Why the diamonds have different prices?
It depends from : Colour, Cut, Shapes, Clarity, Size.
Color refers to a diamond's lack of color, grading the whiteness of a diamond.
A color grade of D is the highest possible, while Z is the lowest.
D Absolutely colorless. The highest color grade. Extremely rare.
F-E Colorless. Minute traces of color can be detected by an expert gemologist. A rare diamond.
H-G Near-colorless. Color difficult to detect unless compared side-by-side against diamonds of better grades. An excellent value.
J-I Near-colorless. An exceptional value with slightly detectable warmth or tone.
M-K Noticeable color.
Z-N Noticeable color.
Cut is a diamond's most important characteristic.
It has the greatest overall influence on a diamond's beauty.
It determines what we generally think of as sparkle.
A diamond's cut grade is an objective measure of a diamond's light performance, or, what we generally think of as sparkle. When a diamond is cut with the proper proportions, light is returned out of the top of the diamond (which gemologists refer to as the table). If it is cut too shallow, light leaks out of the bottom; too deep and it escapes out of the side.
Ideal cut: Represents roughly the top 3% of diamond quality based on cut. Reflects nearly all light that enters the diamond. An exquisite and rare cut.
Very good cut: Represents roughly the top 15% of diamond quality based on cut. Reflects nearly as much light as the ideal cut, but for a lower price.
Good cut: Represents roughly the top 25% of diamond quality based on cut. Reflects most light that enters. Much less expensive than a very good cut.
Fair cut: Represents roughly the top 35% of diamond quality based on cut. Still a quality diamond, but a fair cut will not be as brilliant as a good cut.
Poor cut: Diamonds that are generally so deep and narrow or shallow and wide that they lose most of the light out the sides and bottom. Blue Nile does not carry diamonds with cut grades of poor.
Clarity is a measure of the number and size of the tiny imperfections that occur in almost all diamonds.
Many of these imperfections are microscopic, and do not affect a diamond's beauty in any discernible way.
Much is made of a diamond's clarity, but of the Four Cs, it is the easiest to understand, and, according to many experts, generally has the least impact on a diamond's appearance. Clarity simply refers to the tiny, natural imperfections that occur in all but the finest diamonds. Gemologists refer to these imperfections by a variety of technical names, including blemishes and inclusions, among others. Diamonds with the least and smallest imperfections receive the highest clarity grades. Because these imperfections tend to be microscopic, they do not generally affect a diamond's beauty in any discernible way.
Flawless, Internally Flawless: No internal or external imperfections. Internally Flawless: No internal imperfections. Very rare.
Very, Very Slightly Included: Very difficult to see imperfections under 10x magnification. An excellent quality diamond.
Very Slightly Included: Imperfections are not typically visible to the unaided eye. Less expensive than the VVS1 or VVS2 grades.
Slightly Included: Imperfections are visible under 10x magnification, and may be visible with the unaided eye. A good diamond value.
YELLOW DIAMONDS, called FANCY.
Only one in every 10,000 diamonds possesses natural color and is referred to as a fancy color diamond. For this reason, fancy color diamonds are purchased almost exclusively for the intensity and distribution of the diamond's color. Criteria considered when purchasing a white or colorless diamond, such as cut proportions and clarity, are less important when purchasing a fancy color diamond.
Color intensity, the deepness or richness of color, is the most important consideration when purchasing a fancy color diamond. The more intense the color, the rarer and more valuable the diamond will be. Fancy color diamonds are graded in order of increasing intensity from
Faint,Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Dark, and Fancy Deep.
After color grade, carat weight has the most impact on price for fancy color diamonds. When diamonds are mined, large gems are discovered much less frequently than small ones. This makes large diamonds much more valuable. For this reason, diamond prices for fancy color diamonds rise exponentially with carat weight. Learn more about carat weight in our Diamond Education section.
Due to the nature of fancy color diamonds, clarity is less important than it is in their colorless counterparts. This is true because inclusions tend to be masked by the diamond's color.
Fancy color diamonds are primarily cut to emphasize their color. This contrasts with colorless diamonds that are cut to maximize sparkle or brilliance, which in some instances can detract from the natural color of a fancy color diamond. While fancy color diamonds still exhibit brilliance, color is the most important characteristic considered when they are being cut.
OUR PEARLS : AKOYA and TAHITIAN
Akoya pearls are the specialty of Japanese pearl farms. The first pearls to be cultured early in the 1920s, their white color and rosé overtone complement a fair complexion. Because Akoya pearls are a high-quality pearl, you'll find them set with gold posts and clasps, and you'll find they are well matched for size, shape, and color. You'll also find few blemishes and a deep, beautiful luster.
Tahitian cultured pearls offer a dramatic touch. The natural black color of these pearls comes from the color of the oyster's black lips.
These pearls are traditionally called "black," but their color can range from a metallic silver, to the color of graphite. And within this range of colors they can have bluish, purplish, or greenish overtones.
Tahitian cultured pearls are cultivated from the black-lipped variety of the pinctada maxima oyster which reaches a foot or more in diameter, and produces very large pearls. This oyster is very sensitive to the pearl culturing process, which makes the pearls very costly to produce.
OUR GOLD, ONLY 18 K and NOT ONLY YELLOW.
The pure gold should be 24 k but is too soft for everyday wear and for the jewelry,
We craft our jewelry using both 18k.
18k gold is composed of 75% gold, which is alloyed with other metals to make it strong enough for everyday wear. 14k gold is composed of 58.3% gold and 41.7% of other metals.
Natural gold and color-saturated alloys are what give yellow gold jewelry its rich shine. The alloys most commonly used, are copper with a red hue, and silver featuring a green hue. An expert mixture of copper, silver and pure gold gives this precious metal its signature warmth.
A silvery white character is what makes white gold jewelry so appealing. In order to make the gold white, it is combined with metal alloys that are white in nature and plated with an extremely hard element called rhodium. Although strong, rhodium may wear away over time. Replating is a simple process that can be done to restore whiteness to your jewelry.
WHITE GOLD WITH BLACK RHODIUM
Black rhodium is plated to white gold creating a rich black appearance that is extremely hard and strong. As with traditional white rhodium, black rhodium may wear away over time. Replating is a simple process that Blue Nile offers to restore your jewelry's black finish.
The beautiful pink hue of rose gold jewelry is created by using a copper alloy. Again, the overall percentages of metal alloys is the same for rose gold as it is for yellow or white, there is just a different mixture in what alloys are used.
