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.

Answers last updated July 2, 2026

Are lab-created sapphires and emeralds real gemstones?

Yes. Lab-created sapphires, rubies, and emeralds are chemically, physically, and optically identical to mined stones — the same corundum or beryl crystal with the same hardness and color. “Lab-created” means grown in a controlled environment, not an imitation like glass or cubic zirconia. Signora Jewels uses genuine lab-created gemstones in made-to-order pieces like the Heart Double Halo Gemstone Ring.

Do lab-created gemstones fade or change color over time?

No. The color of a lab-created sapphire, ruby, or emerald is intrinsic to the crystal itself, so it is chemically stable and will not fade, cloud, or shift over a lifetime of wear. The only caution is avoiding sudden extreme heat with emeralds. Normal daily wear, sunlight, and water will not change the color.

Are lab-created gemstones durable enough for everyday wear?

It depends on the stone. Lab-created sapphires and rubies are Mohs 9 — second only to diamond — and ideal for daily wear. Lab-created emeralds are Mohs 7.5–8: fine for regular wear, but choose protective settings like bezels or halos and remove them for rough work. Check each Signora Jewels listing for the stone’s specifics.

How can you tell if a sapphire is lab-created?

Not by eye — even a jeweler needs laboratory magnification to spot the curved growth lines that distinguish lab-created from natural sapphires. Lab stones are typically cleaner and more evenly colored than mined ones. Signora Jewels discloses stone origin on every listing, and our gemstone encyclopedia explains each stone in depth.

Are lab-created gemstones worth anything?

Honestly, lab-created gemstones resell for less than natural stones because supply isn’t limited — so buy them for beauty, not investment. In exchange you pay a fraction of the natural price for an identical-looking stone, which is why buyers choose larger, cleaner lab-created sapphires, rubies, and emeralds. Signora Jewels states stone origin plainly on every listing.

How do I clean lab-created gemstone jewelry?

Warm water, mild dish soap, and a soft brush clean lab-created sapphires, rubies, and emeralds safely — soak briefly, brush gently behind the stone, rinse, and pat dry. Skip ultrasonic and steam cleaners for emeralds. Remove gemstone jewelry before applying lotion or perfume, which leave a film that dulls the color — more in our care guide.
