$Very well made 4 ct total weight stud earrings with posts. Mounting is solid 14 kt yellow gold. The delicate gold work exposes the full beauty of these stones. We use a combination of a silicon and gold backs for more stability. Better than today's CZ’s, better than Moissanite. Our Secret Jewelers stones were made over 25 years ago with much higher standards than today's diamond imitations. Each stone is equivalent to an E color diamond and are internally flawless. Their brilliance and fire is a testimony to their craftsmanship and longevity. They will last hundreds of years without discoloration. These stones are better than Moissanite. Mossintinte is a generic material. Their refractive index is much higher than a diamond, cast a yellow tone, looks fake and can be very expensive.
