Opal Laser Drill Holes: A Controversial Technique with Benefits and Drawbacks

Opal Laser Drill Holes: A Deep Dive into the Controversial Technique

Opals are one of the most fascinating gemstones in the world. With their captivating play of colors, they have been sought after for centuries and remain popular today. However, a controversial technique known as opal laser drilling has caused many debates among jewelers and gem enthusiasts.

In this panel discussion-style post, we will explore what opal laser drill holes are, their benefits and drawbacks, ethical concerns associated with them, and how to identify them when shopping for opals.

What Are Opal Laser Drill Holes?

Opal laser drill holes refer to tiny boreholes drilled into an opaque or heavily included opal using a high-powered laser beam. The purpose of drilling these holes is to remove unsightly inclusions that interfere with the stone’s play of color. By doing so, more light can enter the stone and reflect back out in spectacular flashes of color.

The process involves first identifying where the inclusion lies within the stone and then positioning it under a microscope-aided by lasers. The jeweler will then insert a fine wire-thin tube through which water flows to keep everything cool while drilling takes place. Once completed successfully, there should be no visible signs that any treatment has taken place other than perhaps some small pits on its surface close by where it was treated.

Benefits & Drawbacks

One major benefit of opal laser drill holes is that they make it possible to transform an otherwise dull-looking opal into something magnificent without having to cut away significant amounts of material from its surface. This means less wastage compared to traditional methods such as grinding or sanding down to remove blemishes.

Another advantage is that these drilled holes tend not only to brighten up an opaque or heavily included piece but also allow more light inside resulting in higher brilliance levels overall – thereby improving market value too!

However, there are several downsides to the technique. For one, drilling holes into a gemstone can permanently weaken it, resulting in potential breakage or cracking over time. The laser drill method also leaves behind tell-tale signs that the gem has been treated – something that purists and collectors would frown upon.

Ethical Concerns

There are various ethical issues associated with opal laser drilling that have sparked debates among industry experts and enthusiasts alike. One of these concerns is whether it’s morally right to alter a natural stone’s appearance artificially.

Some argue that by making such changes, we are robbing the opal of its inherent beauty while others believe it’s okay as long as there is full disclosure about the treatment involved so buyers can make informed decisions when purchasing.

Another concern is whether or not this process should be considered “enhancement” rather than “treatment.” Enhanced stones are often viewed as more valuable due to their improved appearance but may come at an unfair cost if they aren’t disclosed properly.

Identifying Opal Laser Drill Holes

When shopping for opals, it’s important to know how to identify those that have undergone laser drill treatment. While most drilled opals won’t show any visible signs of treatment on their surface, you can sometimes spot them under close examination using a loupe or microscope.

One common giveaway is tiny pits or dots on the surface near where the boreholes were made. If you see these marks on an otherwise perfect-looking stone, chances are high that they have undergone some form of laser drilling treatment.

Another way to identify lasered stones is by checking for fluorescence under UV light. Most naturally occurring opals will fluoresce brightly under UV light while those with drilled holes tend not to display much fluorescence at all due partly because impurities inclusions removed through this process-which typically fluoresce strongly-have now been removed from within them!

Conclusion

Opal laser drill holes remain controversial in many ways. While some argue that it’s a beneficial technique for enhancing the appearance of opals, others believe it alters their inherent natural beauty. Regardless of your stance on the issue, it’s essential to be able to identify laser-treated stones when shopping for opals.

Ultimately, what matters most is full disclosure and transparency in the gem trade so that buyers can make informed decisions about purchasing treated or untreated stones.
