Diamonds are known to man for centuries. The word Diamond is derived from the from the Greek word “adamas” meaning invincible. Ancient Romans regraded diamonds as splinters from falling stars, while Greek’s speculate it as the sparkling tears of the gods. Diamond is the hardest known substance found in the nature. Most diamonds are colour-less, if not icy-white. Diamonds also occur in variety of colours ranging
from – steel gray, white, blue, yellow, orange, red, green, pink to purple, brown and black. High dispersion of light make diamonds so mesmerising and perfect for jewellery. Gem diamonds are appraised by four C’s : Cut, Colour, Clarity and Carat weight. These four C’s are the cardinal aspects to consider while purchasing a diamond.
Cut determines the diamonds ability to sparkle. A well cut diamond can be distinguished by its aesthetic excellence of reflecting more light and will appear larger than it actually is. Diamond cut details encompasses diamond’s angles, proportions, symmetrical facets, brilliance, fire,scintillation and finishing details. A diamond well cut, will have greater brilliance, fire and scintillation, which conceal flaws. Pavilion angle is the decisive factor in how well a diamond reflects the light back to the viewer.
Cut being extremely important to a diamond’s aesthetic excellence, it’s indispensable to cherry pick diamonds with the assistance of trained eye’s. Beladamaz will assist you at every stage of the diamond selection process to make sure that you are getting most value out of each purchase.
Diamonds shapes are usually mistaken with diamond cuts. Diamond cut give insights on the proportions of the diamond which decides its brilliance, fire and scintillation while diamond shape refers to the geometrical outline of the stone.
Most diamonds are found in nature with a hint of yellow or brown. Typically a diamonds value is directly proportional to its colourlessness but on the other hand fancy coloured diamonds can be extremely expensive as well. The current diamond grading scale was developed by Gemological Institute of America (GIA).
D,E,F – Colourless face up and face down
G,H,I,J – Colourless face up, nearly colourless face down
K,L,M – Faint yellow face up, faint yellow face down
The GIA grades diamonds from D to Z in terms of how colourless a diamonds is.Grade D being the most colourless and Z containing noticeable brown or yellow tint.As a general rule of thumb, diamonds colour based on the grading system can be considered as follows:
N,O,P,Q,R – Very light yellow face up and face down
S,T,U,V,W, X, Y,Z – Light yellow (substantial) colour face up or down
DIAMOND COLOR GRADES
A diamonds clarity evaluates how devoid a diamond is from blemishes and inclusions.Most diamonds are found with some “junk” inside them, which are referred in
- Size of inclusion
- Number of inclusions
- Position of inclusions
gemological terms as inclusions, scratches and other surface imperfections are called blemishes. Five clarity factors that determine the grade of a diamond are:
- Nature of inclusions
- Colour or relief of inclusions
THE DIAMOND CLARITY GRADES
|IF (Iternally Flawless)||IF (Iternally Flawless)||VVS1, VVS2 (Very, Very Slightly Included)||VS1, VS2 (Very, Slightly Included)||SI1,SI2 (Slightly Included)||1,I2,I3 (Included)|
|No inclusion and no blemishes visible under 10xm agnification.||No inclusions visible under 10x magnification||Inclusions so slight they are diffult for a skilled grader to see under 10x magnification.||Inclusion are observed with effort under 10x magnification,but can be characterized as minor||Inclusion are notcable under 10x magnification.||Inclusion are obvious under 10x magnification which may affect transpa rency and brilliance.|
A few misconceptions exists when it comes to diamond carat. Carat of a diamond is often mistaken for the size of the diamond but it actually refers to the weight of the diamond, likewise diamond carat is for weight and gold karat is for measuring the gold purity.
1 ct. = 1/5 gm. 1/100 ct. = 1 point
TAKING CARE OF DIAMOND JEWELLERY
While diamond’s may be the hardest stones known to man, diamonds are still prone to physical damages like cracking, chipping etc. Don’t let the diamond come in contact directly with hard surfaces. Avoid wearing diamond in adventure and sporting activities. When a diamond is worn over time, it can be become dull and less shiny. This
While there are various cleaning methods available for diamonds like ultrasonic cleaners, steam cleaners etc, diamonds can be cleaned easily with the help of lint-free cloths and mild detergents. The most easy way to clean a diamond effectively is by gently brushing the diamond in a bowl of warm water with mild detergent. Another
undesirable effect can be a result of dirt and oil residues originating from fingers or skin contact accumulating on the surface of the diamond. Even a thin film of oil or grease on the surface of a diamond’s facet will alter the properties of light inside the diamond and will affect its ability to sparkle.
method is by soaking the diamond in 1 cup warm water and 1/4 cup ammonia for 20 minutes and then rinse and leave to dry. There are also various diamond jewellery cleaners available in the market which can be effective as well.
When not worn, the most secure way to store a diamond jewelery is to store in the jewelery box itself. Never store diamond jeweleries together in a bag or box. Keep the jeweleries
in separate pouches to avoid damaging. Try to keep the diamond in a cool and dry place because excessive heat and moisture can damage the diamond.
