Freeman’s leads Newman estate sale with 19.12-carat diamond ring

A 19.12-carat emerald-cut diamond ring will set the investment benchmark in Freeman’s June 10 Important Jewelry sale in New York, where it carries a $350,000 to $450,000 estimate. Mounted in platinum with bullet-shaped side diamonds totaling about 1.35 carats, the stone is the kind of large natural diamond that turns a catalog lot into a live test of appetite at the top end of the market.

The ring matters even more because of who wore it before it reached the block. Sandra Schultz Newman, Montgomery County’s first female assistant district attorney and the first woman elected to the Pennsylvania Supreme Court, bought the diamond with winnings from her record-setting racehorse, Nihilator. Newman died on February 2 at 87, and Freeman’s has framed the jewelry as part of a collection shaped by a woman with a sharp eye for objects with presence and personality.

On paper, the stone is exactly the sort of diamond serious buyers read closely: F color, SI1 clarity and no fluorescence. That combination places the emphasis on scale and cut, not perfection, and it helps explain why the estimate feels anchored rather than speculative. In today’s market for large natural diamonds, the value is not only in the carat weight but in how cleanly the jewel presents, and this ring has the added advantage of being fully documented, from the platinum mounting to the 19.12-carat emerald cut.

Freeman’s broader Gavel & Grace estate series will begin in New York before a dedicated single-owner sale in Philadelphia on June 23 and an online Essential Jewelry sale on June 24. The Newman grouping also includes a diamond, sapphire and gold horse brooch, a gold equestrian bracelet and an enamel-and-gold stick pin showing a harness race in action, details that keep the estate’s sporting thread visible without distracting from the diamond’s scale.

Nihilator gives the jewelry its most distinctive provenance. Foaled in 1982 and elected to the Harness Racing Museum’s Hall of Fame in 1995, the pacer won 35 of 38 starts, earned $3,225,653 and paced in 1:49.3 on Hambletonian Day in 1985, the fastest mile to that date. If the ring lands near or above estimate, it will signal that high-end diamond liquidity remains healthy for trophy stones with real history behind them, and that narrative ownership still matters most when the jewel itself is already exceptional.
