When it comes to buying an authentic diamond, understanding quality & purity is the key

At CALYSTA, we want to make sure our partorns have all the valid information they need to make an informed decision.

Diamond Color

Diamonds are graded for color on a scal from D (coloriess) to Z ( Light yellow/brown). the less color a diamond has, the more valueable is.
D,E,F: Colorless. These diamonds have no detectable color and are hte rarest and most valuable.
G, H, I J : Near-Colorless. These diamonds may have a hint of color, but it is not usally visible to the naked eye. They are a popular choice for engagment rings because they offer a balance between quality and value.
K, L, M : Faint yellow. These diamonds have a noticeable yellow tint, especially when viewed from the side. They are generally less expensive than higher color grades.

Diamond Clarity

Flawless (FL) and Internally Flawless (IF) :Diamonds with no visible inclusions or blemishes under 10x magnification, making them very rare and valuable.
Very, Very Slightly Included (VVSa and VVS2):Diamonds with tiny inclusions that are difficult to see under 10x magnification, making them very high quality and valuable.
Very Slightly Included (VS1 and VS2):Diamonds with small inclusions that are visible under 10x magnification, but are not usually visible to the naked eye. These diamonds offer a good balance of quality and value.
Slightly Included (Sla and SI2):Diamonds with noticeable inclusions that are easily visible under 10x magnification, and may be visible to the naked eye. These diamonds can be a good value for those who want a larger diamond at a lower cost.
Included (11, 12, and 13):Diamonds with obvious inclusions that are visible to the naked eye and can affect the diamond's beauty and durability. These diamonds are generally less expensive.

In summary, the key difference between I-J-Sl and I-Sl1 (solitaire) and F-G-VVS and F-VVS2 (solitaire) is that the latter offers a higher level of quality and precision in both colour and clarity.
