[dropcap size=small]O[/dropcap]nce the preserve of the Chinese elderly and souvenir shops peddling “exotic” treasures from the Far East, jade has a reputation for being dated and less glamorous than its sparkling gemstone cousins. But, as with most things in the luxury circuit, rarity breeds interest, and dwindling supply from Myanmar – which supplies over 70 per cent of world’s high-quality jadeite – has driven prices up.

In 2017, Christie’s sold a necklace composed of 29 jadeite beads with a ruby and diamond clasp for HK$95.7 million (S$16.6 million). Three years before that, a similar necklace made by Cartier and once owned by Woolworth heiress Barbara Hutton sold for US$27.4 million (S$37.1 million) at a Sotheby’s Hong Kong auction, breaking the record for the highest price ever paid for a jadeite jewel.

Such necklaces have simple designs because the stones themselves have a unique beauty. Its fine crystalline structure lets light dance through, reflecting and refracting rays in a way that makes its translucency look like water within the stone. And because of how jadeite forms in thin seams, it is immensely difficult to cut and polish identical sets of beads. Finding enough to make a string of homogeneous, flawless, vivid green beads is akin to finding natural pearls of the exact same size and shade.

Even on its own, jade is an enticing material for designers to work with.

It is tougher than rubies, diamonds and sapphires, so it won’t break when you try to carve into it, allowing jewellers to create intricate motifs and patterns. When paired with contemporary designs and settings, the result is a wearable piece of art that holds within it a pool of history.

What’s in a name?

It was French mineralogist Alexis Damour who, in 1863, categorised jade into two main types: jadeite and nephrite. Here’s how to distinguish the two.

Making the grade

According to Hong Kong jeweller Dickson Yewn, one can select jade either by emotional resonance or by the quality-price index of major dealers and auction houses. “This is the best way to learn about jade’s quality,” he says. If you’re leaning toward the latter, here’s a primer to get you started.


The jade has not undergone any form of artificial treatment to enhance its appearance or durability, except for surface waxing. Type A green jadeite with almost glowing translucency is the most valuable, and is known as “imperial jade”.


Slightly stained jade may be bleached or exposed to acid treatment to remove impurities and improve the colour and translucency. Because the texture of the jade gets damaged during the process, the gaps are filled with a clear polymer resin. Infrared spectroscopy will be able to detect the presence of polymer.


Chemically bleached or dyed to enhance the colour of green, lavender, yellow or red jade. If not done properly, the stone may wind up a dull brown. Regardless, Type C jade has a tendency to discolour over time if exposed to strong light, body heat or household detergent.


Basically a combination of the processes involved in creating Type B and C jade, where the stone is both impregnated with resin and artificially dyed.


The most inferior grade can be jade that is as thin as a piece of paper, but backed with resin to enhance its colour and transparency. If very little jade is used, it is mounted on a plastic backing.
