Gemstones
Pearls: Akoya, South Sea, Tahitian and Freshwater
Lustre, surface, shape, size and colour determine pearl value.
Types
Akoya (Japan, classic white), South Sea (large white and gold), Tahitian (dark, peacock tones) and freshwater (affordable, varied shapes).
The tooth test
Real pearls feel gritty when rubbed gently against the front teeth; imitations feel smooth.
