Learn Diamond Criteria and Shapes | Know How to Buy Diamonds
We know that buying a diamond can be an emotional experience. At Lux Jewels in Vancouver BC Canada we’ll make you feel comfortable by helping you learn how to make the right decision for yourself – a decision you’ll feel comfortable with for many years to come.
There's a lot more to buying a diamond than the four C’s: cut, clarity, colour and carat. Other criteria include ratios for the fancy diamonds, depth, table and several other issues most diamond stores don’t even mention. They simply don’t equip their clients to assess the advanced criteria for selecting diamonds.
At Lux Jewels we examine ALL of the diamond criteria to determine which diamond to select for your jewelry and we always use conflict free diamonds.

Diamond Criteria | Know How to Buy Diamonds
Because diamonds are so valuable, it's essential to have a universal grading system for comparing diamond quality. In the 1940's and '50's, GIA developed the 4Cs and the GIA International Diamond Grading System™ to objectively compare and evaluate diamonds.
In selecting a diamond, the rarity, value and beauty are determined by four factors called the 4C's: Carat Weight, Colour, Clarity, and Cut (proportions & finish). Today, many consumers are aware of the 4C's. However, understanding how they determine value is important to discover what appeals to you in selecting a diamond and getting the most for your money.
Carat Weight | Diamond Criteria | Know How to Buy
Carat weight refers to the size of the diamond. Based on a standard unit of measure, one carat is divided into 100 points. The term originated from carob seeds that were used to balance scales in ancient times.
Colour | Diamond Criteria | Know How to Buy
The most desirable diamonds are colourless because the absence of colour enhances the diamond's ability to reflect a rainbow of colour. Diamonds are graded on a colour scale of D (white) to Z.
Clarity | Diamond Criteria | Know How to Buy
Diamonds can contain slight imperfections. Often invisible to the naked eye, these natural birthmarks fall into two categories - inclusions (internal) and blemishes (external). Fewer inclusions increase the value of the stone.
Cut | Diamond Criteria | Know How to Buy
Cut gives the diamond its brilliance. Of the four C's, it's the only one dependent on a human touch. Using precise mathematical formulas, the cutter can transform a diamond in the rough into a sparkling jewel that reflects and refracts light.
Diamond Shapes | Know How to Buy Diamonds
Most people who receive diamonds as a gift or for an engagement have a shape preference. While the purchaser should determine other factors such as price and quality, the choice of shape should include input from the recipient of the diamond, if at all possible. This is especially true for fancy shape engagement diamonds.

This is a square or rectangular cut with numerous sparkling facets. It is a relatively new cut and often finds its way into solitaire engagement rings. Flattering to a hand with long fingers, it is often embellished with triangular stones at its sides.
