**Comment for Reporting Person:** This Amendment No. 1 (this "Amendment") amends and supplements the Schedule 13D filed by Duc Pham (the "Reporting Person") with the U.S. Securities and Exchange Commission on August 22, 2025 (the "Original Schedule 13D," SEC Accession No. 0001376474-25-000764) with respect to the common stock, par value $0.001 per share (the "Common Stock"), of Charles & Colvard, Ltd. (the "Issuer"). Capitalized terms used and not defined herein have the meanings set forth in the Original Schedule 13D. Except as specifically amended hereby, the Original Schedule 13D remains in full force and effect.

**Item 1. Security and Issuer**

**(a) Title of Class of Securities:**
Common Stock

**(b) Name of Issuer:**
CHARLES & COLVARD LTD

**(c) Address of Issuer's Principal Executive Offices:**
170 SOUTHPORT DRIVE, MORRISVILLE, NC, 27560

**Item 4. Purpose of Transaction**

On August 25, 2025 the Reporting Person delivered a written advance notice nomination to the issuer corporate secretary by FedEx and UPS pursuant to the issuer bylaws and Rule 14a-19 under the Securities Exchange Act of 1934. The nomination is for election of the Reporting Person to the board of directors at the 2025 annual meeting scheduled for October 13, 2025. The Reporting Person intends to solicit proxies from holders representing at least 67 percent of the voting power entitled to vote in the election of directors and to furnish a universal proxy card in accordance with Rule 14a-19. The Reporting Person intends to comply with Rule 14a-19 including any required notices of changes and the certification in Rule 14a-19(f).
The Reporting Person may file preliminary or definitive proxy statements and additional soliciting materials and may communicate with shareholders and other market participants regarding the issuer, board composition, governance, strategy, and performance. The Reporting Person may evaluate additional plans or proposals with respect to the matters listed in Items 4(a) through 4(j) of Schedule 13D and reserves the right to take actions described in those items subject to applicable law.
Except as described above, the information regarding plans or proposals in the Original Schedule 13D is unchanged.

**Item 5. Interest in Securities of the Issuer**

**(a)**
As previously reported in the Original Schedule 13D, the Reporting Person beneficially owns approximately 4.99 percent of the outstanding Common Stock. There is no change to the amount or percentage beneficially owned.

**(b)**
No change to the Reporting Person voting or dispositive power from the Original Schedule 13D. As described in Item 6, the Reporting Person has meeting limited voting power with respect to 144,000 shares held by Don Pham under a proxy that applies only to the 2025 annual meeting, and has no dispositive power or economic power over those shares.

**(c)**
Since the filing of the Original Schedule 13D on August 22, 2025, the Reporting Person has not effected any transactions in the Common Stock. During the 60 days prior to this filing, there were no transactions by the Reporting Person.

**Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.**

On August 20, 2025, Don Pham and the Reporting Person entered into an irrevocable proxy voting agreement. Under this agreement, Don Pham granted the Reporting Person voting power only with respect to 144,000 shares of Common Stock for the 2025 annual meeting of shareholders. The proxy is meeting limited and does not grant the Reporting Person dispositive power or any economic rights in those shares. Don Pham retains full beneficial and dispositive ownership of the shares. The Reporting Person paid consideration of 10,000 dollars for the proxy.

Other than the proxy described above, the Reporting Person has no contracts, arrangements, understandings, or relationships with any person with respect to any of the issuer securities, including but not limited to options, swaps, short positions, borrowed or loaned shares, pledges, or performance based fees.

The proxy agreement is Exhibit 99.1 to the Original Schedule 13D filed on August 22, 2025, and is incorporated by reference into this Amendment.
