Highlights

269-5337 Ring: extremely high-quality, modern diamond ring, yellow cushion-cut centre stone, 5.03ct Ca. Ø 17.5 mm, ring size 55, ca. 5.5 g, 18K white gold/yellow gold, in the center an extremely valuable yellow diamond in the upper clarity range, very light yellow to light yellow, at least VS, fantastic cut resulting in high brilliance, accompanied by 2 bright, white trapezoid diamonds and small brilliant-cut diamonds on the shoulders, as good as new and unworn. The starting/offer price already includes 19% German VAT. Buyers with a delivery address outside the EU will not have to pay this tax, and the price will be reduced by 19% for such buyers. 24.000 € - 50.000 €

269-5317 Wristwatch: Rolex Day Date Borke Ref. 18078 from 1986, new old stock, box and papers Approx. Ø36mm, ca. 147g, 18K gold, Ref. 18078, serial number 9364924, bezel set with diamonds, automatic chronometer, dial with window for date and day of the week, centre seconds, dial set with diamonds and rubies, original "Borke" bracelet with deployant clasp, intact, cleaning/revision recommended. The watch is in its original box with original papers from 1986 and is probably unworn. In our opinion, the stone setting is not by Rolex, but subsequently commissioned by a customer, although it is of the highest quality! The watch has been in the safe since 1986, is an inheritance and is in incredibly good condition. 19.000 € - 35.000 €
