Gold & Platinum Round 3-Prong Cocktail Earring Mountings with Positive Locking Post & Backs

Secure a round faceted stone in a three-prong cocktail stud that will not walk off the ear, using a positive locking post with its matching locking nut. Each mounting is cast and made in the USA, and every stone seat is listed by millimeter size with an approximate diamond carat weight alongside it, so stone selection stays straightforward.

The series is offered in 14K yellow gold, 14K white gold, 18K yellow gold, 18K white gold and platinum, across stone sizes from 2.0mm (.03ct) to 8.0mm (2.0ct). Mountings are sold individually by the piece, so order two for a matched pair.

Notes

The carat weight listed for each size is the approximate equivalent diamond carat weight and serves as a general sizing reference. Actual fit varies with gemstone cut and proportions, so use the millimeter size when you choose. 14K white gold covers the full 2.0mm to 8.0mm range, and 14K yellow gold runs 2.0mm to 7.5mm, while 18K yellow gold, 18K white gold and platinum begin at 4.0mm.
