6.72 Ct Boulder Opal Freeform Cabochon – Multicolor Fire on Dark Matrix
This 6.72 carat boulder opal displays vibrant flashes of blue, green, orange, and red across a dark ironstone matrix, creating strong contrast and eye-catching play-of-color.
The freeform cabochon cut follows the natural shape of the material, preserving the organic flow of color across the surface. Bright patches of color shift depending on lighting, with the strongest fire appearing in direct light.
Visible matrix patterning and natural inclusions are present, typical of boulder opal, adding depth and individuality to the stone. Fine surface-reaching features and natural lines can be seen under close inspection, consistent with this type of material.
This gemstone is well suited for a bold, one-of-a-kind jewelry design, especially as a pendant or statement ring where its natural pattern and color can take center stage.
Hand-selected for color and character by French Cut Gems.

Real experiences from our customers
My sisters and I love how special it is to have necklaces that match our mom's birthstones. We worked with Jeremiah to create custom pieces for all three of us. They came out beautiful and are so meaningful to us.
I received a lovely compliment on my necklace at card club yesterday and was so pleased to share that I had it custom-made through French Cut Gems. The whole experience was wonderful.
I bought a birthstone pendant for my wife and couldn't be happier. The stone was exactly as described and the quality exceeded my expectations. Will definitely shop here again.
