Fiery Multicolor Australian Opal Heart

This 3.72ct Natural Dark Opal Heart is a showpiece of vibrant Australian fire. Mined from Lightning Ridge and expertly polished into a smooth heart cabochon, this opal bursts with radiant flashes of fiery red, orange, gold, green, and deep violet, shimmering across a dark body tone that enhances its depth and dimension.

The symmetrical heart shape makes this opal especially desirable for fine jewelry, while its vivid multicolor fire makes it truly rare. Lightning Ridge dark opals are celebrated for their intensity, and this stone captures that reputation beautifully.

Ideal for designers looking to create a one-of-a-kind pendant or ring, this opal is equally suited for gemstone investors and collectors. Its natural origin, untreated purity, and full-spectrum color play make it a timeless treasure.

The best heart-shaped opals come from Opal Galaxy.

Features & Benefits:
Natural Dark Opal Ethically sourced and polished to perfection
Vivid Rainbow Fire Includes red, green, violet, gold, and orange hues
Heart-Shaped Cut Ideal for high-end jewelry or display
Rare & One-of-a-Kind A powerful collectors piece from Lightning Ridge
October Birthstone Believed to inspire emotional depth and creative energy

    They certainly look like Australian Opals and are exactly as described. My wife loves opals and I got her these for Christmas to make her own custom piece with.

    Beautifully packaged for delivery, and a lovely finish on a gorgeous stone. Very unusual pink and mint green/aqua pastel colours. Quite unique for opal, which is already always one of a kind. I love it! My only advice to other buyers buying opals on Etsy is to always read the item description haha. I’d planned this one to be the centrepiece for a bracelet or wrist cuff, but because I was so enamoured with the stones colours and patterns I didn’t even check the actual size and dimensions of it. Make no mistake, the seller had wonderful photos and a clear and accurate description of the stone. The mistake was all mine! It was just a lot smaller than I had imagined in my head, purely because I didn’t measure properly for my ideas - so it will now be a divine ring instead 😍 Would 100% buy from this seller again!

    I have bought several beautiful Australian opals from opalgalaxy and each one has been more beautiful than I ever could have expected. This will make a beautiful ring which I will have mounted in a shadow box type ring so the opal will be protected.

    I purchased it from Japan. Since the owner was also Japan people, we were able to communicate with him in the Japanese, and he answered questions before purchasing, so I was able to wait for the arrival with peace of mind. In addition, it arrived earlier than originally planned and was carefully packed. Opal is also satisfied with the very beautiful quality almost exactly as pictured! Thank you again if you have any transactions.

    This is so beautiful and delicate that I will be holding on to this set for a while. I will take a while for me the gain enough skill to attempt setting it. That's okay, because I still enjoy taking it out to look at it. I think I have a small cabochon that will match it nicely. If I can find a few more of different sizes I would have an amazing men's set. I think this would make a beautiful and subtle statement in a tie (slash) lapel pin which could also be worn as an ear ring if desired.
