Jadeite Safety Coins 平安扣

Posted by All About Jade

Jadeite Safety Coins

Meaning of Safety Coins

Jade jewellery and ornaments can come in many different sizes and quality. They are often carved into intricate designs that symbolise different meanings especially important in Chinese culture. 平安扣 or safety coins, in direct translation, are usually worn for protection. Similar to the Chinese belief that jade bangles when worn dispel unfortunate events to the wearer, jade carved in the shape of a disc are also worn as a charm for the same effect.

Types of Safety Coins

Safety coins fashioned out of jade can come in a variety of shades and sizes. Even as jade, the coins can be either made of pure jadeite or even nephrite. The latter, displayed in the image below, will display a smooth matte finish typical of the softer nephrite material. A variety of colours can be found in different safety coins as well. This is typical of jadeite with its range of colours. Traditionally, jadeite safety coins have always been designed as pendants but with a modern take of jadeite jewellery, earrings designed as safety coins are gaining in popularity.

Value

Typical to jade jewellery, having a significant size of jadeite or nephrite material with excellent quality is extremely rare. Thus, jade safety coins with excellent quality are very highly valueable and are sought after by collectors as it is very difficult to find such pieces.

Quality of Jadeite - Translucency

Posted by All About Jade

Jadeite quality factors

Jade consists of two different materials, jadeite and nephrite, and is a term used to describe both materials. However, the physical properties of jadeite and nephrite are very different and thus, identification of quality in the two materials is also a very different exercise. Jadeite, in particular, has relatively clear discerning factors to look at in identifying its quality. One of the important factors affecting the quality of a jadeite would be translucency.

Translucency and Why It Matters

Translucency is a subset of transparency as a google search of its definition explains. It is the amount of light that can pass through an object. The more light can pass through, the more translucent the object is. In jadeite, the higher the translucency of a jadeite piece, the more valuable it is. Translucency is also a factor of how thin a jadeite piece is. As such, thinner pieces of jadeite which are clear and translucent, are valuable, however, they will pale in comparison to a thicker piece with similar translucency. The differences in prices are clearly evident as well. A completely clean and translucent jadeite piece of a considerable thickness will most likely be far more expensive than a thinner piece.

In grading terms, laboratory reports from Nanyang Gemological Institute (NGI), which certify jade pieces from All About Jade, classify colourless jadeite pieces broadly into 2 categories if they are translucent enough. The first being icy jadeite and this is a qualification of jadeite if it is of a high level of translucency. The second category is only offered to jadeite pieces that are extremely clear and translucent, and this is the glassy variety of jadeite. Both classifications are given only after laboratory testing of how light passes through the jadeite pieces. For non-colourless jadeites, the reports will indicate translucency in the remarks section of the report and similarly, only jadeite pieces with high levels of translucency are given these special remarks.

Icy Jadeite

Glassy Jadeite

Identification of the translucency of a jadeite piece is easy from a laboratory report. However, in cases where a jadeite piece, like a bangle, is large and has more material, laboratory reports can only indicate so much. Translucency in jadeite is rare. Only a very small percentage of jadeite pieces in the market have decent levels of translucency and their rarity directly correlates to their prices. In many cases, even if a portion of a jadeite bangle is translucent, the bangle will be worth much more than a more opaque piece of a similar colour.

Jadeite Cabochon Rings and Earrings

Jadeite Cabochons

Unlike most gemstones, Jadeite is not a transparent gemstone. As a result, Jadeite jewellery is not faceted like Sapphires or Rubies, and is fashioned into accessories with smooth surfaces. Colour being the prime factor for quality in Jadeite is followed by clarity of the material. Being generally known as an opaque material, Jadeite with high translucency is exceptionally rare. Fine grained Jadeite pieces found in raw stones will be carved to maximize the yield of the translucent material. When whole pieces of Jadeite that are completely translucent are found, cabochons can be fashioned out of the raw stone.

