Ring size guide

Lay a ring you own flat on the circle and slide until it sits just inside it — or set its inner diameter directly.

Measure the inside of a ring that already fits — inner edge to edge — with a ruler in mm, then set it below. No ring handy? Try Measure your finger.

Between sizes? Always choose the larger size. Fingers are slightly bigger in the evening — measure then for the best fit.

Method 1 — Use an existing ring

Find a ring that fits the intended finger comfortably.
Place it flat and measure the inner diameter (inside edge to inside edge) in mm.
Enter that measurement in the Measure a ring tab.

Method 2 — Wrap and measure

Wrap a thin strip of paper around the base of your finger.
Mark where it overlaps — measure that length in mm (your circumference).
Divide by 3.1416 (π) to get your diameter, then use the Measure a ring tab.

Tip: Middle finger sizes typically run half a size larger than the ring finger. If between sizes, go up. Measure in the evening — fingers are slightly larger then.

At a glance

A round lab grown diamond side stone engagement ring from Signora Jewels.

Main diamond: 0.264 ct · Side diamonds: 0.210 ct · Total diamond weight: 0.474 ct.

The CAD uses 7 round diamonds: one 4.00 mm center and six 2.00 mm side diamonds.

The diamond-set top measures approximately 4.00 mm through the center, with a 3.00 mm setting profile, 1.80 mm upper band profile and 1.60 mm lower shank.

Signora Jewels puts a 4.00 mm round at the center, then steps the scale down immediately to six 2.00 mm rounds across the shoulders. The center weighs 0.264 ct, while three smaller diamonds on either side contribute another 0.210 ct. Small polished links separate the settings, so the stones read as individual points of light instead of one continuous pavé strip.

The complete seven-diamond layout weighs 0.474 ct. The lower half of the shank remains plain and polished, keeping the stonework concentrated across the top of the finger.

Design highlights

4.00 mm round center diamond weighing 0.264 ct
Six 2.00 mm round side diamonds totaling 0.210 ct
0.264 ct main + 0.210 ct sides = 0.474 ct total diamond weight
Seven round diamonds across the complete design
Individually prong-set side stones with open spacing between settings
Plain polished lower shank measuring approximately 1.60 mm in the CAD

The center is only twice the diameter of the smaller rounds, so the transition into the shoulders feels gradual rather than abrupt. Each side carries three 2.00 mm diamonds before the stonework gives way to the polished lower band.

About Lab Grown Diamonds

The CAD uses seven round diamonds at two sizes. The 4.00 mm center weighs 0.264 ct, while six 2.00 mm side diamonds total 0.210 ct. Together they bring the complete diamond weight to 0.474 ct.

Metal, Care & Fit

The CAD gives an 18K metal weight of 2.32 g. Because the side diamonds are individually set rather than buried in a continuous channel, their undersides remain accessible for cleaning. Use warm water, mild soap and a soft brush around the center basket and behind all six smaller rounds.

FAQ

What is the total diamond weight of this seven-stone ring?
The complete ring has 0.474 ct total diamond weight. The 0.264 ct center combines with six side diamonds totaling 0.210 ct.

How are the side diamonds arranged around the center?
Three 2.00 mm round diamonds sit on each side of the 4.00 mm center. The six smaller rounds total 0.210 ct and form a balanced graduated line across the top of the ring.

How does the center differ from the side stones?
The center measures 4.00 mm and weighs 0.264 ct, while each side diamond measures 2.00 mm. That size difference keeps the central round visibly dominant without breaking the continuous seven-stone composition.

How does this ring stack with another band?
The lower shank is plain and measures approximately 1.60 mm in the CAD. The raised center and individual side settings occupy the upper section, so the exact gap beside another band depends on that band's profile.

How should the seven diamond settings be cleaned?
Use warm water, mild soap and a soft brush from both the top and underside. Brush behind the center and each of the six 2.00 mm side diamonds, then rinse thoroughly.
