Field notes
The sample sale page separates hammer totals from buyer’s premium, with the premium amount explicitly labeled as an estimate. Its lot entries pair estimate ranges and multiples of the high estimate with details such as stone origin and treatment; the sale summary also reports that 86 of 87 lots sold. The site names gemmologist Chaïma Teisseire as its author.
