What You Get That They Don't Offer

• 3 carat blue center stone — blue diamonds are the most expensive fancy color at competitors, often limited to 1 carat at this price tier
• 4 CTW total — a size and impact that Brilliant Earth prices at $8,000+ and Blue Nile at $6,000+
• Blue diamonds are the rarest fancy color — historically reserved for royalty and collectors. Lab-grown technology delivers the identical deep blue at a fraction of mined prices
• Three metal karat options including 10K — a budget-friendly entry point that competitors don't offer
• Handcrafted specifically for you — your metal, your size, your gold color
• Insurance included at no additional cost
