- Documentation of authenticity
-
Step 1
Pick the size of diamond birthstone that suits your purpose. You can select a single large diamond for a simple setting or several smaller diamonds surrounding a larger stone for a display that is more eye-catching.
-
Step 2
Pick the size of diamond that suits your budget.
-
Step 3
While much of the value of a diamond results from its cut, carat weight can give you a broad idea of price.
-
Step 1
Inspect a diamond birthstone for color. Pick a stone that has even, clear white color. Pass on those that have dark streaks or spots that will impair reflective qualities.
-
Step 2
Select a diamond that "speaks," not one that is "silent." A diamond's reflection and refraction of light should make it appear lively rather than dull and static.
-
Step 3
View diamonds under varied light conditions for brilliance. A well-cut diamond should sparkle even under low light.
-
Step 4
Assess the cut of a diamond by its brilliance. One that is cut too thin or too deep will be transparent and will not sparkle with reflected light.
