Displaying deep black sparkles, this set of Thai black spinel stud earrings and 3-stone ring will become your style statement in no time. Dark and opaque, Thai black spinel is an excellent choice for anyone wishing to own a black gemstone. Accented with milgrain metal artwork, these jewelry pieces feature oval-cut spinel gemstones. Set in a designer frame of sterling silver, these beauties will take your fashion quotient to new heights. In addition, spinel ranks eight on the Mohs scale of hardness, meaning it is suitably scratch-resistant and durable. Natural properties of mined gemstones offer a slight difference in color saturation, hue, and tone. Gemstone images may not always capture these slight differences.
