Are black diamonds real diamonds? Yes. Black diamonds are genuine carbon diamonds whose color comes from dense dark inclusions (natural) or from treatment. They measure 10 on the Mohs scale, the same as white diamonds, so they are suitable for daily wear.

Natural or treated black diamond — which does Segal use? Both are available. Natural black diamonds are rarer and cost more; treated black diamonds are natural diamonds darkened by heat or irradiation and look identical to the eye. Black moissanite is offered as a lower-cost alternative on most designs.

How much does a black diamond ring cost? Typically less than a comparable white diamond. Segal's black diamond rings start around $1,000 and rise with carat weight, metal, and setting complexity. Every ring is made to order in 14K or 18K gold or platinum.

What prong setting is best for a black diamond solitaire? Four prongs show the most stone; six prongs are more secure for larger carats. A bezel setting fully protects the edges and gives a modern look. All are available on request.

Which band pairs with a black diamond solitaire? A plain band in the same metal, a white-diamond pavé band for contrast, or a black diamond wedding band to match.
