Lab-Created Diamonds vs. Moissanite - The James Allen …
This silicon carbide crystal is a completely different material that looks very similar to diamond but is still an imitation of the real thing. Moissanite is often marketed as a cheaper alternative to diamond, but it’s an inferior option given the pricing and availability of ‘real’ lab-created diamonds.
Ceramic Armor - DIAMOND AGE
15/5/2018· Small quantities of silicon carbide (“Class II”) and boron carbide (“Class III”) ceramic vests were subsequently produced and issued to aircrews. The class-threes were originally made of hot-pressed boron carbide tiles, arranged in a mosaic-type array of small plates, and were extremely expensive to produce.
