Frequently Asked Questions

ffulla is a fine jewelry brand creating engagement rings, wedding rings and fine jewelry with an emphasis on meaning, design and lab-grown diamonds. Collections may include classic diamond shapes, colored lab-grown diamonds, Round Modified designs and selected Cut For You projects.

A lab-grown diamond is diamond crystal created in a controlled environment. It has the same fundamental chemical composition, crystal structure and optical characteristics as a mined diamond. It is not cubic zirconia, moissanite or another diamond simulant. The primary difference between a lab-grown and mined diamond is origin.

CVD and HPHT are the two principal methods used to grow diamonds in controlled environments. Chemical Vapor Deposition builds diamond crystal from activated carbon-rich gas, while High Pressure High Temperature growth uses very high pressure and temperature. The growth method alone does not determine a diamond’s final quality.

Yes. Lab-grown diamonds can display color influenced by trace elements, structural features, growth conditions or post-growth treatment. Hue, tone, saturation and cut all affect the appearance of an individual colored diamond.

Depending on the individual diamond or jewelry piece, documentation may be issued by IGI, NGTC or GRC. A Light Performance Report may also be provided for selected diamonds. A Light Performance Report is separate from a diamond grading certificate. Review the individual product page or contact ffulla to confirm the documents provided with a specific item.

Depending on the product, available materials may include 18K yellow gold, 18K white gold, 18K rose gold, Pt950 and plated finishes for selected fine jewelry. Not every product is available in every material. Review the individual product page for the available options and stated specifications.

Review the Product Details section of the individual product page. Depending on the design, the page may include material, stone, setting, dimensions, available options, documentation and order-status information. Contact ffulla if a specification you need is not shown.

For the most accurate result, have the intended finger measured by a professional jeweler using the US ring-size system. Use our Ring Size Guide to compare US, Hong Kong and international sizes. Finger size can vary by hand, temperature and band width. If you are between sizes or choosing a wider band, contact ffulla before ordering.

Resizing depends on the ring’s design, setting, material and required adjustment. Full eternity bands and rings with stones extending around the band may be difficult or impossible to resize. Contact ffulla to confirm whether a specific ring can be resized before arranging any service.

Store jewelry separately in a clean, dry place and avoid impact, harsh chemicals and abrasive cleaning. Remove jewelry before strenuous activity or situations that may expose it to pressure or damage. Care requirements can vary by material, gemstone and setting, so contact ffulla if you need guidance for a specific piece.
