Only in yellow gold. At 4 carats, J's warmth through the oval's elongated shape is very prominent with visible tip concentration. Yellow gold absorbs the warmth. Maximum savings with clear trade-offs.

At 4 carats, a J color oval is near-colorless, meaning it is a warm tone that becomes part of the diamond's character. Warmth may be visible in white metal settings but disappears in yellow or rose gold. In white gold or platinum, J color faces up clean and bright. In yellow or rose gold, any faint body color becomes completely imperceptible against the warm metal. The oval cut's brilliant-cut faceting creates lively sparkle that complements any metal.
