Drilled Boulder Opal Pendant

The Precision Drilling Process

Creating a drilled boulder opal pendant requires exceptional lapidary skill and a deep understanding of geological structures. Because the host ironstone is incredibly dense and hard, lapidary artists use specialized diamond tipped drill bits submerged in water to slowly carve a clean hole through the top of the piece. The artist must ensure they drill through the strongest part of the ironstone backing without compromising the vibrant color bar. The process is done before the opal is polished to avoid blow outs in the smooth face. Understanding the hardness of precious opals makes it clear why this technique is reserved only for solid boulder varieties and never fragile crystal opals.

Fixed Cord and Rope Options

To complement the raw and natural aesthetic of the drilled material, we secure each pendant with high quality earthy materials. Your pendant will arrive pre threaded and fixed with either an authentic adjustable Greek leather cord in black color or a highly durable adjustable wax rope in black color. Please note that these cords and ropes are permanently fixed to the pendants by our artisans and cannot be changed or swapped. Both options feature adjustable sliding knots, allowing you to easily lengthen or shorten the necklace to suit different necklines.

Minimalist and Organic Aesthetics

The primary appeal of a drilled pendant is its completely unobstructed view. Because there are no silver bezels or gold prongs covering the edges, the natural contours, undulations, and organic shape of the ironstone are fully displayed. This minimalist style highlights the stark, beautiful contrast between the dark brown matrix and the brilliant flashes of red, blue, and green color. Collectors who appreciate raw beauty often favor these pieces over traditional highly polished opal pendants.

Exceptional Everyday Durability

Boulder opal is uniquely suited for the drilled pendant style because the natural ironstone backing provides immense structural integrity. This solid rock foundation ensures that the drilled hole remains extremely strong and resistant to breaking under normal tension. To maintain the beautiful finish of both the opal and the attached leather or wax cord, you should simply wipe the piece with a soft cloth. Educational resources regarding natural minerals confirm that keeping the piece away from heavy soaking and chemical soaps will preserve its natural luster for years.
