Product Insights

What does D/VS1 mean for a diamond?

D is the highest colour grade (colourless), and VS1 clarity indicates very slight inclusions — both combine to create an exceptional quality diamond.

Can I gift this as an engagement necklace?

Absolutely — the 1-carat lab diamond and symbolic infinity design make this a meaningful and ethical choice for special occasions or proposals.
