Round and near-round pearls
Round pearls have the strongest symmetry requirement and normally cost more when luster and surface quality are equal. Near-round pearls show slight flattening or off-axis variation that may be difficult to notice in a finished strand. State the viewing distance and acceptable variation instead of relying only on the word round.
Button, oval, potato and rice shapes
Button pearls are useful for studs because their flatter profile sits closer to the ear. Oval and rice shapes create directional designs, while potato pearls offer an organic look at accessible price points. Confirm length, width and thickness ranges because a single diameter cannot describe these shapes.
Baroque and special forms
Baroque pearls are valued for individuality, but a commercial batch still needs a controlled design language. Specify whether you want softly irregular, elongated, coin, keshi-like or strongly sculptural pieces. Ask for representative photos across the full lot, not only the most attractive pearls.
How to write a shape specification
Record the trade shape name, measurable dimensions, allowed asymmetry, drilling direction, color range, luster level and intended product. For pairs, add matching tolerance. For strands, define whether gradual variation is acceptable. Keep the approved sample and its batch photos with the purchase order.
Choosing shape by product
Use button or compact near-round pearls for comfortable studs, calibrated round or near-round pearls for classic strands, and controlled baroque pearls for design-led pendants. Test the actual findings and drill direction before bulk production because shape changes how a pearl hangs and how much metal is visible.
Frequently asked questions
Which freshwater pearl shape is most expensive?
Well-matched round pearls usually command the highest price when size, luster, color and surface are comparable.
Are near-round pearls suitable for classic necklaces?
Yes. A well-matched near-round strand can look very classic while offering a more accessible cost than a strict round grade.
How should baroque shapes be approved?
Approve a representative sample range and batch photos that show typical, best and weakest pieces.
