Our Diamonds

Natural Mined Diamonds

Diamonds possess distinguishing characteristics. The 4Cs—color, clarity, cut and carat weight—are the standards to assess the quality of a diamond. The cut refers to how a diamond’s facets interact with light. With its symmetry, proportion and polish, the cut will  determine the beauty of the diamond. If a diamond is cut well, it will reflect and refract light with pure brightness and sparkle. The color grade directly affects the stone’s appearance. The color ranges from D-Z with D being the whitest. Diamonds on the middle to lower end of color grade can appear slightly warmer, but can also be desirable with their uniquely golden tones. A diamond’s clarity grade determines its natural inclusions, which can affect its brilliance. But not all inclusions are equal! Depending on the size and type of inclusion and its placement, this can give the consumer significant savings on their diamond purchase. Carat weight can give a different visual size across different diamond shapes. A diamond may have a smaller carat weight but can appear larger if one is cut slightly shallower than the other and vice versa. We assist our clients in selecting their dream stone within their varied budgets by fine tuning their priorities within the 4Cs to achieve their overall look and goal. Our diamonds are hand selected and are certified by the world’s leading gemological institutes such as GIA and GCAL.

Antique Diamonds

Our certified antique diamonds were cut and polished by hand and eye in the era before computers and lasers. These old world cutters and craftsmen understood the raw material and could maximize the amount of life and beauty from the diamond rough using stunning cuts that were not restricted by today's commercial standards, but cut to maximize carat weight. For the ethically conscious consumer, they are recycled and are a responsible source of diamonds. Antique diamonds that we feature were cut during the 19th and early 20th centuries. These antique diamonds were often cut before the advent of electricity and were initially designed to sparkle in low levels of lighting and to look as shimmering and magnificent by candlelight as they do in daylight. The shapes and cuts we love and feature are old mine, old European, antique movals (marquise ovals), antique ovals, rose cuts and antique emerald cuts.

Lab Grown Diamonds

Our certified lab grown diamonds, apart from the process in creating them, are identical to earth mined diamonds, but are more ethical and affordable. In comparison to other mined diamond alternatives, such as cubic zirconia and moissanite - lab grown diamonds are 100% pure crystallized carbon. They are meticulously created in a lab using cutting-edge technology that replicates the natural diamond growing process. The result is a man-made diamond that is chemically, physically, and optically the same as those that are naturally mined. They are then cut, polished and graded just like earth mined diamonds. They also possess the same refractive diamond index, dispersion, and hardness, and are graded to the same high standards as mined diamonds by leading gemological institutes including IGI, GIA and GCAL.

Moissanite

Moissanite was first discovered in small quantities from tiny particles carried to Earth by a meteorite thousands of years ago by the Nobel winning French chemist Henri Moissan in Arizona in 1893. Naturally occurring moissanite is so scarce that there isn’t enough to even make a pair of earrings. Therefore, all moissanite used in jewelry today is lab-created. It is now available in a wide array of different shapes, cuts and sizes. Unlike other diamond alternatives that can dull and scratch over time, moissanite is guaranteed to never lose its optical properties. It is not porous like cubic zirconia and registers between 9.25-9.5 on the MOHS hardness scale (a diamond is a 10.) You can enjoy your moissanite with absolutely no maintenance other than the occasional cleaning.
