Deals 10k white gold trillion cut pink topaz diamond pendant

Product Name: Deals 10k white gold trillion cut pink topaz diamond pendant
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 came with was signed 10k deals, 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.
