The Four C's of This Lab Diamond
Carat: 2.5ct
Carat is the weight of the diamond and contributes to the diamond's size. Use this printable guide to see what different size diamonds look like in real life.

Color: E
Color is the visible presence of color in a diamond and does not change over time. Color is measured on a scale of D to Z. Ada Diamonds only sells diamonds of color grades D, E, F, and G with half or our sales being D color (the best).

Clarity: VS1
A diamond's clarity refers to the presence of impurities or blemishes on and within the stone. Ada Diamonds only sells the top 4 clarity grades of VVS1 to VS2. IF may be available in rare cases. All diamonds sold by Ada are guaranteed to be eye clean.

Shape: Radiant

Radiant cut diamonds typically have 70 facets, compared to a round brilliant's 57, giving them extra sparkle and an icy appearance. At Ada Diamonds, we specialize in elongated radiants with length-to-width ratios of 1.35 - 1.45. We screen radiant cuts for empty paneling, bow ties, fish eyes, light leakage, and bulls-eye centers.
