Carat

A carat is the unit used to measure a diamond's weight. One carat equals 200 milligrams or 0.2 grams. Although carat weight and the size of a diamond are related, carat does not directly measure diamond size.

Colourless. High quality diamonds with miniscule traces of colour that can only be detected by a gemologist.
Completely colourless or icy white. Highest possible colour grade and also the most expensive.

Diamonds are graded on their lack of colour. The more colourless a diamond is the higher the quality.

Price

All of our prices are in US Dollars.

Lab

Certified diamonds are graded by expert gemologists who asses quality characteristics including but not limited to carat, colour, clarity and cut. Diamonds above 0.40 carat on our website are certified by one of the top laboratories: GIA, HRD or IGI.

Cut

Offers very little brilliance and fire, and only reflects a small amount of light.
Lowest recommended cut grade. Showcases less brilliance and fire than higher cut diamonds.
High quality cut grade with only slightly less brilliance and fire than an excellent cut diamond, yet at a lower price.
The highest cut grade. Exhibits optimal brilliance and fire, and reflects the most possible light.

The cut of a diamond refers to how well-proportioned its dimensions are. Higher cut diamonds offer the best light performance.

Clarity

Slightly included 1. Inclusions can be seen under 10x magnification but may not be very visible to the unaided eye.

Very, very slightly included 1. Inclusions are very difficult to see even under 10x magnification.
Internally flawless. Rare and beautiful diamonds with no internal flaws.

The clarity of a diamond refers to the absence of inclusions which are impurities on and within the stone.

Advanced

Polish

The finishing and smoothness of a diamond’s facets. Grades of very good or higher are recommended for maximum brilliance.

Symmetry

The alignment of a diamond’s facets and angles. Although not as important as cut, low symmetry grades can still affect a diamond’s brilliance.

Depth

The height of a diamond, from the culet to the table. Depth % is the ratio of the height in relation to the girdle diameter.

Table

The flat facet of a diamond when it is face up. Table % is the ratio of the table width in relation to the girdle diameter.

Fluorescence

The glow that a diamond emits when it is exposed to ultraviolet (UV) light. Strong fluorescence can sometimes make a diamond look milky.
