[9/3 10:00 PM Sale] Synthetic Rutile 3.8mm/0.278ct Loose Gemstone
This is synthetic rutile, which appeared on the market in the late 1940s as an alternative to diamonds. Due to its relatively low hardness of 6 and higher dispersion than diamond (giving it more fire), it was only used as a substitute for a short period.
