Understanding Your Diamond
What makes your 1.20ct Round special — K colour, SI1 clarity, Excellent cut.
A visible warm, champagne-like tone. Stunning in vintage-style and yellow gold settings.
Noticeable under 10x magnification, but often still eye-clean — especially in brilliant-cut shapes that mask inclusions through sparkle.
The highest grade. Ideal proportions reflect nearly all light — maximum brilliance, fire, and sparkle. Only the top 3% earn this grade.
This 1.20 carat round measures 6.7 mm across. Carat refers to weight (1ct = 0.2g), not size — but the two are closely related. A 2ct diamond does not appear twice as large as 1ct, because weight distributes across all three dimensions.

Proportions
Deep. More weight is distributed vertically, which may reduce the face-up spread.
Larger table. Emphasises brilliance — strong, bright white light reflection.
