For all gemstones, purity of color is the most important factor and diamonds are no different white is the most sought after and our experts look for variations within those shades of white.

Diamonds that have a faint to light color tone are rejected.

Lighthouse diamonds only provides diamonds that can be classified as near colorless.

Diamond Clarity

Diamond clarity is assessed the same way for natural diamonds and for lab grown diamonds.

Inclusions and internal characteristic are evaluated under 10x magnification. Because inclusions are obstacles to light refracting within the diamond, they affect the sparkle.

The lower the clarity and the less brilliant the diamond will be.

Every diamond from Lighthouse Diamond is evaluated for clarity and falls within a very narrow grading range.

Diamond Carat

Carat is a unit of weight for gemstones. Derived from carob seeds which are all very close in size, this unit of measure dates back to Greek times. There are 5 carats in 1 gram.

A difference between natural diamonds which are priced based on the rarity of larger sizes, our prices for lab grown diamonds are linear. At $800 per carat, that means that whether you purchase a diamond a half carat diamond is exactly one half the price of a full carat diamond.
