What is the Atlas Standard? 

Unlike diamonds, pearl grading is not bound by a universal standard, which can sometimes make comparisons difficult. At Atlas Pearls, we pride ourselves on the trust we build with our customers by upholding grading practices that are clear, consistent, and transparent. Our commitment is not only to the beauty of each pearl, but to the satisfaction and confidence of every customer who treasures it.  

A comprehensive grading system is used by Atlas Pearls, as leading producer of South Sea pearls. This system evaluates various factors of each pearl, including size, shape, colour, lustre, and surface quality. By meticulously assessing these characteristics, Atlas pearls ensures that all pearls are graded accordingly. 

Our Process 

Once harvested from one of our eight pearl farms in the pristine waters of Indonesia, each pearl receives an initial grade from our farm teams. After the harvest is complete, the pearls are carefully transferred to our Head Office in Bali, where our expert graders begin a meticulous process. The pearls are first gently cleaned with a light tumble never treated preserving their natural beauty and integrity. Using specialised sieves, the team then separates the pearls by size before grading and parcelling them according to their other defining qualities. This process ensures that every Atlas pearl is celebrated for its unique character.

How are Pearls Graded? 

At Atlas Pearls, precision and expertise are at the heart of South Sea pearl grading. Each pearl is carefully examined by our skilled graders across a number of key qualities: 

Quality, How It’s Assessed, Typical Range / Categories 

Size:  Measured in millimetres, 8mm – 20mm (South Sea pearls are among the largest in the world) 

Shape: Categorised by overall form, Round (RD), Semi-Round (SR), Drop (DP), Short Drop (DS), Oval (OV), High Button (BH), Flat Button (BF), Baroque (BQ), Circle (CR), Keshi (KS), Necklace (NL) 

Colour: Evaluated by hue, tone, and saturation, White, Silver, Silver Mix, Coloured, Fancy, Gold, Light Gold. Atlas pearls specialise in producing White and Silver South Sea Pearls.  

Complexion: The complexion or skin of the pearl can vary from a clean flawless ‘A grade’ pearl, through to a ‘C grade’ pearl, which may have obvious spots or pits around a large part of the surface area.  

Lustre: Lustre refers to the inner glow or shine of the pearl that truly brings this ocean gem to life. It varies from pearl to pearl depending on the thickness and tightness of the layers of nacre that surround the pearl. Of these five variables that influence a pearl’s individual desirability, this is perhaps the most important. Atlas grading takes account of both skin complexion and lustre. 

Every pearl’s individuality is celebrated through this process, with grading designed to highlight its natural beauty and provide clarity and confidence for our customers.
