Diamond Guide.

Brillant Stones

Visit Yanina & Co. in our private Diamond Room you will work with GIA Certified Diamond Graders who are extremely knowledgeable about diamonds. They will help you select from a wide variety of diamonds,from the most rare to the most cherished, all competitively priced. 

Diamonds are graded using a system commonly known as the Four C’s,judging the stone on its color, clarity, cut, and carat weight.

The difference between Lab Grown Diamonds & Mined Diamonds

Visually, there is no difference between Lab Grown Diamonds and Mined Diamonds. Even expertly trained gemologists cannot tell the difference. Lab Grown Diamonds are graded on the same scale as Mined diamonds, and are certified by the same leading companies as well, such as GIA and IGI. The biggest difference between the two diamonds? The price.

Lab Grown Diamonds benefit from groundbreaking technology, which has allowed scientists to recreate the same process that happens underground, in a lab! But instead of having to wait millions of years, they can now be produced within a year. Being able to work directly with the manufacturer, Yanina & Co. is able to secure some of the best pricing on these diamonds, with first round selection to their availability.

Lab Diamonds are graded by the same 4 C’s Mined diamonds are. They can have flaws and be imperfect. Just because they are created in a lab doesn’t make them any different than the stones we have been mining for centuries… except for not having to displace people, animals, and farmland. A cruelty-free and green production of diamonds, with a lower cost is now available, and we LOVE it. No need to worry about origin, low color or clarity grades. We can now have top of the line diamonds for affordable prices.


Diamonds are graded on a color scale established by the Gemological Institute of America (GIA). The grade ranges from D (colorless) to Z (heavily tinted). Truly colorless diamonds, graded D, are treasured for their rarity. Color differences are so subtle that only a highly skilled professional will detect any color in E or F stones. Even when a stone has a visible tint, such as K or above, it can still be very lovely if it has good clarity and cut. Warmer colored diamonds (K–Z) are particularly desirable when set in yellow gold. Icy winter whites (D–J) look stunning set in white gold or platinum. ​ Nature has also created diamonds in intense shades of blue, green, yellow, orange and pink — and red, which is rarest. These diamonds are called colored fancies, and the more intense the color, the greater their value. 


Almost all diamonds have slight imperfections, but for the most part, diamonds used in jewelry are clean to the naked eye. Flaws or inclusions can come in many forms. The fewer the flaws a diamond has, the more valuable it is. A diamond’s clarity rank ranges from IF (Flawless) to I3 (Included) based on the number, size, type and placement of its inclusions. ​ The greater a diamond’s clarity, the more brilliant, valuable and rare it is. Below is the GIA clarity scale, along with corresponding definitions for different clarity grades. ​

Cut & Shape.

Of the Four C’s, cut is the only characteristic that is completely controlled by man. Its also by far the most important factor in determining beauty. It may take nature to create a diamond’s special characteristics, but it takes a master cutter to reveal its true beauty. ​ Every diamond begins as a rough crystal. An excellent cut can make even a flawed diamond look brilliant, a poor cut can make even the most perfect diamond look dull, inferior and small.


In basic terms, carat weight is the weight of a diamond. One carat is equivalent to 100 points; so for example, a .75 carat diamond is 75 points. All things being equal, the more a diamond weighs the more valuable it is. ​ Diamonds can range in size from a fraction of a carat to several carats. The price per carat increases rapidly with size, and you can expect to pay a premium for stones that are above one carat weight. That’s why a single 2-carat diamond will cost substantially more than two 1-carat diamonds. In jewelry pieces with more than one diamond, the carats may be described in terms of total carat weight (TW). This is the combined total weight of all the diamonds in the piece.
