Buying a pearl necklace is an investment in a timeless piece of jewelry. Unlike other gemstones, pearls are organic and evaluated by a unique set of quality factors rather than a universal standard.

: Includes the main body color and secondary "shimmer" colors (overtones). Choose a shade that complements your skin tone.

Because there is no universal grading system, focus on these physical attributes:

: Perfectly round pearls are the rarest and most valuable. However, Baroque (irregular) shapes are popular for modern, artistic designs.

: Look for fewer blemishes, pits, or scratches. While minor irregularities are common in natural gems, cleaner surfaces command higher prices.

: Measured in millimeters (mm). A 1mm increase may seem small, but it can double the pearl's volume and significantly increase the price.

: Thicker nacre equals better durability and deeper luster.

: For a strand, pearls should be consistent in size, luster, and color throughout. A beginner's guide to buying pearl jewellery | Vogue India
