10k white gold trillion cut pink topaz diamond pendant retail

Product Name: 10k white gold trillion cut pink topaz diamond pendant retail
Solid 10k white gold signed LGL pink topaz trillion cut pendant with small diamond chip accent above the pink topaz. Pendant weighs 0.64 grams. I cannot find the 10k mark, I think the chain it probably once retail came with was signed 10k, sometimes pendants that come with chains aren't marked. It is guaranteed solid 10k gold, I acid tested it to confirm. Pendant shows no sign of wear, no loose or missing stones in excellent condition. Last pic is size reference next to an inch side of ruler. Í.
