This small cabinet sized specimen is beautiful association piece features a good sized, sharp, lustrous, beautiful blue-green colored, well-formed single crystals of Datolite measuring 6.2 cm, sitting atop satiny, colorless, gemmy/translucent twinned crystals of Calcite, with no matrix from the famed Bor Pit in Dalnegorsk.

The vast majority of the specimen is damage free, and even the edges of the Datolite where you see a slight subsurface deposition that which might appear to be broken at first glance are actually re-crystallized ("re-healed") and some areas show a slight secondary overgrowth, but I can't find any actual damage to the Datolite itself.

The only point of contact is on the base of the Calcite where the piece was removed from the pocket wall. This is one of those pieces you need to see in person to best appreciate the quality, and impressive size of the Datolite. Dalnegorsk Datolites don't get the credit they deserve as some of the finest examples of the species ever found. I don't think anywhere else in the world can rival the quantity and quality of Datolite that have come out of this area in the last 30+ years.

PPROXIMATE SIZE: 9.3 x 7.3 x 6.9 cm

Datolite on Calcite is a beautiful mineral combination that consists of datolite crystals growing on a matrix of white calcite. The specimens are found in several locations around the world, including Russia, where they are highly valued by mineral collectors and enthusiasts. Datolite is a calcium borosilicate mineral that is typically found in metamorphic rocks. It has a vitreous to greasy luster and ranges in color from white to yellow, brown, and green.

Datolite crystals are commonly transparent to translucent and often occur in aggregates or clusters. Calcite is a carbonate mineral that is found in many geological environments, including sedimentary rocks, metamorphic rocks, and igneous rocks. It is commonly white, but can also be found in shades of gray, yellow, green, blue, and orange. Calcite crystals are typically transparent to translucent and have a vitreous to resinous luster.

When datolite crystals grow on a matrix of calcite, the result is a stunning mineral specimen that showcases the contrasting colors and textures of both minerals. The datolite crystals are often elongated and can reach lengths of several centimeters, while the calcite matrix provides a backdrop of bright white or pale yellow.

Specimens of Datolite on Calcite from Russia are highly sought after by collectors and enthusiasts due to their beauty and rarity. They are often used as decorative pieces or incorporated into jewelry designs, and can also be used for educational purposes or scientific research.
