Frequently Asked Questions
What are kite-shaped side diamonds and why are they paired with an emerald cut?
Kite-shaped diamonds are 4-sided geometric step/brilliant cut accent stones that taper outward from the ring shank toward the center gem. When paired with an emerald cut diamond, their sharp angles and tapered lines create an architectural Art Deco frame that accentuates the clean linear step facets of the center stone while maximizing finger spread.
What is a petal prong basket setting?
A petal prong basket is an artisanal jewelry setting where the metal under-gallery and prongs are hand-sculpted in the shape of delicate flower petals. This design provides structural security for large 4-carat stones while allowing maximum ambient light to enter the pavilion from the sides.
Why is VVS2 clarity critical for a 4 carat emerald cut diamond?
Unlike brilliant-cut shapes (such as rounds or cushions) that have hundreds of small facets to mask tiny inclusions, emerald cuts feature open, rectangular step facets that create a "hall-of-mirrors" window into the stone. In large 4-carat stones, a high clarity grade like VVS2 guarantees the diamond is 100% eye-clean with flawless optical transparency.
What is the total carat weight of the Sardinia ring?
The Sardinia ring has a total carat weight (CTW) of 4.30 carats. This includes the 4.00-carat emerald cut center diamond plus a matched 0.30 ctw pair of kite-shaped side accent diamonds.
What certification and warranty are included?
Every Sardinia ring includes an official IGI (International Gemological Institute) diamond grading certificate verifying its 4.00 carat weight, E color (colorless), VVS2 clarity, and Ideal cut grade. All purchases are backed by GEMNOMADS' Lifetime Manufacturer Warranty and ship via complimentary insured UPS 2nd Day Air with signature confirmation.
