters a Diamond is refracted and reflected out, in the colors of the rainbow, this is known as "dispersion". When you move a Diamond the light reflects and refracts off the facets creating a flashing effect known as "scintillation".

Scintillation:The sparkle or flash created when a diamond is moved or struck by light. Scissors cut:A type of step cut where the facets are divided into four sub-facets by the "scissors".
