Natural Larimar Slabs Slices

These Natural Larimar Slabs Slices offer collectors and lapidary artists a magnificent glimpse into one of the rarest copper-bearing minerals on Earth. Scientifically classified as a blue variety of pectolite, this unique sodium calcium silicate gets its iconic oceanic coloration from trace amounts of copper replacing calcium within its crystal structure. Because this material is found exclusively within a single mountainous region of the Dominican Republic, authentic raw cuts are highly sought after. These thin sections are sliced to expose the distinct needle-like, acicular crystal growth habits and signature "white wave" pattern formations that mimic the play of sunlight on shallow Caribbean waters.

The semi-polished surface of these Natural Larimar Slabs Slices highlights a dramatic color gradient ranging from soft icy white and pastel turquoise to deep, saturated cerulean blue. The raw material frequently features a contrasting, rugged boundary composed of dark reddish-brown basalt matrix or metallic hematite inclusions, which frames the vibrant blue pectolite beautifully. Because pectolite has a hardness of 4.5 to 5 on the Mohs scale, these slices are cut with precision to ensure structural integrity while highlighting the mineral's natural translucent areas when backlit.

Each of our Natural Larimar Slabs Slices is hand-selected for cabinet display or high-grade cabochon cutting. As a completely natural product, no two slices are alike; one piece may display broad patches of sky blue accented by bold white lines, while another features tightly compressed, dark blue orbicular zones. They are excellent educational pieces for demonstrating how hydrothermal activity alters volcanic rock chemistry, making them a premium addition to any specialized mineral gallery or geology collection.
