A 24.36-carat, fancy-intense-yellow diamond set in a ring will lead the upcoming Rago/Wright Fall Jewels sale.

The cushion modified brilliant-cut gem flanked by pear-shaped yellow diamonds is expected to realize $400,000 to $500,000 on October 25 in New Jersey, the auction house said Tuesday. Online bidding is open.

The sale of more than 300 lots features diamonds, colored gems and signed jewels from prestigious jewelry houses, creations from contemporary jewelry artists; and a historically important intaglio collection.

Other pieces included:

A yellow gold ring centered with a 12.58-carat Colombian emerald with “minor traditional clarity enhancement,” according to the auction house. The emerald-shaped gem, flanked by triangular-shaped diamonds, carries an estimate of $90,000 to $140,000.

A Jean Schlumberger for Tiffany & Co. 18-karat yellow gold and platinum ring that features a rectangular-cut emerald framed by pavé-set round brilliant-cut diamond petals. It is predicted to realize $15,000 to $20,000.

There are several jewelry designs from the Native American team of Gail Bird (Pueblo) and Yazzie Johnson (Navajo). These are led by a gem-set, silver and leather belt dated 1989. The materials to create this piece include 10 conchos set with coral, Owyhee jasper, Montana agate, and polka dot jasper, joined by a belt buckle set with jasper. Its estimate is $15,000 to $20,000.

There are at least nine jewelry creations by Philadelphia-based contemporary jewelry artist Michael Manthey. The top lot in this group is the Totem silver and yellow gold pendant, circa 1998, set with titanium quartz, cabochon labradorite, watermelon tourmaline and slate. It is expected to bring in $2,500 to $3,500.
