Note on Carat Weight: 3-Stone Masterpiece

Important Notice: The selected carat weight represents the Total Carat Weight (TCW) of all three diamonds. To ensure the most breathtaking aesthetic, Bowtie carefully selects two side stones that perfectly complement your chosen center stone's dimensions.

Our Golden Ratio Breakdown: Here is how your total carat weight is distributed between the center stone and the two side stones to achieve the iconic look shown in our photos:

  • 1.00 ct total = 0.50 ct Main Stone + 0.50 ct Side Stones (0.25 ct each)
  • 1.50 ct total = 0.80 ct Main Stone + 0.70 ct Side Stones (0.35 ct each)
  • 2.00 ct total = 1.00 ct Main Stone + 1.00 ct Side Stones (0.50 ct each)
  • 2.50 ct total = 1.50 ct Main Stone + 1.00 ct Side Stones (0.50 ct each)
  • 3.00 ct total = 2.00 ct Main Stone + 1.00 ct Side Stones (0.50 ct each)
  • 3.50 ct total = 2.00 ct Main Stone + 1.50 ct Side Stones (0.75 ct each)
  • 4.00 ct total = 2.50 ct Main Stone + 1.50 ct Side Stones (0.75 ct each)
  • 4.50 ct total = 3.00 ct Main Stone + 1.50 ct Side Stones (0.75 ct each)
  • 5.00 ct total = 3.00 ct Main Stone + 2.00 ct Side Stones (1.00 ct each)

For High-End Collector Sizes (6.0ct – 10.0ct): For these monumental sizes, we utilize a specialized Masterpiece Ratio to maintain structural integrity and visual grandeur:

  • 6.00 ct total = 4.00 ct Main Stone + 2.00 ct Side Stones (1.00 ct each)
  • 8.00 ct total = 5.00 ct Main Stone + 3.00 ct Side Stones (1.50 ct each)
  • 10.00 ct total = 6.00 ct Main Stone + 4.00 ct Side Stones (2.00 ct each)

The Bowtie Difference: We don't just "fill" the weight. Each side stone is hand-picked to match the Color and Clarity of your center stone, creating a seamless river of light across your finger.
