NEW YORK, NY -- Prices soared at Doyle's March 25, 2021 auction of Important Jewelry as the trend of successful jewelry sales shows no sign of slowing. Featured was exquisite jewelry by the world's most prestigious makers from several distinguished collections -- the Estate of Betty Isreal, the Estate of Mildred Cunningham Brinn, the Estate of Catherine Ann Moore Cavanaugh, and the Estate of a Notable Washington, DC Family.

With competitive international bidding, the sale totaled an exceptionally strong $3,148,740, far surpassing the pre-sale estimate of $1,350,900-1,894,100 with a successful 92% sold by lot and 100% by value.

Highlighting the sale was a dazzling diamond ring that achieved a stunning $529,200, doubling its estimate of $175,000-225,000. Property from the Estate of Betty Isreal, the ring was set with a glittering diamond of approx. 11.57 carats, F color, VS2 clarity.

From the Estate of a Notable Washington, DC Family was a graceful diamond necklace by Cartier that realized $201,600, tripling its estimate of $60,000-80,000. Jewelry set with colored stones featured a Ceylon sapphire and diamond ring from the Estate of Catherine Ann Moore Cavanaugh that sailed past its estimate of $50,000-70,000 to fetch $189,000. A pair of diamond pendant earrings from the Estate of Mildred C. Brinn sold for $176,400, more than doubling their $40,000-60,000 estimate.

The Estate of Betty Isreal
Betty Isreal had a keen eye for design, both in the way she dressed and the way she decorated her home. Chanel, Prada, Donna Karen and Brunello Cucinelli filled the racks in her closet along with J Crew, Gap and Old Navy. She knew what she liked and made it her own. Betty had similarly individual taste in decorating her home. She created a space that truly represented all that she found interesting and beautiful over the years, cultivating a home that was uniquely eclectic and full of life and wonder. Betty was married to her best friend, Seymour Isreal, for 23 years. They were a wonderful couple who clearly respected and loved each other. Seymour was smitten with Betty, and Betty adored Seymour, and they cherished their time together. View Lots
