5 Carat Engagement Rings: Showpiece Size Without the Natural Price

All E color, VS1 clarity in our records. Weights are totals; the center is shown where we have it.

House pieces are one of a kind and sell one at a time. Call 954-504-5640 to confirm what is in the case.

At this size, total weight and center weight split apart. R-0067 weighs 5.38 ct in total but carries a 1.82 ct center: most of its weight is in the halo and band. R-0001 puts 4.01 ct in the center. Both are "5 carat rings," and they look nothing alike. If you want a 5 ct center stone, say so, and compare center weights first.

A US size 6 finger is about 16.5 mm across, so a 5 ct round covers about two thirds of it. A 5 ct pear runs from the knuckle line toward the next joint. See carat size on the hand to picture it.

Large natural rough is rare, and natural prices rise steeply with size, so a natural 5 ct center at E VS1 costs many times what a lab stone of the same size and grade costs. Lab-grown prices have fallen sharply since 2020, which pulled 5 ct stones into ordinary engagement budgets. Lab stones are real diamond and must be labeled lab-grown under FTC rules. Natural still wins on rarity and resale; lab wins on size per dollar.

Every house ring is graded E color, VS1 clarity. In plain words: E is the second-whitest grade on GIA's D-to-Z color scale, so the diamond looks icy white even next to white paper. VS1 means the diamond has small inclusions that a trained grader finds with effort under 10x magnification; with the naked eye it looks clean.

At 11 mm, the top of the stone is a wide window. A warm tint or a dark inclusion that hides in a 1 ct stone becomes visible here, so the E VS1 standard earns its keep on big stones.

• Choose six prongs, claw prongs or a bezel. Four thin prongs are not enough for a stone this size.
• Pick 14K gold or platinum for the head; both hold prongs firmly.
• Insure it on a scheduled jewelry rider. Every order we ship is insured on the way to you.
• Clean weekly. Big stones show dirt and lotion more than small ones.
• Take it off for the gym, the beach and heavy work.

A common choice at this budget is a lab-grown stone at 4 to 5 carats or a natural stone at around 2. The lab ring looks bigger; the natural ring is rarer. Neither is the wrong answer, and you can see both side by side in the showroom.

All sales are final and resizing is not part of our published policies, so measure before you buy. Ask about the grading paperwork for the exact ring.
