Loose Diamonds

As a loose diamond broker, we sell loose diamonds at below wholesale prices (based on the current Rapaport report). We sell diamonds certified exclusively by either the GIA (Gemological institute of America) or the EGL (European Gemological Laboratories).

As always, we wish to provide our customers with the information they require when selecting the item that is right for them. With that in mind, we invite you to review our shopping tips section to learn more about choosing a diamond. Click here for tips on diamond shopping.

Diamond Jewelry

Katzo is just one of the several premier designers of diamond jewelry you'll find at Milner's Jewelers. From classic to contemporary and from simple to elegant, we offer diamond jewelry of distinction - diamonds that get noticed.

Buying a Diamond

The Four Cs

The value of a diamond is not determined by a single factor. Rather, it is the combination of several elements - cut, color, clarity and carat weight that allows us to assess the quality of these special jewels.

1. Cut

The Ideal Cut
When a round brilliant diamond has been cut to "Ideal" proportions by a master cutter, it is a splendor to behold.

The Ideal Cut Diamond describes a round brilliant diamond that has been cut to exact and mathematically proven proportions. Its symmetry, with 58 exactly placed facets, produces the ultimate in luster and beauty.

When a diamond is cut to the ideal proportions, all of the light entering from any direction is totally reflected through the top and is dispersed into a display of sparkling flashes and rainbow colors.

The Premium Cut
A Premium Cut diamond demonstrates subtle variations from the Ideal Cut. Although dimensional differences affect a diamond's reflection of light, a Premium Cut still achieves a harmonious balance between its proportions and the display of brilliance.
Diamond Cut and Light

Ideal and Premium Cut Diamonds

 
THE IDEAL CUT
Light* entering the diamond reflects internally from facet to facet and is reflected back through the top ONLY, creating maximum brilliance.

Inferior Cut Diamonds
Most diamonds are "spread" in their cutting to retain maximum weight from the original rough. A heavier diamond will result, but at a dramatic sacrifice of potential fire and brilliance.

 
TOO DEEP
When a diamond is cut too deep, light* leaks out of the bottom, brilliance is lost and the center of the diamond will appear to be dark.
 
TOO SHALLOW
When a diamond is cut too shallow, light* leaks out of the bottom, brilliance is lost and the diamond appears watery, glassy and dark.

*Arrows on the diagram simulate the flow of light in the diamond.

2. Color
Most diamonds, although appearing colorless, actually have slight tones of yellow or brown. As these tones become more easily apparent, the rarity and the cost decrease. Ideal cutting dramatizes the rare splendor of a diamond because it produces such dazzling brilliance.

3. Clarity
Practically all diamonds contain naturally occurring internal characteristics called inclusions. The size, nature, location and amount of inclusions determine a diamond's clarity grade and affect its cost. One unique advantage of the Idea Cut is that its sparkle can mask otherwise noticeable inclusions.
FL-IF 
No inclusions visible (by an expert) under 10x magnification. (FL=Flawless, IF=Internally Flawless)
VVS1-VVS2
Minute, extremely difficult to find under 10x. (VVS=Very, Very Slight inclusions)
VS1-VS2
Minor, difficult to find under 10x. (VS=Very Slight inclusions)
SI1-SI2
Noticeable, relatively easy to find under 10x. (SI=Small Inclusions)
I1-I2
Obvious under 10x and just visible to the naked eye. (I=Imperfect)


4. Carat Weight
The weight of a diamond is measured in carats. One carat is divided into 100 parts called "points", 1 ct. = 1.00; 1/2 ct. = 0.50. The value of two diamonds of the same weight can vary greatly depending on the color, clarity and especially the cut. To the right are two identical pieces of rough, (uncut diamonds) each of the same quality and value.

Example 1. From one piece of rough a diamond has been cut to ideal proportions, retaining a weight of one carat. The light is totally reflected through the top.

Example 2: The second piece of rough has been "spread" in its cutting, resulting in a diamond weighing approximately 1.40 ct. Note: The girdle is thicker, the table is much larger, the angles are exaggerated, all at the expense of that diamond's ability to reflect light.

Therefore, one can see that the value of a diamond can vary as much as 40% in the cutting alone.
