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.

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

Jade Si Dian Jin 四点金

Background

Si Dian Jin or 四点金, in Singapore is a gift that is presented from the family of the groom to the bride before a wedding. This tradition has its roots in Chinese culture and the types of jewellery presented as Si Dian Jin depends on the different dialect groups. The common Si Dian Jin set of jewellery presents itself as a set of a necklace, a ring, a bracelet or bangle and a pair of earrings.

Modern Take on Si Dian Jin 四点金

In most cases, Si Dian Jin, as a set of jewellery would be worn on the wedding day and subsequently kept in a safe to be passed down to future generations.

24k gold is usually the metal to go for when choosing Si Dian Jin due to its ability to retain value and absolute resistance to tarnish. However, as jewellery, 24k gold is not the hardiest and is susceptible to being deformed. Pure gold jewellery sets made in 24k gold are therefore not very practical to be worn more than the 1 occasion, before being tucked safely away in safe boxes. Thus, many places nowadays offer many different modern takes on Si Dian Jin to be sets of jewellery that can be both meaningful and yet worn on formal or classy occasions, still made of 24k gold but incorporating other hardier material in various designs.

Here at All About Jade, varying sets of jade have been carefully selected to present options to the traditional Si Dian Jin in the classiest forms of jade. Jade, in itself, is an exceptionally hard material and will withstand the test of time. In terms of value, quality jade pieces have always been the go to material of Chinese as investments through centuries past. Choosing a set of quality jade jewellery adorned in gold would be the definite step up in beauty, durability and if recent trends are an indication, even investment value.

Jade Bangles

Jade Bangle - Raw StonesJade bangles come in a multitude of variations. In general, jade bangles are the most common form of jade jewellery and are probably jade in their most recognizable form.

Due to its hollow circular shape, producing a single jade bangle would require a large piece of raw jade. As a result, quality jade bangles are much rarer as compared to other jade jewellery in other forms. Larger blocks of good quality jade are significantly much harder to find. As such, quality jade bangles also increase in price substantially with the increment in thickness of the bangle.

The image on the right illustrates how blocks of jade are selected for carving out jade bangles. Any single crack line on a block of jade will render the block unusable for carving jade bangles.

Different Types of Bangles

Material

Jade bangles, like all jade jewellery, can be firstly split into 2 main categories: Jadeite and nephrite bangles. Differences between jadeite and nephrite are fundamental and affect everything about the jade, from colour to lustre.

Colour

Jade bangles come in all sorts of colours. Since jade bangles need to be carved out from a single block of jade, finding good quality jade bangles with beautiful green shades are exceptionally rare. A sample of some of the colours available for jade bangles is shown here:

Jade Bangle - Colours

Shape

The shape of a bangle will determine the fit of a bangle worn on the wrist. There are 2 main shapes that jade bangles are designed in. Jade bangles are either oval in shape or circular in shape.

Round Shaped Jade Bangle Oval Shaped Jade Bangle
Jade Bangle - Round Shaped Jade Bangle - Oval Shape

Cut (Cross Sectional Dimensions)

Traditionally, bangles are cut and polished to be circular in both shape and cross sectional dimensions. This requires the most raw materials due to the bevels required to achieve the round cross sections. There have been introductions to jade design both out of practicality, functionality and perhaps style.

Today, jade bangles can mainly be found in 4 different kinds of cut: Rounded-square, round, inner bevelled and bevelled (outer and inner).

 Jade Bangles - Cross Sections

Bevelling the surface of the bangle allows for the removal of imperfections that would otherwise allow for a round bangle to be made. It also makes for a more comfortable fit if the bevelling is done on the inner side of the bangle. Having straight lines provides a cleaner silhouette and appeals to a more modern fit for an otherwise traditional form of jewellery.

Tips on Wearing Jade Bangles

Jade bangles typically have no opening mechanism built in, unlike bracelets. Thus, the fit of a jade bangle is very important. If a bangle is too large, the bangle might not necessarily fall off but this increases the incidences of accidentally hitting the jade bangle against objects, thereby causing it to break. If a bangle is too small, the act of wearing the bangle is actually impossible without breaking some bones. So, to choose and wear a good fitting jade bangle, some bearable pain has to be endured. Here are some tips to reduce the discomfort of squeezing one’s hands through a bangle and to wear a bangle that fits well on the wrist.

Lubricate

The easiest way to get a jade bangle into one’s hand is to use soap as a lubricant. Lubricating the hand and the jade bangle will reduce friction to allow the bangle to slip over the hand. Any sort of lubricant will help and using soap is beneficial since that also cleans the jade bangle at the same time.

Hand creams are another form of lubrication and are very useful in situations where soap and water are not available. Moreover, unlike pearls and coral, jade is not affected by creams or soap, allowing people to wear their bangles all the time even while bathing.

Using Plastic Bags

At most physical jade shops, the go-to method for trying out jade bangles would be to use a thin plastic bag. The plastic bag would be placed over the wearer’s hand before slipping the jade bangle over the wearer’s hand. The jade bangle will not be in contact with any skin and this works just like a lubricant. The benefit is that the wearer does not have to come into contact with any chemicals. A pictorial guide illustrating how this can be done can be found in the link here.

Getting A Friend To Help

Fitting into a jade bangle might not be the easiest thing to do. Even with considerable amounts of soap and water, sometimes, it is hard to squeeze into a jade bangle. Thus, having someone around to help out would be useful.

Bangle Sizing

Purchasing a bangle will depend highly on personal preferences due to the number of variations available for selection. However, to begin any selection, one should filter the available options by the size of one’s hands and wrist. Sizes of hands differ from person to person and this should be used to filter out the bangles that can be bought and worn comfortably (without breaking any bones).

Wearing a bangle involves squeezing ones hands to create the smallest circumference possible and slotting the hand through the bangle. Thus, to know the size of bangles that can be worn, one has to identify the minimum circumference of one’s squeezed hands. A pictorial illustration of measuring the minimum circumference can be seen from steps 4 – 8 of this link.

The minimum circumference of one’s hands depends greatly on the flexibility of one’s bones. Most jade bangles provide inner diameter specifications but not the circumference. Thus, as a guideline, using the calculation for circle circumferences, a table is provided below for quick reference.

Hand Circumference Minimum Bangle Diameter
157 - 163 mm 50 - 52 mm
163 - 170 mm 52 - 54 mm
170 - 176 mm 54 - 56 mm
176 - 182 mm 56 - 58 mm
182 - 188 mm 58 - 60 mm
188 - 195 mm 60 - 62 mm
195 - 201 mm 62 - 64 mm
201 - 207 mm 64 - 66 mm
207 - 214 mm 66 - 68 mm


The sizing guideline is calculated with the assumption that the jade bangle is of a circular shape and should only be taken as a reference. Whether one can wear a bigger size is dependent on one’s comfort level. A loose fitting jade bangle might feel insecure as it might drop off accidentally. Whether one can wear a smaller size, is really dependent on one’s ability to endure pain (It is quite painful to squeeze into a smaller sized bangle).

The only way to be perfectly sure that a jade bangle fits is to try out the bangle in person. The next best option is to purchase jade bangles identical to an existing jade bangle that fits. However, being able to fit into a round bangle of certain size does not necessary mean that one is still able to fit into an oval shaped jade bangle of the same size.

Buying Jade Bangles

An assortment of jade bangles can be purchased online and offline. However, if you wish to purchase a jade bangle for the first time and you are physically in Singapore, please do drop by at our physical shop, at 54 Smith Street, to understand the best fit for your hand. As much as we would like to be an online store, buying jade bangles is really quite a physical affair.
