Our Materials

Diamond Clarity VVS

Diamond clarity is the assessment of small imperfections on the surface and within the stone. Surface flaws are called blemishes, while internal defects are known as inclusions.

  • VVS diamonds have minuscule inclusions that are difficult even for trained eyes to see under 10x magnification

  • VVS clarity is rare and results in an eye clean appearance

  • Characteristics are minuscule and difficult to see under 10x magnification, even to a trained eye

Certified Diamonds

Our diamonds are certified diamonds that have been graded by a gem laboratory based on their "4 C" attributes of Cut, Color, Clarity and Carat Weight.


When shopping for a diamond, it is highly recommended to purchase a certified diamond to ensure the quality of the stone.

18K Gold

18K gold’s biggest advantage is its purity. As the purest form of gold that’s practical to use in an engagement ring, an 18K gold ring offers the gorgeous appearance of near-pure gold with most of the practical benefits of an alloy.

This extra purity can be especially obvious with 18K yellow or rose gold, which tends to show a  warmer, more vibrant tone.

The higher purity level of 18K gold also makes it less likely to trigger skin allergies than 14K or 10K gold.


We believe sustainability goes hand-in-hand with transparency. From base metals to earring posts or gemstones, we want to make it easy for you to know where your jewelry was made.
