Claim 14:
15. A method of forming a plurality of diamonds, the method comprising:
providing a substrate holder with a cavity containing a base, the base comprising a base material composition;
epitaxially forming a first sacrificial layer on the base and within the cavity, the first sacrificial layer having a first material composition;
epitaxially forming a first diamond layer on the first sacrificial layer within the cavity, the first diamond layer being a material that is different from the first material composition;
epitaxially forming a second sacrificial layer on the first diamond layer within the cavity, the second sacrificial layer being the first material composition;
epitaxially forming a second diamond layer on the second sacrificial layer within the cavity,
the first sacrificial layer, the first diamond layer, the second sacrificial layer, and the second diamond layer being part of a heteroepitaxial super-lattice; and
separating the first and second diamond layers from the first and second sacrificial layers to produce free standing, single crystal diamonds.
