Johanne Lab Grown Diamond Pendant Necklace vs Gem Stone King Lab Grown Diamond Pendant

Buy the Johanne if you want a small, adjustable everyday pendant in a choice of carat weights and lengths. Buy the Gem Stone King if you want a single larger 1 ct stone with IGI certification on a fixed 18-inch rope chain. Both are solid 14k yellow gold with spring clasps, and reviewers of both brands praise the finish and gift-ready packaging. The Johanne's 110 ratings average 5 out of 5, but that is a small sample; Gem Stone King has a longer track record as a family jeweler since 1903.

• Choose the Johanne if you want a subtle floating diamond you can wear at 16, 17 or 18 inches and pick the carat weight that suits you.
• Choose the Gem Stone King if you want a visibly larger 1 ct lab grown diamond with IGI certification and a fixed 18-inch rope chain.
