CUSTOM OPTIONS

With such a wide variety of diamonds on the market, it can be overwhelming for buyers to find the right stone. To ensure your diamond is as high quality, beautiful, and durable as can be, we work together with our trusted vendors to acquire a stunning diamond you’ll love to use in your jewelry creation.

Takayas is a certified gemologist, and he personally inspects every stone that our small network of vendors shows us before choosing the best diamond for your project.

We want you to be 100% satisfied with the diamond we acquire for you, and we will provide you with everything you want to know about your diamond. All of our 0.50 ct. and up diamonds come with an official grading report from GIA (the Gemological Institute of America) or EGL (the European Gemological Laboratory).

Your diamond’s grading report will include details of your diamond’s identifying characteristics, such as color, clarity, carat weight, etc. This report will also contain a unique report number that has been specifically assigned to your individual stone.

Diamonds that are 0.25 ct. and smaller are not typically sold with a physical grading report. We can acquire grading reports for these stones upon request.

We also work with a variety of colored diamonds. Popular diamond color options include pink, yellow, blue, champagne, and black.

DIAMOND EDUCATION: THE 4 C’S

When it comes to selecting a diamond, the 4 C’s – cut, color, carat weight, and clarity – are the universal standard used to assess the characteristics of a stone.

CUT

A diamond is cut to maximize its brilliance, and a cut is graded based on how the diamond’s facets interact with light. A diamond’s cut will range from Excellent to Poor based on its brightness (the amount of light it reflects internally and externally), fire (the rainbow-colored flashes of light that are reflected back when exposed to light), and scintillation (the amount of sparkle), as well as weight ratio, polish, and symmetry.

COLOR

A diamond’s color is graded to determine its relative absence of color. The “whiteness” of diamonds is graded using a color scale which ranges from D (colorless) to Z (light yellow or brown). For “colorless” and some “near colorless” grades of diamonds, these color distinctions are so slight that they are often undiscernable by the untrained eye.

CARAT WEIGHT

A diamond’s carat weight is the standard unit of weight used to measure diamonds and other gemstones. Carat weight is measured with a highly precise electronic scale, rounded to the nearest hundredth of a carat. When choosing a diamond, it is useful to remember that a stone’s carat weight is a separate measurement from its diameter. For example: a 0.49 ct. diamond may appear larger when viewed from a top-down angle in a ring’s setting compared to a 0.50 ct. diamond, if the lighter-weight stone has a larger table diameter measurement. (The chart below shows average table diameter measurements associated with carat weights.)

CLARITY

A diamond’s clarity is based on the number, size, and visibility of the tiny internal imperfections (inclusions) and external imperfections (blemishes) that occur in almost all natural diamonds. Many of these imperfections can only be seen under a microscope, and they do not affect a diamond’s beauty in any visibly discernible way.

A diamond is assigned a clarity grade by a trained grader who will evaluate the stone under 10x magnification; this grade will range from F (flawless) to I (included).
