In order to further provide comprehensive information for customers and enhance the transparency of product quality, Lukfook Jewellery now provides a GIA (Gemological Institute of America) Cultured Pearl Classification Report issued by GIA for selected pearl items to offer customers more comprehensive information on evaluating the quality of pearls when purchasing jewellery and enhance customers’ confidence. It is the first jewellery retailer in Hong Kong to launch the GIA Cultured Pearl Classification Report.

The GIA Cultured Pearl Classification Report is a detailed report that provides classification information on unmodified cultured pearls. This report includes a detailed classification of pearl(s) based on the GIA 7 Pearl Value Factors™ (Size, Shape, Color, Luster, Surface Quality, Nacre and Matching) as well as a digital image of the pearl(s) for identification. It is specifically and exclusively for the three major types of cultured pearls (Akoya, South Sea and Tahitian pearls).

GIA 7 Pearl Value Factors™ Introduction:

• Size: Stated in millimeters, to two decimal places.
• Shape: Described as round, near-round, oval, button, drop, semi-baroque or baroque.

• Color: A combination of the pearl’s dominant body color, overtone, and orient.
• Luster: The light reflected from or near the pearl’s surface, evaluated by the intensity and the sharpness of reflection.

• Surface Quality: Blemishes or irregularities confined to the pearl’s surface, taking into account the size, number, nature, location, visibility, and type of surface characteristics.
• Nacre: Nacre quality is the condition of a pearl’s nacreous surface. Nacre quality is related to nacre layering during a pearl’s growth, and it affects luster, surface, and durability.

• Matching: The uniformity of appearance in strands and multiple pearl groups or items.
