Natural Diamonds

Our natural diamond inventory includes round brilliant diamonds, fancy shapes and specialty cuts for fine jewelry, engagement rings, bridal collections and other jewelry applications.

Available stones vary by carat weight, color, clarity, shape, proportions and other specifications. Certification information is provided where applicable on individual diamond listings.

Lab-Grown Diamonds

Our lab-grown diamond collection includes a range of shapes, sizes and specifications for jewelry businesses seeking laboratory-grown diamond options.

Lab-grown diamonds have essentially the same chemical composition and crystal structure as natural diamonds. Individual stones can be evaluated according to characteristics such as carat weight, color, clarity, shape, dimensions, and certification.

Fancy Shape Diamonds

Fancy shape diamonds offer designers alternatives to traditional round diamonds and can create distinctive silhouettes for modern and classic jewelry.

Our specialty inventory includes shapes such as:

Hexagonal · Kite · Marquise · Pear · Oval · Lozenge · Trapezoid · Ashoka-style · Baguette · Shield · Triangle

Availability varies, so contact our team if you are searching for a specific shape, size or proportion.

Diamond Matching Pairs

Matched diamond pairs are important for earrings, side stones and symmetrical jewelry designs.

Our matching-pair inventory can include stones selected according to characteristics such as shape, size, color, clarity and overall appearance.

If you require a particular pair, provide your specifications and our team can review available options.

Diamond Layouts & Calibrated Sets

Diamond layouts are useful for jewelry manufacturers and designers working with multi-stone designs.

Depending on the inventory, layouts may include coordinated stones in shapes such as pear, marquise, baguette, oval, half moon, heart, trilliant, and other specialty cuts.

Each product listing should be reviewed for its exact stone count, dimensions, total carat weight and other specifications.
