Diamonds 4CS


The "carob" seed, which served as the first unit of measurement for diamond sellers, gave its name to "carat."

Although most people think of a carat (represented as ct.) in terms of size, it is actually a measure of weight.

A carat weights 0.2 grams precisely.

The similar-sounding term karat, which denotes the purity of gold, is unrelated to carat weight.

With increasing size, the cost per carat does not rise linearly due to the rarity of bigger rough gems.

The single biggest advantage of shopping your diamond jewelry on Lotando is that, thanks to our elimination of middle-men, you can buy up to a 40% bigger diamond on your jewel than anywhere else for the same budget.


When it comes to white diamonds, color really refers to the lack of color.

The more colorless the stone is, the more expensive and sought-after it is.

Even though some of these variations cannot be seen with the naked eye, they have a noticeable effect on the stone's general quality and cost.

At Lotando, because you purchase your diamond / jewel directly from the manufactures, we are able to offer only the best diamond colors (D - J) and you still save a lot compare to normal market conditions.

A diamond's inclusions, which are natural internal flaws, are measured in terms of clarity.

The clarity of a diamond can vary depending on the size, color, relative placement, orientation, and visibility of inclusions.
Systems for grading clarity are based on the inclusions that can be seen by a skilled expert when a diamond is seen under a 10x magnification.

Only around 20% of all mined diamonds have a clarity level that is high enough to be regarded suitable for usage as a gemstone.

With better clarity gradings, diamonds become more and more expensive.

For the same reasons as for carat and color, we decided to limit our offer in terms of clarity only to the higher grades (F - SI2) because we are confident you will prefer a cleaner stone for the same price than what you can find elsewhere.


The cut of a diamond describes the manner in which a diamond has been shaped and polished from its original form as a rough stone to its final gem proportions.

It refers to the quality of workmanship and the angles to which a diamond is cut.

The techniques for cutting diamonds have been developed over hundreds of years, with the greatest achievements made in 1919 by mathematician and gem enthusiast Marcel Tolkowsky.

He developed the round brilliant cut by calculating the ideal shape to return and scatter light when a diamond is viewed from above.
The modern round brilliant has 57 facets.

Other notable improvements are an exceptional 88 facets diamond with an Excellent light reflection that the founder and CEO of Lotando sold exclusively to Cartier to use as their own branded diamond as well as a unique 101 facets diamond that was sold to Van Cleef and Arpels to celebrate the New Millenium.

Of course, at Lotando, we only offer you the best diamond cuts as we limit our range to the only ones that truly reflect light in a significant manner (Excellent - Good).
