I1, I2 & I3

Flawless FL internally flawless IF

Diamonds that are Internally Flawless (IF) diamonds may contain external blemishes that are extremely difficult to view at 10x magnification. On the other side, Flawless (FL) is considered to be the best clarity a diamond can get, with no imperfections whatsoever.

Very Very slightly included VVS1 VVS2

Very Very Slightly Included (VVS1, VVS2) diamonds contain inclusions that are so minute that they're extremely difficult to locate under 10x magnification.

Very slightly included VS1 VS2

VS1 and VS2 diamonds also contain minute inclusions, but, unlike Very Very Slightly Included diamonds, the inclusions can be locate with more ease. 

Slightly included SI1, SI2, SI3

Slightly Included diamonds (SI1, SI2, SI3) contain inclusions that are noticiable to the human eye.

SI1-SI2 diamonds will contain inclusions that can be detected with magnification, yet are usually imperceptible to the naked eye and don’t bring down the excellence of the diamond / jewel.

Included I1, I2, I3

Included (I1, I2, I3) diamonds contain very obvious inclusions that can usually be seen with the naked eye.

Upon request, on some items, it is possible to choose different color and clarity than the ones used for all our items. Prices and details upon request.

 

Diamond shapes and cuts

Diamond shape is the outline and form of a diamond after it has been cut and polished. 

One of the most defining characteristics of a diamond is its cut and it determines its brilliance. Even a flawless diamond will appear dull if the cut is poor.

 

Shallow-Cut Diamonds

A shallow cut diamond allows light to escape from its sides instead of reflecting off its top.

Ideal-Cut Diamonds

Lumi Grade

This premier cut style is well-proportioned and carefully angled to achieve a luminous appearance.

Deep-Cut Diamonds

A diamond whose cut is too deep will look smaller than diamonds of similar carat weight.

Light’s Effect

There are many factors that effect a diamond’s brilliance, the most important of which is its ability to reflect light. As a light source passes through a diamond, tiny flashes will be visible within the stone.

Reflection

When light enters the surface of a diamond, a portion of it is reflected back out of the table (top).

Refraction

The remaining rays of light travel into the centre of the diamond and bounce off its internal walls.

Dispersion

A diamond whose cut is too deep will look smaller than diamonds of similar carat weight.

Cut Grade

The Cut Grade of diamond directly impacts its magnificence. When a diamond is cut and finished in an appropriate way, its appearance will look more attractive, also in comparison with diamonds of better color grade and clarity.

Diamond Carat Size

There are four C’s that are used to describe a diamond: cut, color, clarity, and carat. The carat is the standard unit of measurement used to indicate the weight of diamonds and precious gemstones. One carat equals to 0.2 grams or 0.007 ounces. 

The rarity of larger, high-quality diamonds has resulted in great price escalations between different diamond sizes. The carat weight is a measurement of the diamond’s weight, not of the diamond size. Diamonds that have similar or same carat weight can fluctuate in size depending on how they are cut.

The carat weight is not the only factor that affects the diamond’s appearance and perceived size. The shape of a diamond may impact as well. Diamond shapes cut at lower depths will have larger lengths and widths. Some shapes such as oval or marquise diamonds are elongated so they look larger in size than other shapes with the same carat weight.  Furthermore, emerald cut diamonds also look larger than their actual size due to their shape. Other shapes (princess or round for example), are not elongated, so they may not appear as large in comparison to others.
