Buying Jewellery/ Membeli Perhiasan

nderstanding the Four C's is the first step in your journey to buying the perfect diamond. Many variations exist of the Four C's document but the overall content remains the same. I have prepared my own variation of the Four C's detailing the Cut, Clarity, Color and Carat you should look for and ,of course, the points to avoid.With the rarity of diamonds, and all diamonds are rare, it makes sense that gemstones that appear to be identical can show a wide range in value.To determine the relative worth of diamonds, you need to know your 4 C's of diamond buying :

Ever since I started the business I had my own ideas on how a diamond should look, to qualify for jewellery:
.
1. Color : a diamond should be more than just white but not necessarily Blue white

From the faintest yellow or brown to the very rare pinks, blues, greens and other colors (known as "fancies" in the trade) it is still no color at all that takes the cake when it comes to diamonds. A completely colorless diamond allows white light to pass through it effortlessly - dispersing it again as rainbows of color. Note:(In 1987 Sotheby's auctioned an approximately .95 ct. pink to purplish natural fancy color diamond and received $800,000 plus. Because of rarity.)
.
In Diamonds that are seen in the trade, most are near colorless to light yellowish. There are only about 25 impurity elements that effect diamond. In fact, 99.95% of all diamond is pure carbon. Some elements, that affect Diamond color, are:
nitrogen ... yellow
boron ... blue
crystal irregularities ... pinks, browns and reds
natural radiation ... green
Some diamonds are "fluorescent". Some even glow. This fluorescence is caused by the reaction between the light's energy and the diamond's atoms. Diamonds that fluoresce usually do so in blue.Fluorescence should be disclosed and explained when a diamond is being viewed. Remember slight to moderate fluorescence could be a means of identification.
.
2. Clarity : a diamond should be far better than just eye-clean but should not necessarily be Internally Flawless
.
In order to determine the clarity of a diamond, you'll need someone with a trained eye to view it under 10-power magnification. The majority of diamonds are born with miniscule "birthmarks" known as inclusions. The smaller and fewer the inclusions, the more able light can pass through the diamond, contributing significantly to its rare beauty. More than any other gemstone, diamonds are capable of producing the maximum amount of brilliance. Thus a diamond which is free of inclusions and surface blemishes is more rare and, by definition, more valuable.
.
A diamond's clarity can be affected by two types of flaws:
External flaws: these are any of the impurities that are on the surface of the diamond. External flaws are the result of wear and tear on the diamond or from damage caused during cutting.
.
Internal flaws: These are any of the many impurities that reside solely in the interior of the diamond. There are many kinds of internal flaws. A few important ones that you should familiarize yourself with are:
Black or dark spots: carbon or other dark spots.Clouds: Clouds, are microscopic inclusions that lower transparency.Fracture (feather) - the majority of imperfections in diamonds are the result of breakage in the diamond chemical structure.
