Description

VERY RARE dark tru dark base no treatments dark base crystal welo. Cut from a 28ct rough by me. The rough was dry for 2 years before cutting has been vigorously longevity tested.

. Weather tested threw 98 degrees heat.

. Weather tested in below freezing conditions. No signs of internal or external damages.

. Hardness tested dropped multiple times by accident onto concrete. With no chips or cracks. I do mean multiple times. Also during cutting shot out of my hand flew into brick wall and onto concrete floor. Unscathed.

. Cut 4 years ago with no signs of internal or external damage.

. Master cut to show the tri tones evenly and perfectly centered.

. After cut it went threw the same multiple test for longevity.

. Also dropped again on concrete unscathed.

. The internal silica strands must be perfect.

. TOTAL OF 6 YEARS DRY...

. Same level as Australian opal of non hydrophane plus durability.

If you want this certified for proof of treatments plus proof of dark base crystal welo opal I will have to have a deposit. The value will also raise to $10,000+.

. This opal will come with a guarantee water will not phase it. It is non hydrophane. It will not fall apart nor craze or crack after long usage.

. This is a true collectors dream. Mostly all crystal opal of this size always crates and cracks during cutting not only cutting normal after a few months of being dry. It cracks, crates, or crumbles.

. Has a ribbon pattern with a full spectrum of color.

. Feel free to make me a offer you never know what I might exempt that day. Might not come down.

. After certified the value of this stone could reach $25,000
