At Johnston Opals, we take pride in offering a wide selection of Australian black opal stones, known for their rich colour, vibrant play-of-colour and premium quality. Our stones are available in a range of shapes and sizes, making them perfect for creating custom jewellery pieces. Whether you're a jeweller seeking unique black opal stone for your next creation or an enthusiast searching for the perfect gem for black opal jewellery, our collection ensures you’ll find the right black opal in Melbourne to suit your vision.
Choose from Various Black Opal Stone Shapes
Black opals are incredibly versatile, and at Johnston Opals, we offer stones in a variety of shapes to suit any design style. Whether you're looking for symmetry, elegance or something one-of-a-kind, our range includes expertly cut stones ready for setting in rings, necklaces, earrings or bespoke designs. Here’s a closer look at the most popular shapes we offer:
Round
Round black opals are timeless and classic. Their symmetrical form makes them a favourite for creating balanced and elegant jewellery pieces. Because of their even shape, they display the opal's play-of-colour beautifully from every angle. Round opals are especially popular in rings and stud earrings, with the symmetry enhancing their visual appeal. At Johnston Opals, our round stones range from petite to statement sizes, ideal for minimalist or bold designs alike. These gems are carefully cut to maximise brilliance, with their perfectly rounded silhouette making them a highly sought-after choice whether you’re after stunning black opal earrings or a unique black opal ring in Australia.
Oval
Oval black opals are a staple in jewellery design due to their graceful proportions and versatile nature. Their elongated form allows more surface area to showcase the opal’s stunning colour flashes and internal fire. Oval stones work beautifully in rings, pendants and brooches, offering a flattering shape that complements many styles. At Johnston Opals, our oval stones come in a variety of dimensions, from narrow and sleek to wide and bold, making them suitable for a range of aesthetic preferences. Their smooth curves and balanced appearance give them an air of sophistication and make them one of our best-selling black opal stone cuts.
Teardrop
Teardrop-shaped black opals are a dramatic and elegant option. Also known as pear-shaped, this form combines the best of round and oval shapes, resulting in a gemstone that feels both organic and refined. Teardrop opals are often used in pendant necklaces and drop earrings, where their shape naturally draws the eye downward, elongating the neckline or face. At Johnston Opals, we hand-select each teardrop opal to ensure a beautiful balance between shape and colour play.
Irregularly Shaped
For those seeking something truly unique, our irregularly shaped Australian black opal stones offer endless creative possibilities. These freeform stones highlight the natural beauty of opal without adhering to traditional symmetry. Often used for bespoke or artistic jewellery designs, irregular opals are perfect for one-of-a-kind rings, pendants or statement pieces. No two stones are the same, and their unusual contours often enhance the gem’s internal fire and colour movement. At Johnston Opals, we celebrate the individuality of these natural shapes and carefully curate our range to inspire innovative black opal jewellery.
The Beauty & Appeal of Black Opals
Black opals are renowned worldwide for their beauty and rarity. Their dark body tone enhances the vibrancy of their colour play, producing striking flashes of red, green, blue and violet. Unlike other opals, black opal stone displays intense, layered colours that seem to dance beneath the surface, making each stone a miniature masterpiece. Australian black opal in particular is considered the finest in the world due to its exceptional quality and striking appearance. Whether set in gold, silver or platinum, black opals add a dramatic and luxurious touch to any jewellery piece.
