A Private Jeweler in Alam Sutera: Natural Diamonds and 18K Gold
Choosing jewelry often begins with a photograph. For an engagement ring, wedding ring, or meaningful gift, seeing and trying a piece in person helps you understand its proportions, comfort, and individual details.
As a private jeweler in Alam Sutera, Kimfook offers personal consultations focused on natural diamonds and 18K gold jewelry. Our showroom is at Ruko Spectra, serving customers from West Jakarta, South Jakarta, Pantai Indah Kapuk (PIK), and beyond.

What Is a Private Jeweler?
A private jeweler takes a personal approach to selecting jewelry. The conversation begins with your occasion, preferred design, everyday style, and budget, so that the options you consider are relevant to you.
At Kimfook, you can start a consultation through WhatsApp and continue at the showroom. Discuss an existing collection or a custom design, then arrange a visit to try and compare suitable pieces.
Visiting a Showroom Outside a Mall
Our Ruko Spectra showroom is a dedicated setting for viewing jewelry and discussing details with our team. You can explore a favorite design, try a size, and consider the choice of stone and gold.
Before visiting, note our address: Jalan Jalur Sutera Utama, Ruko Spectra Blok 23B No. 12, Alam Sutera. Send a photograph or catalog link through WhatsApp so our team can check availability in advance.
Natural Diamonds and 18K Gold
Kimfook uses only natural diamonds in its diamond jewelry collections. Each stone should be considered individually. Carat weight, cut, color, and clarity describe its characteristics, while viewing the jewelry helps you assess its appearance and proportions.
18K gold contains 75% gold and is also identified by the 750 mark. Discuss gold colors and settings according to the available collection or your custom design, and confirm the final material specifications in your purchase documents.
Kimfook’s 18K gold jewelry follows SNI 8880:2025, Indonesia’s national standard for gold articles. This standard reference is also listed on Kimfook’s official Instagram profile.
Understanding Gold and Diamond Checks at Kimfook
Clear information about materials is part of the consultation. Kimfook has an XRF Tester and an OGI Diamond Screener for internal checks. These instruments serve different purposes.
XRF Testing for Metal Composition
XRF helps analyze the metal composition of the area being examined. Results should be interpreted according to the testing method and the instrument’s scope, and can support a discussion about the jewelry’s materials.

Diamond Screening and Gemological Reports
The OGI Diamond Screener is used in the diamond screening process. Screening results need to be understood within the instrument’s capabilities; stones requiring further identification can be referred to a gemological laboratory.
For diamonds in the Diamond GIA collection, ask for the GIA report corresponding to the stone you choose. Store documents, internal screening results, and gemological reports serve different purposes. Learn more about the equipment at Kimfook Lab.
