Frequently Asked Questions
What is the difference between an Old Mine Cushion Cut and a Modern Cushion Cut?
Old Mine Cushion Cut (OMC): An authentic vintage cutting style originating in the 18th and 19th centuries. It features a smaller table, higher crown, steeper pavilion, and larger, chunkier facet patterns that produce broad, bold flashes of colored light (fire) rather than modern crushed-ice sparkle.
Modern Cushion Cut: Cut with a larger table and lower crown, optimized for smaller pinpoint reflections and modern brilliance.
What are Cadillac cut side stones?
Cadillac stones (also called epaulettes) are 5-sided geometric step-and-brilliant cut diamonds that taper from the wide girdle of the cushion center stone down to the shank, creating a seamless visual flow and broad finger coverage.
Can I stack a straight wedding band flush with the Teresa ring?
Yes! The Teresa is crafted with an elevated high-profile setting. The base of the diamond baskets sits above the shank, allowing standard straight or eternity wedding bands to slide completely flush without leaving a gap.
What certification is included with the center diamond?
Your center diamond includes an official IGI (International Gemological Institute) certificate verifying its 3.00 carat weight, E color, VVS2 clarity, and Ideal cut proportions.
What is the crafting timeframe and warranty?
Each piece is made to order in our Austin, Texas design studio in 3 to 4 weeks (with rush orders available upon request). All orders include our Lifetime Manufacturer Warranty and are shipped via complimentary insured express delivery with signature required.
