Diamond Search FAQ

Natural diamonds stand out for their rarity, formed over billions of years with unique qualities that lab-grown alternatives can't match. While often considered a long-term investment, they also carry the appeal of owning something naturally rare and distinct.


Conflict-free diamonds are diamonds that have been mined and transported with no connection to any rebel or terror groups and do not support or fund civil wars in any way. We guarantee that we only sell diamonds that have been mined and processed in an environmentally and socially conscious manner. We also exceed regulations set by initiatives such as the Kimberley Process, the Patriot Act, and other governmental and non-governmental measures against the illicit acquirement and distribution of diamonds.

The main benefits of choosing a natural diamond over a lab-grown diamond are its rarity and the unique history behind each stone. Natural diamonds are formed over billions of years, making them more exclusive and often seen as a long-term investment. Additionally, some people appreciate the traditional value and symbolism associated with natural diamonds, which are considered more prestigious due to their natural origin.

Yes, if quality is important to you and you want to buy with confidence. Independent certification labs like GIA or IGI are well-respected and can reliably assess a diamond's quality and verify its authenticity.

The 4Cs—color, clarity, cut, and carat weight—are the main factors that define a diamond's appearance. They also play a significant role in determining the diamond's value and price.

Natural diamonds can retain or even increase in value over time, which can be a crucial advantage if you upgrade, sell, or pass the diamond down as a family heirloom or investment.

Diamond shapes are largely a matter of personal taste and style. Although round diamonds are the most popular choice, opting for a different shape like pear, marquise, or oval can create a more unique look. A princess-cut diamond with its sharp, symmetrical edges is an excellent option for a modern vibe. Ultimately, the shape should match the wearer's personality and style preferences.