Colour and Quality

Jadeite cabochons can be found in numerous forms and typically, only exceptional material is carved into cabochons. They are graded by 3 main factors: Colour, translucency and size. As with all jadeite jewellery, green is the favoured colour and of the various green shades, a medium tone and highly saturated green is the most valuable. Another highly rare colour is the lavender jadeite. Translucency in jadeite is highly rare and a clear translucent jadeite cabochon would be an exceedingly rare and precious find. Lastly, rarity increases exponentially with size. However, having a large cabochon would affect the translucency of the material as light would have to pass through a larger cross sectional area of jadeite. Some examples of jadeite cabochons are shown below for reference.

Cabochons in Jewellery

Cabochons are typically fashioned into rings. In examples like the clear light green cabochon above, setting it as a ring is probably the closest one can get to wearing a bead of glassy water on one’s finger. Cabochon pairs are also sometimes set into earrings but to find a matching set of cabochons is not an easy task. Usually, pairs of cabochons are fashioned from a single piece of raw material. Like other gemstones, matching jadeite cabochons fetch a premium as a result.

At All About Jade, we have a selection of various jadeite cabochons either set into jewellery or as loose gemstones for a customized setting. As always, all our jadeite pieces are natural and unheated. To browse our selection of available jadeite cabochons, this is the direct link to our collection.

Jewellery Setting

Jewellery settings can be broadly categorized into two groups, settings for calibrated sizes and custom settings. Commercial gemstones, largely available in jewellery shops, are usually cut into pre-set dimensions that fit into standard moulds, uniformly used by jewellery setters. These gemstones which are cut into pre-set dimensions are also known as calibrated stones. This allows for a commercially efficient solution to jewellery setting, as a single mould can be used countless times to set different gemstones.

However, for more expensive gemstones, to cut a raw stone to conform to specific dimensions would mean that a large amount of material might potentially be lost. Finding a good piece of raw material is already a very different endeavour, finding a large sized raw material of good quality, is even harder. And thus, preservation of material is of utmost importance when cutting expensive and rare materials like exquisite rubies and sapphires.

Good quality jadeite is almost exclusively cut in custom dimensions. And settings for jadeite, similar to gemstones, can be done by skilled craftsmen honed in this art.

At All About Jade, most of our jadeite jewellery have been set into jewellery settings made out of 18K gold, be it yellow, rose or white gold. This allows for customers to forgo the hassle of having to design a custom setting and subsequently finding a craftsman to set the jewellery. Moreover, in most cases, finding a reliable craftsman, in Singapore, to perform a custom setting would be more expensive, considering how transactions usually lower in price with increased volume.

All our jewellery settings are performed by master craftsmen who have been working with us for countless years and if the need arises, custom designs and settings can be performed. The entire process of designing a custom setting to the delivery arrangements of the jadeite will be arranged by us. Advice on the optimum designs for any jadeite will also be provided either via email, or in person at our physical shop.

Our jadeite pieces are sourced as raw unset stones and will be sequentially arranged to be set into classic jewellery showcased in our physical and online shop. If there are any specific requests for a certain shade of green, or a certain size of jadeite cabochon pair for that dream pair of earrings, feel free to drop us a message to enquire or visit us at our physical shop to take a look at our custom jewellery settings in person. Odds are that we will be able to source a perfect piece for you from our inventory.

Imperial Green Jadeite?

Background

A wide variety of colours is available in jadeite. Of which, a specific shade of green is the most highly sought after variation. This particular shade of green is often described in many differing ways and a quick search online will lead you to various shades of green claiming to be the most exclusive. Apple green, vivid green and other names are common terms all leading to the most popular term, imperial green jadeite. However, noting the fact that there is no specific guideline to classify and grade natural jadeite, there is no actual clear definition of what constitutes an imperial green colour.

So, what is imperial green? To term imperial green as the most exclusive shade of colour for jadeite would naturally tag prices correspondingly. Thus, the most expensive jadeites should define the term imperial green.

Examples Of Some Really Expensive Jadeite

Some examples of the most expensive jadeite ever sold publicly are shown here.
