DID YOU KNOW...
Less than 1% of all diamonds ever found have had no inclusions and can be called flawless (FL) or internally flawless (IF)
In all diamonds, except the most rare, tiny traces of minerals, gasses, or other elements were trapped inside during the crystallization process.
These are called inclusions, but are more like birthmarks! They may look like tiny crystals, clouds, or feathers and
they're what make each diamond different and unique.
DID YOU KNOW...
Diamonds occur naturally in all spectral colors, from red to blue, however the most commonly occurring colors are yellow and brown.
Diamonds of a colorless grade in the D-F range are much more valuable than diamonds in the L-P range because of the rarity of these colorless diamonds.

Less than 1% of all the women in the WORLD will own
a diamond of 1.0ct or more?
Given that diamonds form under tremendous heat and pressure, internal and external characteristics (inclusions) are common. It is virtually impossible to find a diamond without any inclusions or ‘natural markings’. These natural fingerprints are often invisible to the naked eye, but under magnification one can begin to identify minute clouds, dark spots or crystals. The smaller and fewer inclusions in a diamond, the more rare the diamond and the more valuable it becomes.
Keep in mind, diamond clarity is largely related to natural rarity, and in most cases have little or no effect on VISUAL BEAUTY. All diamonds are graded according to their appearance; & inclusions are ranked on a scaled of perfection.
Flawless – No internal/external flaws; very rare
IF (Internally Flawless) – Slight external blemishes, but no internal flaws
VVS1, VVS2 – Very, very slightly included 1 & 2. Minimal inclusions, excellent quality and cannot see inclusions to the naked eye.
SI1, SI2 – Slightly included 1 & 2; visible inclusions under magnification, but cannot always be seen to the naked eye. A good clarity to be searching for.
I1, I2, I3 – Inclusions visible to the naked eye.
The diamond color evaluation of most gem-quality diamonds is based on the absence of color. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. GIA's D-to-Z diamond color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to masterstones stones of established color value.
GIA's diamond D-to-Z color-grading scale is the industry's most widely accepted grading system. The scale begins with the letter D, representing colorless, and continues, with increasing presence of color, to the letter Z.
Many of these color distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference in diamond quality and price.
(S through Z)
Very Light Yellow
(N, O, P, Q, R)
(K, L, M)
(G, H, I, J)
(D, E, F)
The term carat is the most easily understood of the 4 C’s, and is used to express the weight of a diamond. Diamond weight may also be referred to as points. A 1-carat diamond is equal to 100 ‘points’. A ¾- carat diamond equals 75 ‘points’, like pennies to the dollar.
the four c's
A polished diamond’s beauty lies in its complex relationship with light; (reflects & refracts) how light strikes the surface, how much light enters the diamond, and in what form light returns to your eye. A diamonds ‘cut quality’ has three major components:
Proportions – the size and angle relationships that exist between the diamond’s facets. Key proportions include table size, crown angle, girdle thickness, & pavilion depth
Symmetry – refers to the exactness of the shape and arrangement of facets.
Polish – The smoothness and luster (shine)of the diamond’s facet surfaces.Polish creates scintillation – the dance of light that a diamond displays.
"Every diamond is a miracle of time and place and chance. Like snowflakes, no two are exactly alike.
Until the middle of the twentieth century, there was no agreed-upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut, and Carat Weight. Today, the 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world.
The creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase."

DID YOU KNOW...
A diamond with perfect color & perfect clarity could nevertheless, have poor brilliance if it is not well cut.
The Sweet's consider CUT to be the most important property to note when choosing a diamond, no matter what shape or size.
