Unveiling the Factors That Influence the Cost of Gemstone Cutting in Australia

What factors do you think influence the cost of gemstone cutting? Several elements play a role in determining the overall price charged by gemstone cutting specialists in Australia. These include:

Gemstone Type

The type of gemstone itself is a major cost driver. Some gemstones like diamonds and sapphires are extremely hard, requiring more time, tools, expertise and precision to cut and facet compared to softer stones like opal or turquoise. The rarity and value of the material also impacts cost. Precious gemstones like emeralds command higher cutting prices than semi-precious or common materials.


Larger gemstones require more intensive work to cut, and will incur higher fees from the gem cutter. The cutting cost per carat often declines for very large stones above 10 carats. However, a 1 carat sapphire will be less expensive to cut than a 5 carat sapphire of similar quality.

Complexity of Cut

A basic round or oval brilliant cut is simpler and therefore less expensive compared to a more detailed emerald or asscher cut, which require greater mastery and care on the part of the gem cutter. The number of facets and intricate patterning can increase effort and thus costs. Fancy cuts like marquise or pear shapes take more preparation and expertise as well.


The clarity, color and carat of the material impacts the cutting cost. Higher quality gems command a higher price to cut because of their potential value and the lower margin for error. Inclusions, fractures or soft spots in lower grade materials require more cautious handling.


The geographic source of some gemstones like Australian opals or sapphires can influence perceived value and cutting costs. Local gems may have a premium over imported materials.

Cutting Service Level

From large factories to boutique workshops, the brand reputation, experience and capabilities of the lapidary service makes a difference. High end specialists charge higher prices for their expertise and quality assurance. Full service vs rough cutting only also impacts costs.

So in summary, the harder, larger, more complex and higher quality the gemstone, and the more skill required by the cutting service, the greater the expense to the client. Local gems by master cutters fetch premium prices. Understanding these factors helps manage expectations when investing in a custom gemstone cutting project.

Delving into the Gemstone Cutting Process in Australia

Are you curious about how gemstones are cut? Transforming a rough gemstone into a dazzling faceted stone is a meticulous process requiring skill, care and the right equipment. Here is an overview of the typical gemstone cutting stages in Australia:


The cutter will assess the rough stone and determine the optimal cut to maximize carat weight, quality and beauty. The plan accounts for the gem's shape, inclusions, color, and other factors. Complex designs require detailed planning to maximize value.


Guidelines are marked on the surface to map out the intended cut and facet placement. This may involve painting lines or placing adhesive dots. Precision is vital so the facets align correctly.

Cleaving or Sawing

The rough gem is carefully cleaved or sawn along the marked lines to separate pieces for individual cutting. Diamonds in particular are cleaved to take advantage of natural cleavage planes. Sapphires and other gems are typically sawn into workable sections.

Grinding and Shaping

Using a faceting machine with rotating abrasive discs or belts, the gemstone is ground to remove excess material and begin forming basic facets and shape. Progressive finer grits refine the form.


Final facets are precisely cut and polished on the faces of the gem using the faceting machine to create the planned pattern. The angles and alignment must be exact to maximize light refraction and beauty.


The gem is polished using fine abrasives to smooth out any minute lines or surface flaws from prior steps. Vibrating laps help polish difficult concave facets. This results in a brilliant lustrous finish.


The completed gem is meticulously inspected to ensure quality of cut, symmetry, and that it matches the planned design. Adjustments are made if required. It may also go through certification grading.

The finished cut gem is ready to be set into jewelry or sold loose. Each step requires care, skill and the proper tools to maximize a gem's inherent beauty and value through cutting.
