FAQ's

Answer

You will not. You need to be an expert and use specialised equipment to make sure a diamond is real. Do not trust ideas like scratching a beer bottle (it may damage the diamond too), thermal conductivity, looking through, comparing weight, etc. If the diamond is accompanied by a certificate, you will know it is real and if it is treated artificially or not.

Answer

Round brilliant diamond has the most brilliance, and the most popular. Fancy diamonds look more elegant in larger sizes. Also, they tend to look larger than they are by virtue of their shape. The choice of shape is also governed by the shape of the hand and Diamond Colour and Diamond Clarity. Round brilliant diamond hides defects and yellow tints the best.

Answer

Facet: any of the flat "sides" of the diamond. 2. Table: On a brilliant cut stone...the top octagonal facet 3. Girdle: The typically frosty white ring at the widest part. 4. Culet: The bottom point (actually a facet) on a brilliant cut stone 5. Pavilion: The portion of the stone below the girdle 6. Crown: The portion of the stone above the girdle 7. Diameter: Width of the diamond as measured thru the girdle 8. Fire: The quality of the diamond that breaks reflected light into a colourful array. 9. Depth – Height of Gemstone from Culet to Table 10. Brilliance: The quality of the diamond that reflects light without changing it (also called sparkle). 11. Fluorescence: The characteristic of some diamonds to fluoresce certain colours under some light. 12. Natural: Usually found on the girdle. A small section was on the side of the raw diamond. It appears as a slightly rough flat spot on the girdle. 13. Feather: A “crack” in a diamond, appears as a white feather within the stone.

Answer

The first six terms describe the geometry of the diamond. Fire and sparkle are variable characteristics that are determined by the proportions of the diamond. Modifying proportions to increase one may decrease the other! Look for a good balance of fire and sparkle. Fluorescence occurs naturally and synthetically. It is not common, so jewellers will try to command a higher price. In general, it does not change the value of the stone, but severe fluorescence gives stones an oily appearance in sunlight, and decreases its value. Naturals if not severe are not bad. Small feathers are common. Any crack that extends more than 1/3 of the way through the stone may cause structural problems.

Answer

On a brilliant full-cut stone, there are 58 facets; 32 facets plus the table above the girdle and 24 facets plus the culet below the girdle. Some stones with only 18 facets are refered to as "single cuts".

Answer

Use the search option on Caratlane that searches for loose diamonds and fill in your preferred budget details. You will get a range of stones that you can sort by size. Alternately, you can first enter the size of diamond you were considering (in case you do not want to buy anything less than a carat, for instance).You can choose your diamonds from CaratLane Colossal collection if the size does matter to you. Sort the search results to see which diamond in this size suits your budget.

Answer

Since diamonds are a natural substance, most come with some small internal flaws or inclusions that are like their defining characteristics, similar to birth marks. Completely flawless diamonds are extremely rare, and usually found only with collectors. For a good idea of the inclusions in a diamond, examine its certificate for a description of these. You need to have an idea of how the clarity of a diamond is measured, to understand the relative impact of black inclusions. For instance, diamond inclusions can be characterized as Slight, Very very slight etc. Visit the section on diamond clarity, for a better understanding of this.
