Understand the outline
Pearl shapes explained
Pearl shape describes the outline: round, near-round, oval, button, drop, or irregular baroque. Circled pearls have ring-like growth features and may also have another overall shape. Shape does not identify the mollusk, treatment or formation method.

| Word | What to look for | Buying question |
|---|---|---|
| Round / near-round | Overall symmetry | Can I see several angles? |
| Button | Flattened profile | How high does it sit in the setting? |
| Drop / oval | Elongated shape | What are the width and length? |
| Circled | Rings around the surface | Are rings part of the intended design? |
| Baroque | Irregular outline | Is the pictured pearl the one supplied? |
Round and near-round
A round appearance is not an authenticity test. Ask for views from more than one angle: a pearl that looks circular face-on may be flattened at the back. Assess an earring pair together.
A preference for rounds may increase the cost of a well-matched strand, but it should not override the luster or color you want. Near-round pearls can provide a similar impression when worn.
Buttons, drops and ovals in jewelry
A button's flattened back can suit a stud setting. A drop can work well in a pendant, but ask where it is drilled and how it hangs. For asymmetrical earrings, check whether the design is intentionally mismatched.
Measure non-round pearls in more than one direction. A single longest dimension is not comparable with the diameter of a round pearl.
Baroque does not mean keshi
Baroque describes an irregular shape. Keshi concerns non-bead cultured formation. A pearl can be both, but an irregular bead-cultured pearl is not thereby keshi. Freshwater, Akoya, Tahitian and South Sea pearls can all have irregular outlines.
Frequently asked questions
Are baroque pearls lower quality?
Shape is one factor. An irregular pearl can have attractive luster, color and surface; evaluate those separately.
Do rings around a pearl mean it is dyed?
No. Growth rings are not proof of dye. Color treatment requires separate assessment.

Non-bead cultured pearls can contain organic-rich cores; all nacre is an oversimplification.
