Band Width

The width of a ring's band is measured in millimeters and can range from 1mm to as wide as 20mm. However, the standard band widths most people go for range from 1.5mm or 2mm up to 6mm.

Choosing the Width of a Ring Band

Most ring widths are measured in millimeters or “mm” for short, even in countries that use inches, such as the USA. Due to this, it can be difficult for our metric system thinking minds to imagine how wide an "x" mm band will be.

Here's some help! Below you can see common ring widths in millimeters converted to inches, using a nickel as reference.

Engagement Ring Head | Height

The head is the primary object that holds in the Diamond. The head is made up of the Prongs (however many Prongs that may be), along with the base and usually a peg on the bottom to hold it to the mounting.

What Causes Inclusions & Blemishes?

Diamonds will take over a period of between 1 and 3 billion years to form. Despite their unique structure and composition, it is inevitable that the stones acquire flaws and imperfections along the way. The diamond cutter will take great effort to work around these flaws. A long process, usually complicated by fault lines, dictates where the cut will be made.

Flawless diamonds aren’t common and become extremely rare once sizes get above 2 carats. Most rough stones large enough from which to produce larger diamonds rarely are free of inclusions.

Diamond Clarity

The GIA Clarity Scale contains 11 grades, with most diamonds falling into the VS (very slightly included) or SI (slightly included) categories. In determining a clarity grade, the GIA system considers the size, nature, position, color or relief, and quantity of clarity characteristics visible under 10× magnification.

Diamond Color

GIA's color-grading scale for diamonds is the industry standard. The GIA scale begins with the letter D, representing colorlessness, and continues with increasing presence of color to the letter Z, representing light yellow, light brown or light gray. The 23 color grades on the GIA Color Scale (or diamond color chart) are subdivided into five subcategories, which are: colorless (D-F); near colorless (G-J); faint (K-M); very light (N-R); and light (S-Z).

How a Diamond's Carat Weight is Determined

Just as a dollar is divided into 100 pennies, a carat is divided into 100 points. For example, a 50-point diamond weighs 0.50 carats. But two diamonds of equal weight can have very different values depending on the other members of the Four C's: clarity, color and cut.

Carat Weight & Size | Round Diamonds

Carat is the globally recognized standard for the weight of a diamond. Contrary to popular belief, the carat is not the size of the diamond. A diamond's size is measured in millimeters, length by width.

It typically takes about 250 tons of rock mining to produce a single 1 carat diamond. That's why diamonds are rare and expensive.

All else being equal, diamond price increases with diamond carat weight because larger diamonds are rarer and more desirable. However, two diamonds of equal carat weight can have very different values (and prices) depending on three other factors of the diamond 4Cs: Color, Clarity, and Cut.

How a Diamond’s is Size Determined

A metric “carat” is defined as 200 milligrams. Each carat is subdivided into 100 'points. ' This allows very precise measurements to the hundredth decimal place. A jeweler may describe the weight of a diamond below one carat by its 'points' alone.
