Transparent Lab Cabochons

Transparent Lab Cabochons


These synthetic cabochons bring a transparent gemstone feel to your jewelry along with the ease of bezel setting. Cabochons were among the first ways that gems were set in the crowns, sceptres, and jewelry of ancient royalty, so using gem cabochons makes you part of a great tradition. These cabs are wonderfully affordable because they have been created in a lab. Chemically, they are real corundum, spinel, or manufactured cubic zirconia, but they are much clearer and tougher than many of their mined namesakes, and they have the added advantage of being heat-resistant. NOTE: The price will depend on the size that you select. Next to each size is shown the number of stones (pcs) in stock, but we can easily backorder more if you need them.
