Faceted Glass Rhinestones / Costume Jewelry Studs

The image features two small, faceted transparent items that appear to be loose rhinestones or the decorative heads of stud earrings. The central item is a faceted, round brilliant-style cut stone, likely made of glass or acrylic rather than a precious gemstone, indicated by the quality of light refraction and visible edge wear. To its right, a smaller similar object is visible with a post and a translucent butterfly-style backing attached, confirming its use as costume jewelry. The larger center piece appears to be approximately 6-8mm in diameter. Both pieces are clear/colorless and are resting on a dark, textured gray or black surface that contains reflective glitter fragments, which may be a jewelry display card or craft foam. There are no visible maker's marks or metal stamps in this view. The condition shows some surface scratching and minor chipping on the facet edges of the larger stone, suggesting frequent use or loose storage. The overall craftsmanship suggests mass-produced contemporary fashion jewelry or craft embellishments from the late 20th to early 21st century. The items lack the high-index brilliance of true diamonds or high-grade cubic zirconia, pointing towards standard leaded glass or crystal composition.
