An unmounted 133.03-carat yellow diamond is the highlight of an upcoming jewelry auction at Sotheby’s in New York, where it is estimated to fetch up to $5 million.

The cushion modified brilliant-cut, fancy-vivid-yellow, VS2-clarity stone will feature in the December 5 Magnificent Jewels sale, Sotheby’s said Monday. It is among a top 10 made up almost entirely of diamond jewels.

The auction house will also offer 21 items from the collection of iconic American actress Mary Tyler Moore. Proceeds from that sale will benefit The Mary Tyler Moore Initiative, a nonprofit that seeks to preserve and restore vision in people with diabetes. Meanwhile, two gifts from Frank Sinatra to his wife Barbara will go under the hammer, including a Bulgari emerald, diamond and cultured pearl choker and a 16.19-carat diamond ring, each with a presale estimate of up to $350,000.

Here are the rest of the top 10 items:

A necklace featuring two pear-shaped, D-color, internally flawless diamonds weighing 28.45 and 28.21 carats, suspended from two rows of 93 diamonds with a combined weight of 120.20 carats, carries an estimate of approximately $4 million.
This necklace, set with 30 variously cut, D- to G-color diamonds, created by Leviev, has a presale price range of $2 million to $3 million.
Sotheby’s expects this cut-cornered rectangular step-cut, 7.37-carat, fancy-intense-orangey-pink, VS1-clarity diamond to fetch up to $2 million at the auction.
A cushion-modified brilliant-cut, 35.26-carat, F-color, SI1-clarity diamond ring is set to go for up to $1.2 million.
Another ring, by Harry Winston, containing a pear-shaped, 23.65-carat, D-color, VVS2-clarity diamond, has a presale high price of $1.2 million.
This pear-shaped, 21.41-carat, E-color, VVS1-clarity, type IIa diamond ring has an upper price tag of $1 million.
A wreath necklace by Harry Winston, featuring round, pear and marquise-shaped diamonds, has a high estimate of $1 million.
The auction house will offer this Harry Winston wreath bracelet, comprising three pear-shaped diamonds weighing 6.19, 5.01 and 4.98 carats, clustered with smaller diamonds, for up to $850,000.
This Bulgari ring features a cushion-cut, 6.04-carat, Burmese ruby center stone, flanked by trapezoid-shaped diamonds. It carries an upper price tag of $800,000.
