4. Black Opals

Black opals are the most valuable and sought after opal. For over 45 years ODF have been fortunate enough to have worked with and cut some of Australia’s finest Lightning Ridge black opals.


Black opal is considered to be the most exclusive stone. Black opals naturally have a darker body tone, ranging from a dark grey semi-black appearing underbelly to a jet black tone. The naturally dark appearing under side of a stone effects the colour vibrancy present within an opal, making the stone appear brighter in colour and therefore higher in value. Along with the colour in the opal, other factors come into play when determining the overall value of a stone. The brightness and pattern in a black opal impact the stone value.

Black Opals are known for being mined in the town of Lightning Ridge, in northern New South Wales. Their distinct naturally dark body tone and often bright, vibrant colours have thought to be exclusive to Lightning Ridge but have also been discovered in Minitibie, South Australia.

When creating ODF doublets we only use gem quality solid opals. Our doublet opals are crafted using a fine slice of solid opal cemented onto a dark backing. Vibrant in colour, doublets are created to resemble solid black opals at a less of an expense. Both doublets and triplets are water sensitive, therefore stones should not be immersed.
