Understand Your Diamond
Colorless, with minor traces of color only a trained eye can catch.
Color grades the natural tint in a diamond on a scale from D (colorless) to Z (heavily tinted). The closer to colorless, the rarer — and more valuable — the stone.
Inclusions extremely difficult to see under 10x magnification
Most diamonds carry tiny internal or surface imperfections. Clarity grades how visible those are, from Flawless (FL) down to Included (I3) — the rarer grades are hardest to find.
Outstanding brilliance and light return, cut to ideal proportions.
Cut grades how well a diamond's proportions and facets return light, from Ideal down to Poor. A well-cut stone shows more brilliance and sparkle, whatever its shape.

Measure an Existing Ring
- Select a ring that fits the intended finger seamlessly.
- Measure the exact inside diameter across the widest center point in millimeters.
- Match the millimeter measurement to our conversion chart.
Measure Finger Circumference
- Wrap a non-stretchy strip of paper snugly around the base of the finger.
- Mark the exact overlap point with a fine-tip pen.
- Lay the paper flat against a ruler and read the length in millimeters to find your circumference.
Master Jeweler Advice
Fingers expand slightly in warmer temperatures and towards evening. For accuracy, measure at room temperature when relaxed.
If your knuckle is noticeably larger than the base of your finger, measure both and choose a size midway between them.
When between sizes, we recommend selecting the larger size for bands wider than 4mm, and smaller for delicate solitaire settings.
