Introducing Brilliance Diamond®
Bella Cosa Jewelers is proud to introduce our very own signature diamond collection - Brilliance Diamond®. We have gone through thousands of Gemological Institute of America (GIA) and American Gem Society (AGS) graded loose diamonds and we have hand-selected the ones that meet our extremely strict standards.
This process means that each diamond has been carefully chosen to be considered a Brilliance Diamond®. Each Brilliance Diamond® comes with two certificates: one from GIA and one from AGS. These diamonds achieve the highest cut grade possible on both the GIA and AGS grading reports. Of the 4 Cs of diamonds, cut is what matters the most, as it can affect over 50% of the value of a diamond. Cut is what allows the diamond to sparkle and is what brings out the inner beauty of the diamond. Just like every facet of your life matters, we also believe that "Every Facet Matters" when it comes to the diamond that will be part of your special moments forever.
When a diamond interacts with light, every facet affects the amount of light returned to the eye. Each facet of a Brilliance Diamond® aligns precisely with all other facets, which enables the diamond to reflect and return to the eye the maximum light possible. This leads to the unprecedented brilliance, fire, and sparkle of a diamond. Simply put, when buying a Brilliance Diamond®, you're getting the very best of the best.
What Makes a Diamond a Brilliance Diamond®?
AGS Triple Ideal
American Gem Society Laboratories (AGSL) use a 0-10 grading scale with 0 being the best (Ideal). It is easy to understand: the highest possible grade is zero, and the lowest grade is 10. One can think of the top grade as having “zero deductions”. The AGS 0 grade is the world's strictest laboratory standard for Cut. An AGS000 or Triple zero is the absolute highest cut grade that a diamond can have. An AGS000 has unprecedented brilliance and fire. The very rare combination of ideal proportions, ideal polish and ideal symmetry results in an AGS000 or Triple Zero. It is extremely difficult to locate a diamond where all three cut factors are totally ideal.
GIA Triple Excellent
Cut quality is the factor that fuels a diamond's fire, sparkle and brilliance. The GIA Diamond Cut Grading System for standard round diamonds is based on seven components: brightness, fire, scintillation, weight ratio, durability, polish and symmetry. Each cut grade, based on a relative scale from Excellent to Poor, represents a range of proportion sets and face-up appearances. "Triple Excellent" means the diamond has achieved an excellent grade for cut, polish and symmetry. However, GIA's excellent cut grade includes a wide range of cut parameters and not all triple excellent diamonds have top light performance. In order to be eligible to become a Brilliance Diamond®, a diamond has to meet other strict standards besides being a GIA Triple Ex.
To become a Brilliance Diamond®, a diamond has to meet many other strict standards other than being an AGS 000 and GIA Triple Ex.
TABLE: 55% - 60%
A diamond's table is the largest facet of the stone, compromising the flat surface on the top. The most ideal table for round diamonds is between 55%-60%. At this portion, the table is large enough to allow light to enter the diamond at the correct angles to reflect and refract off the smaller facets below. The result is a fiery and brilliant display.
DEPTH: 59% - 62.5%
The depth percentage is the depth divided by the width. The percentage dictates the overall proportions of the diamond, which in turn directly impacts how light reflects off the facets in the diamond. The ideal depth for round diamonds is between 59%-62.5%, which allows light to bounce around the facets, creating that gorgeous, eye-catching sparkle.
None or Faint Fluorescence
No glow or a very slight blue glow is emitted when the diamond is exposed to UV light. The diamond has minor or no elements that cause the stone to fluoresce when exposed to UV light.
No Brown, Grey or Green Tints of Color
The shade of the body color of the diamond is not brownish, greenish or greyish.
No Extremely Thin or Very Thin Girdles
The girdle is the outer edge of the diamond. A very thin or extremely thin girdle can allow the stone to chip during normal wear.
Like a knot in a piece of wood, a diamond knot is a natural crystal in the stone that reaches the surface. Under proper lighting conditions, a knot can often be seen with the naked eye.
No Cloudy or Milky Diamonds
Brilliance Diamond™ does not have a milky or cloudy appearance.
At Bella Cosa Jewelers we only purchase from suppliers that adhere to the Kimberley Process and are concerned about the ethical and social issues that surround diamonds. All loose diamonds are purchased from De Beers sightholders who guarantee in writing that their diamonds are conflict-free.
