Engagement Ring - Solitaire Setting
Solitaire settings are the classic settings for engagement diamond rings. These beautiful engagement ring settings are stylish for all shapes of diamonds - Round, Oval, Pear, Marquise, Emerald, Heart, Radiant and Asscher. The advantage of these settings is that light gets to the stone and reveals the diamonds' brilliance and true colors. The disadvantage is that the engagement ring settings offer less protection to the stone. These settings are the most popular form chosen for engagement ring settings.

Article - Diamond Certification
It is crucial when choosing a diamond to review the diamond certificate, also known as a Diamond Grading Report. This report documents the internationally recognised characteristics of a diamond, its carat weight, colour, clarity, cut.
A diamond certificate, also called a diamond grading report , diamond dossier ® or diamondquality report , is a report created by a gemmologist, or gemmologists, who have scrutinizedthe diamond and placed it under a microscope to analyse its dimensions, clarity, cut, colour,finish, symmetry, and other characteristics.
There are some of the most respected laboratories in the diamond industry. These laboratories are known for having the most strict, consistent, and unbiased systems for grading diamonds. Diamonds that are accompanied by these grading reports are the most highly valued in the industry, as their quality is considered guaranteed.

How GIA Estimate a Cut Grade ?
GIA estimate a Diamond Cut Grade with advances in computer modeling. They have been able to unlock the mystery of diamond cut — arguably the most complex and contested of the 4Cs. After more than 15 years of research and discovery, GIA has developed a scientific way to assess — and predict — the cut quality in round brilliant cut diamonds.
GIA has also developed software that provides a method of estimating a cut grade — and a database that is embedded into a number of leading diamond measuring devices so that this estimation can be automated. As a result, manufacturers can plan and, in effect, predict cut grades, buyers can compare cut qualities, and retailers can communicate the effects of cut on round brilliant diamonds.

How do you choose that breathtaking diamond whose brilliance will reflect the enduring bond of love it represents? First you must understand what makes one diamond more valuable than another. A diamond's worth is determined using the 4 C's of diamond selection which are Cut, Clarity, Color, and Carat.
Cut
The cut is what really gives the diamond its brilliance or luster. It is not only the shape, but also its number of facets, proportions, polish and symmetry. The most popular diamond cuts are: round, princess, marquise pear, emerald and oval. However, other fancy cuts are available.
Color
The closer a diamond's color is to colorless, the more valuable a diamond. Despite this, most diamonds do show a trace of yellow, brown or gray. Color is based on a predetermined alphabetical scale ranging from D to Z. D-F is colorless and most rare. G-J is near colorless with good to very good color. K-M is lightly colored, but has noticeable yellow or brown tint.
Clarity
Clarity refers to the number and type of inclusions or slight imperfections present in a diamond. The fewer the number of inclusions, the greater the value of the diamond. Diamond transparency, which refers to the cloudiness of a diamond, also affects its value. The following are abbreviations for classifications that are used world wide to describe the clarity of a diamond:
IF, FL: Internally flawless.
VVS1, VVS2: Near flawless and extremely difficult to impossible to find any inclusions under magnification.
VS1, VS2: Completely clean to the naked eye, and moderately to very difficult to find inclusions under magnification.
SI1, SI2, SI3: Completely to almost completely clear to the naked eye (eye clean) when viewed from the top.
I1, I2, I3: May or may not be easy to find imperfections with the naked eye, but easily visible under magnification.
Carat
The carat of a diamond refers to its weight. The larger the carat is the more rare and valuable the diamond. Diamonds are described in ¼ increments. It is important to remember that two diamonds of equal carat may reflect different values due to cut, clarity and color.
