Start with your ring fit
Use a physical ring sizer on the intended hand and finger, at normal hand temperature. Choose a band that sits comfortably and passes the knuckle without painful pressure. A similar band width gives a more useful comparison; repeat at another time of day.
A round ring that already fits the same finger can give an estimate: measure straight across the inside opening in millimeters, excluding the metal band. Confirm uncertain or between-size results with a sizer or jeweler. Avoid string or paper, which can stretch or deform.
The selected product’s circumference takes priority over a general reference chart. The example below is the current Six-Prong Moissanite Solitaire Ring (FG-P0004), not a universal conversion chart.

Back to contents ↑Then compare stone size
Millimeters describe physical dimensions. Carat (ct) is a unit of weight, and DEW is a size comparison with diamond. These are separate measures. When a product uses ct as a supplier size label, it does not mean independently measured moissanite weight.
Swipe or scroll the table sideways if needed. All measurements keep their stated units.
| Supplier size label | Listed center diameter |
|---|---|
| 0.5 ct | 5 mm |
| 1 ct | 6.5 mm |
| 2 ct | 8 mm |
| 3 ct | 9 mm |
The existing FUGUI hand photograph compares round stones with 0.1–5.0 ct labels. It is a visual reference, not a 1:1 actual-size image or the exact photographed option for every product.
Screen size and zoom change displayed size. Oval, pear and other shapes have different outlines; a halo or accent stones can add to the whole setting’s coverage. Use the selected product’s written dimensions.
Necklaces: length and pendant are separate
Check the chain length and any extender separately from the stone or pendant dimensions. Wearing position depends on your proportions.
Swipe or scroll the table sideways if needed. All measurements keep their stated units.
| Measurement | Current stated specification |
|---|---|
| Chain | 45 cm + 5 cm extender |
| Main stone layout | 8 × 10 mm |
| Accent layout | 1 mm × 16 |
| Size label | 3 ct; supplier size label |
Check this necklace. The stone layout is not a measurement of the entire pendant or bail. Ask if you need an unlisted overall dimension.
Back to contents ↑Bracelets: check the listed length
Read bracelet length, width and any extender separately from stone size. If the needed dimension is not listed, ask before ordering instead of estimating from a photograph.
Swipe or scroll the table sideways if needed. All measurements keep their stated units.
| Length option (in) | Approximate cm as listed |
|---|---|
| 6 | 15.24 |
| 6.5 | 16.5 |
| 7 | 17.7 |
| 7.5 | 19 |
| 8 | 20.32 |
The cm values above preserve the product’s current option labels and rounding. They are not new measurements. Review bracelet options.
Back to contents ↑Earrings: check each stone and the selling unit
For the Eight-Prong Moissanite Stud Earrings (FG-P0046), one listed unit is one pair of two earrings. The size option describes each stone.
Swipe or scroll the table sideways if needed. All measurements keep their stated units.
| Supplier label (each) | Stone diameter (each) | Selling unit |
|---|---|---|
| 1 ct size | 6.5 mm | One pair (2 earrings) |
| 2 ct size | 8 mm | One pair (2 earrings) |
These are stone dimensions, not overall stud width, post length or setting height. View the earrings or ask about an unlisted dimension.
