This Amendment No. 3 amends the Schedule 13D filed with the Securities and Exchange Commission (the “Commission”) on June 11, 2012 (the “Original 13D”) by Yu Zhen Industrial Limited (“Yu Zhen”) with respect to $.01 Par Value Common Stock (the “Common Stock”) of LJ International Inc. (the “Issuer”), as previously amended by Amendment No. 1 to the Original 13D filed on July 16, 2012 (“Amendment No. 1”) and Amendment No. 2 to the Original 13D filed on October 1, 2012 . Unless otherwise stated herein, the Original 13D as previously amended remains in full force and effect.

Item 4.

Purpose of Transaction

Item 4 is hereby amended and restated in its entirety as follows:

Yu Zhen originally acquired the Common Stock that is the subject of this Schedule 13D for investment purposes. With respect to the recently proposed “going private” transaction involving the Issuer as described in the Issuer’s Schedule 13E-3 filed on April 3, 2013 (the “Transaction”), Yu Zhen believes that the terms of the proposed Transaction substantially undervalue the Issuer. In response to what it believes to be an inadequate offer, Yu Zhen may pursue any or all of the following actions: communications with other shareholders of the Issuer regarding the Transaction, communications with the sponsors of the Transaction, disposing of all or a portion of the Common Stock in open market sales or in privately negotiated transactions, exercise of its dissenters’ rights and seeking other legal recourse to protect its interests as a shareholder.

Yu Zhen reserves the right to determine in the future whether to change the purpose or purposes described above or whether to adopt plans or proposals of the type specified in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5.

Interest in Securities of the Issuer

Item 5 is hereby amended and restated in its entirety as follows:

(a) See Items 11 and 13 of the cover page to this Schedule 13D, Amendment No. 2 for the aggregate number and percentage of shares of Common Stock that are beneficially owned by Yu Zhen as of April 9, 2013.

(b) See Items 7 through 10 of the cover page to this Schedule 13D, Amendment No. 2 for the number and percentage of shares of Common Stock beneficially owned by Yu Zhen as of April 9, 2013 as to which there is sole or shared power to vote or direct the vote, and sole or shared power to dispose or direct the disposition.

(d) No other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities covered by this Schedule 13D.

(e) Not applicable.
